|
release branch.
|
|
|
|
Changes between 1.1.1r and 1.1.1s [1 Nov 2022]
|
|
|
|
*) Fixed a regression introduced in 1.1.1r version not refreshing the
|
|
certificate data to be signed before signing the certificate.
|
|
|
|
[Gibeom Gwon]
|
|
|
|
Changes between 1.1.1q and 1.1.1r [11 Oct 2022]
|
|
|
|
*) Fixed the linux-mips64 Configure target which was missing the
|
|
SIXTY_FOUR_BIT bn_ops flag. This was causing heap corruption on that
|
|
platform.
|
|
[Adam Joseph]
|
|
|
|
*) Fixed a strict aliasing problem in bn_nist. Clang-14 optimisation was
|
|
causing incorrect results in some cases as a result.
|
|
[Paul Dale]
|
|
|
|
*) Fixed SSL_pending() and SSL_has_pending() with DTLS which were failing to
|
|
report correct results in some cases
|
|
[Matt Caswell]
|
|
|
|
*) Fixed a regression introduced in 1.1.1o for re-signing certificates with
|
|
different key sizes
|
|
[Todd Short]
|
|
|
|
*) Added the loongarch64 target
|
|
[Shi Pujin]
|
|
|
|
*) Fixed a DRBG seed propagation thread safety issue
|
|
[Bernd Edlinger]
|
|
|
|
*) Fixed a memory leak in tls13_generate_secret
|
|
[Bernd Edlinger]
|
|
|
|
*) Fixed reported performance degradation on aarch64. Restored the
|
|
implementation prior to commit 2621751 ("aes/asm/aesv8-armx.pl: avoid
|
|
32-bit lane assignment in CTR mode") for 64bit targets only, since it is
|
|
reportedly 2-17% slower and the silicon errata only affects 32bit targets.
|
|
The new algorithm is still used for 32 bit targets.
|
|
[Bernd Edlinger]
|
|
|
|
*) Added a missing header for memcmp that caused compilation failure on some
|
|
platforms
|
|
[Gregor Jasny]
|
|
|
|
Changes between 1.1.1p and 1.1.1q [5 Jul 2022]
|
|
|
|
*) AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised
|
|
implementation would not encrypt the entirety of the data under some
|
|
circumstances. This could reveal sixteen bytes of data that was
|
|
preexisting in the memory that wasn't written. In the special case of
|
|
"in place" encryption, sixteen bytes of the plaintext would be revealed.
|
|
|
|
Since OpenSSL does not support OCB based cipher suites for TLS and DTLS,
|
|
they are both unaffected.
|
|
(CVE-2022-2097)
|
|
[Alex Chernyakhovsky, David Benjamin, Alejandro Sedeño]
|
|
|
|
Changes between 1.1.1o and 1.1.1p [21 Jun 2022]
|
|
|
|
*) In addition to the c_rehash shell command injection identified in
|
|
CVE-2022-1292, further bugs where the c_rehash script does not
|
|
properly sanitise shell metacharacters to prevent command injection have been
|
|
fixed.
|
|
|
|
When the CVE-2022-1292 was fixed it was not discovered that there
|
|
are other places in the script where the file names of certificates
|
|
being hashed were possibly passed to a command executed through the shell.
|
|
|
|
This script is distributed by some operating systems in a manner where
|
|
it is automatically executed. On such operating systems, an attacker
|
|
could execute arbitrary commands with the privileges of the script.
|
|
|
|
Use of the c_rehash script is considered obsolete and should be replaced
|
|
by the OpenSSL rehash command line tool.
|
|
(CVE-2022-2068)
|
|
[Daniel Fiala, Tomáš Mráz]
|
|
|
|
*) When OpenSSL TLS client is connecting without any supported elliptic
|
|
curves and TLS-1.3 protocol is disabled the connection will no longer fail
|
|
if a ciphersuite that does not use a key exchange based on elliptic
|
|
curves can be negotiated.
|
|
[Tomáš Mráz]
|
|
|
|
Changes between 1.1.1n and 1.1.1o [3 May 2022]
|
|
|
|
*) Fixed a bug in the c_rehash script which was not properly sanitising shell
|
|
metacharacters to prevent command injection. This script is distributed
|
|
by some operating systems in a manner where it is automatically executed.
|
|
On such operating systems, an attacker could execute arbitrary commands
|
|
with the privileges of the script.
|
|
|
|
Use of the c_rehash script is considered obsolete and should be replaced
|
|
by the OpenSSL rehash command line tool.
|
|
(CVE-2022-1292)
|
|
[Tomáš Mráz]
|
|
|
|
Changes between 1.1.1m and 1.1.1n [15 Mar 2022]
|
|
|
|
*) Fixed a bug in the BN_mod_sqrt() function that can cause it to loop forever
|
|
for non-prime moduli.
|
|
|
|
Internally this function is used when parsing certificates that contain
|
|
elliptic curve public keys in compressed form or explicit elliptic curve
|
|
parameters with a base point encoded in compressed form.
|
|
|
|
It is possible to trigger the infinite loop by crafting a certificate that
|
|
has invalid explicit curve parameters.
|
|
|
|
Since certificate parsing happens prior to verification of the certificate
|
|
signature, any process that parses an externally supplied certificate may
|
|
thus be subject to a denial of service attack. The infinite loop can also
|
|
be reached when parsing crafted private keys as they can contain explicit
|
|
elliptic curve parameters.
|
|
|
|
Thus vulnerable situations include:
|
|
|
|
- TLS clients consuming server certificates
|
|
- TLS servers consuming client certificates
|
|
- Hosting providers taking certificates or private keys from customers
|
|
- Certificate authorities parsing certification requests from subscribers
|
|
- Anything else which parses ASN.1 elliptic curve parameters
|
|
|
|
Also any other applications that use the BN_mod_sqrt() where the attacker
|
|
can control the parameter values are vulnerable to this DoS issue.
|
|
(CVE-2022-0778)
|
|
[Tomáš Mráz]
|
|
|
|
*) Add ciphersuites based on DHE_PSK (RFC 4279) and ECDHE_PSK (RFC 5489)
|
|
to the list of ciphersuites providing Perfect Forward Secrecy as
|
|
required by SECLEVEL >= 3.
|
|

[Dmitry Belyavskiy, Nicola Tuveri]
|
|
|
|
Changes between 1.1.1l and 1.1.1m [14 Dec 2021]
|
|
|
|
*) Avoid loading of a dynamic engine twice.
|
|
|
|
[Bernd Edlinger]
|
|
|
|
*) Fixed building on Debian with kfreebsd kernels
|
|
|
|
[Mattias Ellert]
|
|
|
|
*) Prioritise DANE TLSA issuer certs over peer certs
|
|
|
|
[Viktor Dukhovni]
|
|
|
|
*) Fixed random API for MacOS prior to 10.12
|
|
|
|
These MacOS versions don't support the CommonCrypto APIs
|
|
|
|
[Lenny Primak]
|
|
|
|
Changes between 1.1.1k and 1.1.1l [24 Aug 2021]
|
|
|
|
*) Fixed an SM2 Decryption Buffer Overflow.
|
|
|
|
In order to decrypt SM2 encrypted data an application is expected to call the
|
|
API function EVP_PKEY_decrypt(). Typically an application will call this
|
|
function twice. The first time, on entry, the "out" parameter can be NULL and,
|
|
on exit, the "outlen" parameter is populated with the buffer size required to
|
|
hold the decrypted plaintext. The application can then allocate a sufficiently
|
|
sized buffer and call EVP_PKEY_decrypt() again, but this time passing a non-NULL
|
|
value for the "out" parameter.
|
|
|
|
A bug in the implementation of the SM2 decryption code means that the
|
|
calculation of the buffer size required to hold the plaintext returned by the
|
|
first call to EVP_PKEY_decrypt() can be smaller than the actual size required by
|
|
the second call. This can lead to a buffer overflow when EVP_PKEY_decrypt() is
|
|
called by the application a second time with a buffer that is too small.
|
|
|
|
A malicious attacker who is able present SM2 content for decryption to an
|
|
application could cause attacker chosen data to overflow the buffer by up to a
|
|
maximum of 62 bytes altering the contents of other data held after the
|
|
buffer, possibly changing application behaviour or causing the application to
|
|
crash. The location of the buffer is application dependent but is typically
|
|
heap allocated.
|
|
(CVE-2021-3711)
|
|
[Matt Caswell]
|
|
|
|
*) Fixed various read buffer overruns processing ASN.1 strings
|
|
|
|
ASN.1 strings are represented internally within OpenSSL as an ASN1_STRING
|
|
structure which contains a buffer holding the string data and a field holding
|
|
the buffer length. This contrasts with normal C strings which are repesented as
|
|
a buffer for the string data which is terminated with a NUL (0) byte.
|
|
|
|
Although not a strict requirement, ASN.1 strings that are parsed using OpenSSL's
|
|
own "d2i" functions (and other similar parsing functions) as well as any string
|
|
whose value has been set with the ASN1_STRING_set() function will additionally
|
|
NUL terminate the byte array in the ASN1_STRING structure.
|
|
|
|
However, it is possible for applications to directly construct valid ASN1_STRING
|
|
structures which do not NUL terminate the byte array by directly setting the
|
|
"data" and "length" fields in the ASN1_STRING array. This can also happen by
|
|
using the ASN1_STRING_set0() function.
|
|
|
|
Numerous OpenSSL functions that print ASN.1 data have been found to assume that
|
|
the ASN1_STRING byte array will be NUL terminated, even though this is not
|
|
guaranteed for strings that have been directly constructed. Where an application
|
|
requests an ASN.1 structure to be printed, and where that ASN.1 structure
|
|
contains ASN1_STRINGs that have been directly constructed by the application
|
|
without NUL terminating the "data" field, then a read buffer overrun can occur.
|
|
|
|
The same thing can also occur during name constraints processing of certificates
|
|
(for example if a certificate has been directly constructed by the application
|
|
instead of loading it via the OpenSSL parsing functions, and the certificate
|
|
contains non NUL terminated ASN1_STRING structures). It can also occur in the
|
|
X509_get1_email(), X509_REQ_get1_email() and X509_get1_ocsp() functions.
|
|
|
|
If a malicious actor can cause an application to directly construct an
|
|
ASN1_STRING and then process it through one of the affected OpenSSL functions
|
|
then this issue could be hit. This might result in a crash (causing a Denial of
|
|
Service attack). It could also result in the disclosure of private memory
|
|
contents (such as private keys, or sensitive plaintext).
|
|
(CVE-2021-3712)
|
|
[Matt Caswell]
|
|
|
|
Changes between 1.1.1j and 1.1.1k [25 Mar 2021]
|
|
|
|
*) Fixed a problem with verifying a certificate chain when using the
|
|
X509_V_FLAG_X509_STRICT flag. This flag enables additional security checks
|
|
of the certificates present in a certificate chain. It is not set by
|
|
default.
|
|
|
|
Starting from OpenSSL version 1.1.1h a check to disallow certificates in
|
|
the chain that have explicitly encoded elliptic curve parameters was added
|
|
as an additional strict check.
|
|
|
|
An error in the implementation of this check meant that the result of a
|
|
previous check to confirm that certificates in the chain are valid CA
|
|
certificates was overwritten. This effectively bypasses the check
|
|
that non-CA certificates must not be able to issue other certificates.
|
|
|
|
If a "purpose" has been configured then there is a subsequent opportunity
|
|
for checks that the certificate is a valid CA. All of the named "purpose"
|
|
values implemented in libcrypto perform this check. Therefore, where
|
|
a purpose is set the certificate chain will still be rejected even when the
|
|
strict flag has been used. A purpose is set by default in libssl client and
|
|
server certificate verification routines, but it can be overridden or
|
|
removed by an application.
|
|
|
|
In order to be affected, an application must explicitly set the
|
|
X509_V_FLAG_X509_STRICT verification flag and either not set a purpose
|
|
for the certificate verification or, in the case of TLS client or server
|
|
applications, override the default purpose.
|
|
(CVE-2021-3450)
|
|
[Tomáš Mráz]
|
|
|
|
*) Fixed an issue where an OpenSSL TLS server may crash if sent a maliciously
|
|
crafted renegotiation ClientHello message from a client. If a TLSv1.2
|
|
renegotiation ClientHello omits the signature_algorithms extension (where
|
|
it was present in the initial ClientHello), but includes a
|
|
signature_algorithms_cert extension then a NULL pointer dereference will
|
|
result, leading to a crash and a denial of service attack.
|
|
|
|
A server is only vulnerable if it has TLSv1.2 and renegotiation enabled
|
|
(which is the default configuration). OpenSSL TLS clients are not impacted
|
|
by this issue.
|
|
(CVE-2021-3449)
|
|
[Peter Kästle and Samuel Sapalski]
|
|
|
|
Changes between 1.1.1i and 1.1.1j [16 Feb 2021]
|
|
|
|
*) Fixed the X509_issuer_and_serial_hash() function. It attempts to
|
|
create a unique hash value based on the issuer and serial number data
|
|
contained within an X509 certificate. However it was failing to correctly
|
|
handle any errors that may occur while parsing the issuer field (which might
|
|
occur if the issuer field is maliciously constructed). This may subsequently
|
|
result in a NULL pointer deref and a crash leading to a potential denial of
|
|
service attack.
|
|
(CVE-2021-23841)
|
|
[Matt Caswell]
|
|
|
|
*) Fixed the RSA_padding_check_SSLv23() function and the RSA_SSLV23_PADDING
|
|
padding mode to correctly check for rollback attacks. This is considered a
|
|
bug in OpenSSL 1.1.1 because it does not support SSLv2. In 1.0.2 this is
|
|
CVE-2021-23839.
|
|
[Matt Caswell]
|
|
|
|
*) Fixed the EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate
|
|
functions. Previously they could overflow the output length argument in some
|
|
cases where the input length is close to the maximum permissable length for
|
|
an integer on the platform. In such cases the return value from the function
|
|
call would be 1 (indicating success), but the output length value would be
|
|
negative. This could cause applications to behave incorrectly or crash.
|
|
(CVE-2021-23840)
|
|
[Matt Caswell]
|
|
|
|
*) Fixed SRP_Calc_client_key so that it runs in constant time. The previous
|
|
implementation called BN_mod_exp without setting BN_FLG_CONSTTIME. This
|
|
could be exploited in a side channel attack to recover the password. Since
|
|
the attack is local host only this is outside of the current OpenSSL
|
|
threat model and therefore no CVE is assigned.
|
|
|
|
Thanks to Mohammed Sabt and Daniel De Almeida Braga for reporting this
|
|
issue.
|
|
[Matt Caswell]
|
|
|
|
Changes between 1.1.1h and 1.1.1i [8 Dec 2020]
|
|
|
|
*) Fixed NULL pointer deref in the GENERAL_NAME_cmp function
|
|
This function could crash if both GENERAL_NAMEs contain an EDIPARTYNAME.
|
|
If an attacker can control both items being compared then this could lead
|
|
to a possible denial of service attack. OpenSSL itself uses the
|
|
GENERAL_NAME_cmp function for two purposes:
|
|
1) Comparing CRL distribution point names between an available CRL and a
|
|
CRL distribution point embedded in an X509 certificate
|
|
2) When verifying that a timestamp response token signer matches the
|
|
timestamp authority name (exposed via the API functions
|
|
TS_RESP_verify_response and TS_RESP_verify_token)
|
|
(CVE-2020-1971)
|
|
[Matt Caswell]
|
|
|
|
*) Add support for Apple Silicon M1 Macs with the darwin64-arm64-cc target.
|
|
[Stuart Carnie]
|
|
|
|
*) The security callback, which can be customised by application code, supports
|
|
the security operation SSL_SECOP_TMP_DH. This is defined to take an EVP_PKEY
|
|
in the "other" parameter. In most places this is what is passed. All these
|
|
places occur server side. However there was one client side call of this
|
|
security operation and it passed a DH object instead. This is incorrect
|
|
according to the definition of SSL_SECOP_TMP_DH, and is inconsistent with all
|
|
of the other locations. Therefore this client side call has been changed to
|
|
pass an EVP_PKEY instead.
|
|
[Matt Caswell]
|
|
|
|
*) In 1.1.1h, an expired trusted (root) certificate was not anymore rejected
|
|
when validating a certificate path. This check is restored in 1.1.1i.
|
|
[David von Oheimb]
|
|
|
|
Changes between 1.1.1g and 1.1.1h [22 Sep 2020]
|
|
|
|
*) Certificates with explicit curve parameters are now disallowed in
|
|
verification chains if the X509_V_FLAG_X509_STRICT flag is used.
|
|
[Tomas Mraz]
|
|
|
|
*) The 'MinProtocol' and 'MaxProtocol' configuration commands now silently
|
|
ignore TLS protocol version bounds when configuring DTLS-based contexts, and
|
|
conversely, silently ignore DTLS protocol version bounds when configuring
|
|
TLS-based contexts. The commands can be repeated to set bounds of both
|
|
types. The same applies with the corresponding "min_protocol" and
|
|
"max_protocol" command-line switches, in case some application uses both TLS
|
|
and DTLS.
|
|
|
|
SSL_CTX instances that are created for a fixed protocol version (e.g.
|
|
TLSv1_server_method()) also silently ignore version bounds. Previously
|
|
attempts to apply bounds to these protocol versions would result in an
|
|
error. Now only the "version-flexible" SSL_CTX instances are subject to
|
|
limits in configuration files in command-line options.
|
|
[Viktor Dukhovni]
|
|
|
|
*) Handshake now fails if Extended Master Secret extension is dropped
|
|
on renegotiation.
|
|
[Tomas Mraz]
|
|
|
|
*) Accidentally, an expired trusted (root) certificate is not anymore rejected
|
|
when validating a certificate path.
|
|
[David von Oheimb]
|
|
|
|
*) The Oracle Developer Studio compiler will start reporting deprecated APIs
|
|
|
|
Changes between 1.1.1f and 1.1.1g [21 Apr 2020]
|
|
|
|
*) Fixed segmentation fault in SSL_check_chain()
|
|
Server or client applications that call the SSL_check_chain() function
|
|
during or after a TLS 1.3 handshake may crash due to a NULL pointer
|
|
dereference as a result of incorrect handling of the
|
|
"signature_algorithms_cert" TLS extension. The crash occurs if an invalid
|
|
or unrecognised signature algorithm is received from the peer. This could
|
|
be exploited by a malicious peer in a Denial of Service attack.
|
|
(CVE-2020-1967)
|
|
[Benjamin Kaduk]
|
|
|
|
*) Added AES consttime code for no-asm configurations
|
|
an optional constant time support for AES was added
|
|
when building openssl for no-asm.
|
|
Enable with: ./config no-asm -DOPENSSL_AES_CONST_TIME
|
|
Disable with: ./config no-asm -DOPENSSL_NO_AES_CONST_TIME
|
|
At this time this feature is by default disabled.
|
|
It will be enabled by default in 3.0.
|
|
[Bernd Edlinger]
|
|
|
|
Changes between 1.1.1e and 1.1.1f [31 Mar 2020]
|
|
|
|
*) Revert the change of EOF detection while reading in libssl to avoid
|
|
regressions in applications depending on the current way of reporting
|
|
the EOF. As the existing method is not fully accurate the change to
|
|
reporting the EOF via SSL_ERROR_SSL is kept on the current development
|
|
branch and will be present in the 3.0 release.
|
|
[Tomas Mraz]
|
|
|
|
*) Revised BN_generate_prime_ex to not avoid factors 3..17863 in p-1
|
|
when primes for RSA keys are computed.
|
|
Since we previously always generated primes == 2 (mod 3) for RSA keys,
|
|
the 2-prime and 3-prime RSA modules were easy to distinguish, since
|
|
N = p*q = 1 (mod 3), but N = p*q*r = 2 (mod 3). Therefore fingerprinting
|
|
2-prime vs. 3-prime RSA keys was possible by computing N mod 3.
|
|
This avoids possible fingerprinting of newly generated RSA modules.
|
|
[Bernd Edlinger]
|
|
|
|
Changes between 1.1.1d and 1.1.1e [17 Mar 2020]
|
|
*) Properly detect EOF while reading in libssl. Previously if we hit an EOF
|
|
while reading in libssl then we would report an error back to the
|
|
application (SSL_ERROR_SYSCALL) but errno would be 0. We now add
|
|
an error to the stack (which means we instead return SSL_ERROR_SSL) and
|
|
therefore give a hint as to what went wrong.
|
|
[Matt Caswell]
|
|
|
|
*) Check that ed25519 and ed448 are allowed by the security level. Previously
|
|
signature algorithms not using an MD were not being checked that they were
|
|
allowed by the security level.
|
|
[Kurt Roeckx]
|
|
|
|
*) Fixed SSL_get_servername() behaviour. The behaviour of SSL_get_servername()
|
|
was not quite right. The behaviour was not consistent between resumption
|
|
and normal handshakes, and also not quite consistent with historical
|
|
behaviour. The behaviour in various scenarios has been clarified and
|
|
it has been updated to make it match historical behaviour as closely as
|
|
possible.
|
|
[Matt Caswell]
|
|
|
|
*) [VMS only] The header files that the VMS compilers include automatically,
|
|
__DECC_INCLUDE_PROLOGUE.H and __DECC_INCLUDE_EPILOGUE.H, use pragmas that
|
|
the C++ compiler doesn't understand. This is a shortcoming in the
|
|
compiler, but can be worked around with __cplusplus guards.
|
|
|
|
C++ applications that use OpenSSL libraries must be compiled using the
|
|
qualifier '/NAMES=(AS_IS,SHORTENED)' to be able to use all the OpenSSL
|
|
functions. Otherwise, only functions with symbols of less than 31
|
|
characters can be used, as the linker will not be able to successfully
|
|
resolve symbols with longer names.
|
|
[Richard Levitte]
|
|
|
|
*) Corrected the documentation of the return values from the EVP_DigestSign*
|
|
set of functions. The documentation mentioned negative values for some
|
|
errors, but this was never the case, so the mention of negative values
|
|
was removed.
|
|
|
|
Code that followed the documentation and thereby check with something
|
|
like 'EVP_DigestSignInit(...) <= 0' will continue to work undisturbed.
|
|
[Richard Levitte]
|
|
|
|
*) Fixed an an overflow bug in the x64_64 Montgomery squaring procedure
|
|
used in exponentiation with 512-bit moduli. No EC algorithms are
|
|
affected. Analysis suggests that attacks against 2-prime RSA1024,
|
|
3-prime RSA1536, and DSA1024 as a result of this defect would be very
|
|
difficult to perform and are not believed likely. Attacks against DH512
|
|
are considered just feasible. However, for an attack the target would
|
|
have to re-use the DH512 private key, which is not recommended anyway.
|
|
Also applications directly using the low level API BN_mod_exp may be
|
|
affected if they use BN_FLG_CONSTTIME.

[Andy Polyakov]
|
|
|
|
*) Added a new method to gather entropy on VMS, based on SYS$GET_ENTROPY.
|
|
The presence of this system service is determined at run-time.
|
|
[Richard Levitte]
|
|
|
|
*) Added newline escaping functionality to a filename when using openssl dgst.
|
|
This output format is to replicate the output format found in the '*sum'
|
|
checksum programs. This aims to preserve backward compatibility.
|
|
[Matt Eaton, Richard Levitte, and Paul Dale]
|
|
|

*) Print all values for a PKCS#12 attribute with 'openssl pkcs12', not just
|

|
|
Changes between 1.1.1c and 1.1.1d [10 Sep 2019]
|
|
|
|
*) Fixed a fork protection issue. OpenSSL 1.1.1 introduced a rewritten random
|
|
number generator (RNG). This was intended to include protection in the
|
|
event of a fork() system call in order to ensure that the parent and child
|
|
processes did not share the same RNG state. However this protection was not
|
|
being used in the default case.
|
|
|
|
A partial mitigation for this issue is that the output from a high
|
|
precision timer is mixed into the RNG state so the likelihood of a parent
|
|
and child process sharing state is significantly reduced.
|
|
|
|
If an application already calls OPENSSL_init_crypto() explicitly using
|
|
OPENSSL_INIT_ATFORK then this problem does not occur at all.
|
|
(CVE-2019-1549)
|
|
[Matthias St. Pierre]
|
|
|
|
*) For built-in EC curves, ensure an EC_GROUP built from the curve name is
|
|
used even when parsing explicit parameters, when loading a serialized key
|
|
or calling `EC_GROUP_new_from_ecpkparameters()`/
|
|
`EC_GROUP_new_from_ecparameters()`.
|
|
This prevents bypass of security hardening and performance gains,
|
|
especially for curves with specialized EC_METHODs.
|
|
By default, if a key encoded with explicit parameters is loaded and later
|
|
serialized, the output is still encoded with explicit parameters, even if
|
|
internally a "named" EC_GROUP is used for computation.
|
|
[Nicola Tuveri]
|
|
|
|
*) Compute ECC cofactors if not provided during EC_GROUP construction. Before
|
|
this change, EC_GROUP_set_generator would accept order and/or cofactor as
|
|
NULL. After this change, only the cofactor parameter can be NULL. It also
|
|
does some minimal sanity checks on the passed order.
|
|
(CVE-2019-1547)
|
|
[Billy Bob Brumley]
|
|
|
|
*) Fixed a padding oracle in PKCS7_dataDecode and CMS_decrypt_set1_pkey.
|
|
An attack is simple, if the first CMS_recipientInfo is valid but the
|
|
second CMS_recipientInfo is chosen ciphertext. If the second
|
|
recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct
|
|
encryption key will be replaced by garbage, and the message cannot be
|
|
decoded, but if the RSA decryption fails, the correct encryption key is
|
|
used and the recipient will not notice the attack.
|
|
As a work around for this potential attack the length of the decrypted
|
|
key must be equal to the cipher default key length, in case the
|
|
certifiate is not given and all recipientInfo are tried out.
|
|
The old behaviour can be re-enabled in the CMS code by setting the
|
|
CMS_DEBUG_DECRYPT flag.
|
|
(CVE-2019-1563)
|
|
[Bernd Edlinger]
|
|
|
|
*) Early start up entropy quality from the DEVRANDOM seed source has been
|
|
improved for older Linux systems. The RAND subsystem will wait for
|
|
/dev/random to be producing output before seeding from /dev/urandom.
|
|
The seeded state is stored for future library initialisations using
|
|
a system global shared memory segment. The shared memory identifier
|
|
can be configured by defining OPENSSL_RAND_SEED_DEVRANDOM_SHM_ID to
|
|
the desired value. The default identifier is 114.
|
|
[Paul Dale]
|
|
|
|
*) Correct the extended master secret constant on EBCDIC systems. Without this
|
|
fix TLS connections between an EBCDIC system and a non-EBCDIC system that
|
|
negotiate EMS will fail. Unfortunately this also means that TLS connections
|
|
between EBCDIC systems with this fix, and EBCDIC systems without this
|
|
fix will fail if they negotiate EMS.
|
|
[Matt Caswell]
|
|
|
|
*) Use Windows installation paths in the mingw builds
|
|
|
|
Mingw isn't a POSIX environment per se, which means that Windows
|
|
paths should be used for installation.
|
|
(CVE-2019-1552)
|
|
[Richard Levitte]
|
|
|
|
*) Changed DH_check to accept parameters with order q and 2q subgroups.
|
|
With order 2q subgroups the bit 0 of the private key is not secret
|
|
but DH_generate_key works around that by clearing bit 0 of the
|
|
private key for those. This avoids leaking bit 0 of the private key.
|
|
[Bernd Edlinger]
|
|
|
|
*) Significantly reduce secure memory usage by the randomness pools.
|
|
[Paul Dale]
|
|
|
|
*) Revert the DEVRANDOM_WAIT feature for Linux systems
|
|
|
|
The DEVRANDOM_WAIT feature added a select() call to wait for the
|
|
/dev/random device to become readable before reading from the
|
|
/dev/urandom device.
|
|
|
|
It turned out that this change had negative side effects on
|
|
performance which were not acceptable. After some discussion it
|
|
was decided to revert this feature and leave it up to the OS
|
|
resp. the platform maintainer to ensure a proper initialization
|
|
during early boot time.
|
|
[Matthias St. Pierre]
|
|
|
|
Changes between 1.1.1b and 1.1.1c [28 May 2019]
|
|
|
|
*) Add build tests for C++. These are generated files that only do one
|
|
thing, to include one public OpenSSL head file each. This tests that
|
|
the public header files can be usefully included in a C++ application.
|
|
|
|
This test isn't enabled by default. It can be enabled with the option
|
|
'enable-buildtest-c++'.
|
|
[Richard Levitte]
|
|
|
|
*) Enable SHA3 pre-hashing for ECDSA and DSA.
|
|
[Patrick Steuer]
|
|
|
|
*) Change the default RSA, DSA and DH size to 2048 bit instead of 1024.
|
|
This changes the size when using the genpkey app when no size is given. It
|
|
fixes an omission in earlier changes that changed all RSA, DSA and DH
|
|
generation apps to use 2048 bits by default.
|
|
[Kurt Roeckx]
|
|
|
|
*) Reorganize the manual pages to consistently have RETURN VALUES,
|
|
EXAMPLES, SEE ALSO and HISTORY come in that order, and adjust
|
|
util/fix-doc-nits accordingly.
|
|
[Paul Yang, Joshua Lock]
|
|
|
|
*) Add the missing accessor EVP_PKEY_get0_engine()
|
|
[Matt Caswell]
|
|
|
|
*) Have apps like 's_client' and 's_server' output the signature scheme
|
|
along with other cipher suite parameters when debugging.
|
|
[Lorinczy Zsigmond]
|
|
|
|
*) Make OPENSSL_config() error agnostic again.
|
|
[Richard Levitte]
|
|
|
|
*) Do the error handling in RSA decryption constant time.
|
|
[Bernd Edlinger]
|
|
|
|
*) Prevent over long nonces in ChaCha20-Poly1305.
|
|
|
|
ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input
|
|
for every encryption operation. RFC 7539 specifies that the nonce value
|
|
(IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length
|
|
and front pads the nonce with 0 bytes if it is less than 12
|
|
bytes. However it also incorrectly allows a nonce to be set of up to 16
|
|
bytes. In this case only the last 12 bytes are significant and any
|
|
additional leading bytes are ignored.
|
|
|
|
It is a requirement of using this cipher that nonce values are
|
|
unique. Messages encrypted using a reused nonce value are susceptible to
|
|
serious confidentiality and integrity attacks. If an application changes
|
|
the default nonce length to be longer than 12 bytes and then makes a
|
|
change to the leading bytes of the nonce expecting the new value to be a
|
|
new unique nonce then such an application could inadvertently encrypt
|
|
messages with a reused nonce.
|
|
|
|
Additionally the ignored bytes in a long nonce are not covered by the
|
|
integrity guarantee of this cipher. Any application that relies on the
|
|
integrity of these ignored leading bytes of a long nonce may be further
|
|
affected. Any OpenSSL internal use of this cipher, including in SSL/TLS,
|
|
is safe because no such use sets such a long nonce value. However user
|
|
applications that use this cipher directly and set a non-default nonce
|
|
length to be longer than 12 bytes may be vulnerable.
|
|
|
|
This issue was reported to OpenSSL on 16th of March 2019 by Joran Dirk
|
|
Greef of Ronomon.
|
|
(CVE-2019-1543)
|
|
[Matt Caswell]
|
|
|
|
*) Add DEVRANDOM_WAIT feature for Linux systems
|
|
|
|
On older Linux systems where the getrandom() system call is not available,
|
|
OpenSSL normally uses the /dev/urandom device for seeding its CSPRNG.
|
|
Contrary to getrandom(), the /dev/urandom device will not block during
|
|
early boot when the kernel CSPRNG has not been seeded yet.
|
|
|
|
To mitigate this known weakness, use select() to wait for /dev/random to
|
|
become readable before reading from /dev/urandom.
|
|
|
|
*) Ensure that SM2 only uses SM3 as digest algorithm
|
|
[Paul Yang]
|
|
|
|
Changes between 1.1.1a and 1.1.1b [26 Feb 2019]
|
|
|
|
*) Added SCA hardening for modular field inversion in EC_GROUP through
|
|
a new dedicated field_inv() pointer in EC_METHOD.
|
|
This also addresses a leakage affecting conversions from projective
|
|
to affine coordinates.
|
|
[Billy Bob Brumley, Nicola Tuveri]
|
|
|
|
*) Change the info callback signals for the start and end of a post-handshake
|
|
message exchange in TLSv1.3. In 1.1.1/1.1.1a we used SSL_CB_HANDSHAKE_START
|
|
and SSL_CB_HANDSHAKE_DONE. Experience has shown that many applications get
|
|
confused by this and assume that a TLSv1.2 renegotiation has started. This
|
|
can break KeyUpdate handling. Instead we no longer signal the start and end
|
|
of a post handshake message exchange (although the messages themselves are
|
|
still signalled). This could break some applications that were expecting
|
|
the old signals. However without this KeyUpdate is not usable for many
|
|
applications.
|
|
[Matt Caswell]
|
|
|
|
*) Fix a bug in the computation of the endpoint-pair shared secret used
|
|
by DTLS over SCTP. This breaks interoperability with older versions
|
|
of OpenSSL like OpenSSL 1.1.0 and OpenSSL 1.0.2. There is a runtime
|
|
switch SSL_MODE_DTLS_SCTP_LABEL_LENGTH_BUG (off by default) enabling
|
|
interoperability with such broken implementations. However, enabling
|
|
this switch breaks interoperability with correct implementations.
|
|
|
|
*) Fix a use after free bug in d2i_X509_PUBKEY when overwriting a
|
|
re-used X509_PUBKEY object if the second PUBKEY is malformed.
|
|
[Bernd Edlinger]
|
|
|
|
*) Move strictness check from EVP_PKEY_asn1_new() to EVP_PKEY_asn1_add0().
|
|
[Richard Levitte]
|
|
|
|
*) Remove the 'dist' target and add a tarball building script. The
|
|
'dist' target has fallen out of use, and it shouldn't be
|
|
necessary to configure just to create a source distribution.
|
|
[Richard Levitte]
|
|
|
|
*) Added support for Linux Kernel TLS data-path. The Linux Kernel data-path
|
|
improves application performance by removing data copies and providing
|
|
applications with zero-copy system calls such as sendfile and splice.
|
|
[Boris Pismenny]
|
|
|
|
Changes between 1.1.1 and 1.1.1a [20 Nov 2018]
|
|
|
|
*) Timing vulnerability in DSA signature generation
|
|
|
|
The OpenSSL DSA signature algorithm has been shown to be vulnerable to a
|
|
timing side channel attack. An attacker could use variations in the signing
|
|
algorithm to recover the private key.
|
|
|
|
This issue was reported to OpenSSL on 16th October 2018 by Samuel Weiser.
|
|
(CVE-2018-0734)
|
|
[Paul Dale]
|
|
|
|
*) Timing vulnerability in ECDSA signature generation
|
|
|
|
The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a
|
|
timing side channel attack. An attacker could use variations in the signing
|
|
algorithm to recover the private key.
|
|
|
|
This issue was reported to OpenSSL on 25th October 2018 by Samuel Weiser.
|
|
(CVE-2018-0735)
|
|
[Paul Dale]
|
|
|
|
*) Added EVP_PKEY_ECDH_KDF_X9_63 and ecdh_KDF_X9_63() as replacements for
|
|
the EVP_PKEY_ECDH_KDF_X9_62 KDF type and ECDH_KDF_X9_62(). The old names
|
|
are retained for backwards compatibility.
|
|
[Antoine Salon]
|
|
|
|
*) Fixed the issue that RAND_add()/RAND_seed() silently discards random input
|
|
if its length exceeds 4096 bytes. The limit has been raised to a buffer size
|
|
of two gigabytes and the error handling improved.
|
|
|
|
This issue was reported to OpenSSL by Dr. Falko Strenzke. It has been
|
|
categorized as a normal bug, not a security issue, because the DRBG reseeds
|
|
automatically and is fully functional even without additional randomness
|
|
provided by the application.
|
|
|
|
Changes between 1.1.0i and 1.1.1 [11 Sep 2018]
|
|
|
|
*) Add a new ClientHello callback. Provides a callback interface that gives
|
|
the application the ability to adjust the nascent SSL object at the
|
|
earliest stage of ClientHello processing, immediately after extensions have
|
|
been collected but before they have been processed. In particular, this
|
|
callback can adjust the supported TLS versions in response to the contents
|
|
of the ClientHello
|
|
[Benjamin Kaduk]
|
|
|
|
*) Add SM2 base algorithm support.
|
|
[Jack Lloyd]
|
|
|
|
*) s390x assembly pack: add (improved) hardware-support for the following
|
|
cryptographic primitives: sha3, shake, aes-gcm, aes-ccm, aes-ctr, aes-ofb,
|
|
aes-cfb/cfb8, aes-ecb.
|
|
[Patrick Steuer]
|
|
|
|
*) Make EVP_PKEY_asn1_new() a bit stricter about its input. A NULL pem_str
|
|
parameter is no longer accepted, as it leads to a corrupt table. NULL
|
|
pem_str is reserved for alias entries only.
|
|
[Richard Levitte]
|
|
|
|
*) Use the new ec_scalar_mul_ladder scaffold to implement a specialized ladder
|
|
step for prime curves. The new implementation is based on formulae from
|
|
differential addition-and-doubling in homogeneous projective coordinates
|
|
from Izu-Takagi "A fast parallel elliptic curve multiplication resistant
|
|
against side channel attacks" and Brier-Joye "Weierstrass Elliptic Curves
|
|
and Side-Channel Attacks" Eq. (8) for y-coordinate recovery, modified
|
|
to work in projective coordinates.
|
|
[Billy Bob Brumley, Nicola Tuveri]
|
|
|
|
*) Change generating and checking of primes so that the error rate of not
|
|
being prime depends on the intended use based on the size of the input.
|
|
For larger primes this will result in more rounds of Miller-Rabin.
|
|
The maximal error rate for primes with more than 1080 bits is lowered
|
|
to 2^-128.
|
|
[Kurt Roeckx, Annie Yousar]
|
|
|
|
*) Increase the number of Miller-Rabin rounds for DSA key generating to 64.
|
|
[Kurt Roeckx]
|
|
|
|
*) The 'tsget' script is renamed to 'tsget.pl', to avoid confusion when
|
|
moving between systems, and to avoid confusion when a Windows build is
|
|
done with mingw vs with MSVC. For POSIX installs, there's still a
|
|
symlink or copy named 'tsget' to avoid that confusion as well.
|
|
[Richard Levitte]
|
|
|
|
*) Revert blinding in ECDSA sign and instead make problematic addition
|
|
length-invariant. Switch even to fixed-length Montgomery multiplication.
|
|
[Andy Polyakov]
|
|
|
|
*) Use the new ec_scalar_mul_ladder scaffold to implement a specialized ladder
|
|
step for binary curves. The new implementation is based on formulae from
|
|
differential addition-and-doubling in mixed Lopez-Dahab projective
|
|
coordinates, modified to independently blind the operands.
|
|
[Billy Bob Brumley, Sohaib ul Hassan, Nicola Tuveri]
|
|
|
|
*) Add a scaffold to optionally enhance the Montgomery ladder implementation
|
|
for `ec_scalar_mul_ladder` (formerly `ec_mul_consttime`) allowing
|
|
EC_METHODs to implement their own specialized "ladder step", to take
|
|
advantage of more favorable coordinate systems or more efficient
|
|
differential addition-and-doubling algorithms.
|
|
[Billy Bob Brumley, Sohaib ul Hassan, Nicola Tuveri]
|
|
|
|
*) Modified the random device based seed sources to keep the relevant
|
|
file descriptors open rather than reopening them on each access.
|
|
This allows such sources to operate in a chroot() jail without
|
|
the associated device nodes being available. This behaviour can be
|
|
controlled using RAND_keep_random_devices_open().
|
|
[Paul Dale]
|
|
|
|
*) Numerous side-channel attack mitigations have been applied. This may have
|
|
performance impacts for some algorithms for the benefit of improved
|
|
security. Specific changes are noted in this change log by their respective
|
|
authors.
|
|
[Matt Caswell]
|
|
|
|
*) AIX shared library support overhaul. Switch to AIX "natural" way of
|
|
handling shared libraries, which means collecting shared objects of
|
|
different versions and bitnesses in one common archive. This allows to
|
|
mitigate conflict between 1.0 and 1.1 side-by-side installations. It
|
|
doesn't affect the way 3rd party applications are linked, only how
|
|
multi-version installation is managed.
|
|
[Andy Polyakov]
|
|
|
|
*) Make ec_group_do_inverse_ord() more robust and available to other
|
|
EC cryptosystems, so that irrespective of BN_FLG_CONSTTIME, SCA
|
|
mitigations are applied to the fallback BN_mod_inverse().
|
|
When using this function rather than BN_mod_inverse() directly, new
|
|
EC cryptosystem implementations are then safer-by-default.
|
|
[Billy Bob Brumley]
|
|
|
|
*) Add coordinate blinding for EC_POINT and implement projective
|
|
coordinate blinding for generic prime curves as a countermeasure to
|
|
chosen point SCA attacks.
|
|
[Sohaib ul Hassan, Nicola Tuveri, Billy Bob Brumley]
|
|
|
|
*) Add blinding to ECDSA and DSA signatures to protect against side channel
|
|
attacks discovered by Keegan Ryan (NCC Group).
|
|
[Matt Caswell]
|
|
|
|
*) Enforce checking in the pkeyutl command line app to ensure that the input
|
|
length does not exceed the maximum supported digest length when performing
|
|
a sign, verify or verifyrecover operation.
|
|
[Matt Caswell]
|
|
|
|
*) SSL_MODE_AUTO_RETRY is enabled by default. Applications that use blocking
|
|
I/O in combination with something like select() or poll() will hang. This
|
|
can be turned off again using SSL_CTX_clear_mode().
|
|
Many applications do not properly handle non-application data records, and
|
|
TLS 1.3 sends more of such records. Setting SSL_MODE_AUTO_RETRY works
|
|
around the problems in those applications, but can also break some.
|
|
It's recommended to read the manpages about SSL_read(), SSL_write(),
|
|
SSL_get_error(), SSL_shutdown(), SSL_CTX_set_mode() and
|
|
SSL_CTX_set_read_ahead() again.
|
|
[Kurt Roeckx]
|
|
|
|
*) When unlocking a pass phrase protected PEM file or PKCS#8 container, we
|
|
now allow empty (zero character) pass phrases.
|
|
[Richard Levitte]
|
|
|
|
*) Apply blinding to binary field modular inversion and remove patent
|
|
pending (OPENSSL_SUN_GF2M_DIV) BN_GF2m_mod_div implementation.
|
|
[Billy Bob Brumley]
|
|
|
|
*) Deprecate ec2_mult.c and unify scalar multiplication code paths for
|
|
binary and prime elliptic curves.
|
|
[Billy Bob Brumley]
|
|
|
|
*) Remove ECDSA nonce padding: EC_POINT_mul is now responsible for
|
|
constant time fixed point multiplication.
|
|
[Billy Bob Brumley]
|
|
|
|
*) Revise elliptic curve scalar multiplication with timing attack
|
|
defenses: ec_wNAF_mul redirects to a constant time implementation
|
|
when computing fixed point and variable point multiplication (which
|
|
in OpenSSL are mostly used with secret scalars in keygen, sign,
|
|
ECDH derive operations).
|
|
[Billy Bob Brumley, Nicola Tuveri, Cesar Pereida García,
|
|
Sohaib ul Hassan]
|
|
|
|
*) Updated CONTRIBUTING
|
|
[Rich Salz]
|
|
|
|
*) Updated DRBG / RAND to request nonce and additional low entropy
|
|
randomness from the system.
|
|
[Matthias St. Pierre]
|
|
|
|
*) Updated 'openssl rehash' to use OpenSSL consistent default.
|
|
[Richard Levitte]
|
|
|
|
*) Moved the load of the ssl_conf module to libcrypto, which helps
|
|
loading engines that libssl uses before libssl is initialised.
|
|
[Matt Caswell]
|
|
|
|
*) Added EVP_PKEY_sign() and EVP_PKEY_verify() for EdDSA
|
|
[Matt Caswell]
|
|
|
|
*) Fixed X509_NAME_ENTRY_set to get multi-valued RDNs right in all cases.
|
|
[Ingo Schwarze, Rich Salz]
|
|
|
|
*) Added output of accepting IP address and port for 'openssl s_server'
|
|
[Richard Levitte]
|
|
|
|
*) Added a new API for TLSv1.3 ciphersuites:
|
|
SSL_CTX_set_ciphersuites()
|
|
SSL_set_ciphersuites()
|
|
[Matt Caswell]
|
|
|
|
*) Memory allocation failures consistently add an error to the error
|
|
stack.
|
|
[Rich Salz]
|
|
|
|
*) Don't use OPENSSL_ENGINES and OPENSSL_CONF environment values
|
|
in libcrypto when run as setuid/setgid.
|
|
[Bernd Edlinger]
|
|
|
|
*) Load any config file by default when libssl is used.
|
|
[Matt Caswell]
|
|
|
|
*) Added new public header file <openssl/rand_drbg.h> and documentation
|
|
for the RAND_DRBG API. See manual page RAND_DRBG(7) for an overview.

[Matthias St. Pierre]
|
|
|
|
*) QNX support removed (cannot find contributors to get their approval
|
|
for the license change).
|
|
[Rich Salz]
|
|
|
|
*) TLSv1.3 replay protection for early data has been implemented. See the
|
|
SSL_read_early_data() man page for further details.
|
|
[Matt Caswell]
|
|
|
|
*) Separated TLSv1.3 ciphersuite configuration out from TLSv1.2 ciphersuite
|
|
configuration. TLSv1.3 ciphersuites are not compatible with TLSv1.2 and
|
|
below. Similarly TLSv1.2 ciphersuites are not compatible with TLSv1.3.
|
|
In order to avoid issues where legacy TLSv1.2 ciphersuite configuration
|
|
would otherwise inadvertently disable all TLSv1.3 ciphersuites the
|
|
configuration has been separated out. See the ciphers man page or the
|
|
SSL_CTX_set_ciphersuites() man page for more information.
|
|
[Matt Caswell]
|
|
|
|
*) On POSIX (BSD, Linux, ...) systems the ocsp(1) command running
|
|
in responder mode now supports the new "-multi" option, which
|
|
spawns the specified number of child processes to handle OCSP
|
|
requests. The "-timeout" option now also limits the OCSP
|
|
responder's patience to wait to receive the full client request
|
|
on a newly accepted connection. Child processes are respawned
|
|
as needed, and the CA index file is automatically reloaded
|
|
when changed. This makes it possible to run the "ocsp" responder
|
|
as a long-running service, making the OpenSSL CA somewhat more
|
|
feature-complete. In this mode, most diagnostic messages logged
|
|
after entering the event loop are logged via syslog(3) rather than
|
|
written to stderr.
|
|
[Viktor Dukhovni]
|
|
|
|
*) Added support for X448 and Ed448. Heavily based on original work by
|
|
Mike Hamburg.
|
|
[Matt Caswell]
|
|
|
|
*) Extend OSSL_STORE with capabilities to search and to narrow the set of
|
|
objects loaded. This adds the functions OSSL_STORE_expect() and
|
|
OSSL_STORE_find() as well as needed tools to construct searches and
|
|
get the search data out of them.
|
|
[Richard Levitte]
|
|
|
|
*) Support for TLSv1.3 added. Note that users upgrading from an earlier
|
|
version of OpenSSL should review their configuration settings to ensure
|
|
that they are still appropriate for TLSv1.3. For further information see:
|
|
https://wiki.openssl.org/index.php/TLS1.3
|
|
[Matt Caswell]
|
|
|
|
*) Grand redesign of the OpenSSL random generator
|
|
|
|
The default RAND method now utilizes an AES-CTR DRBG according to
|
|
NIST standard SP 800-90Ar1. The new random generator is essentially
|
|
a port of the default random generator from the OpenSSL FIPS 2.0
|
|
object module. It is a hybrid deterministic random bit generator
|
|
using an AES-CTR bit stream and which seeds and reseeds itself
|
|
automatically using trusted system entropy sources.
|
|
|
|
Some of its new features are:
|
|
o Support for multiple DRBG instances with seed chaining.
|
|
o The default RAND method makes use of a DRBG.
|
|
o There is a public and private DRBG instance.
|
|
o The DRBG instances are fork-safe.
|
|
o Keep all global DRBG instances on the secure heap if it is enabled.
|
|
o The public and private DRBG instance are per thread for lock free
|
|
operation
|
|
[Paul Dale, Benjamin Kaduk, Kurt Roeckx, Rich Salz, Matthias St. Pierre]
|
|
|
|
*) Changed Configure so it only says what it does and doesn't dump
|
|
so much data. Instead, ./configdata.pm should be used as a script
|
|
to display all sorts of configuration data.
|
|
[Richard Levitte]
|
|
|
|
*) Added processing of "make variables" to Configure.
|
|
[Richard Levitte]
|
|
|
|
*) Added SHA512/224 and SHA512/256 algorithm support.
|
|
[Paul Dale]
|
|
|
|
*) The last traces of Netware support, first removed in 1.1.0, have
|
|
now been removed.
|
|
[Rich Salz]
|
|
|
|
*) Get rid of Makefile.shared, and in the process, make the processing
|
|
of certain files (rc.obj, or the .def/.map/.opt files produced from
|
|
the ordinal files) more visible and hopefully easier to trace and
|
|
debug (or make silent).
|
|
[Richard Levitte]
|
|
|
|
*) Make it possible to have environment variable assignments as
|
|
arguments to config / Configure.
|
|
[Richard Levitte]
|
|
|
|
*) Add multi-prime RSA (RFC 8017) support.

*) Add 'Maximum Fragment Length' TLS extension negotiation and support
|
|
as documented in RFC6066.
|
|
Based on a patch from Tomasz Moń
|
|
[Filipe Raimundo da Silva]
|
|

*) Reimplement -newreq-nodes and ERR_error_string_n; the
|
|
original author does not agree with the license change.
|
|
[Rich Salz]
|
|
|
|
*) Add ARIA AEAD TLS support.
|
|
[Jon Spillett]
|
|
|
|
*) Some macro definitions to support VS6 have been removed. Visual
|
|
Studio 6 has not worked since 1.1.0
|
|
[Rich Salz]
|
|
|
|
*) Add ERR_clear_last_mark(), to allow callers to clear the last mark
|
|
without clearing the errors.
|
|
[Richard Levitte]
|
|
|
|
*) Add "atfork" functions. If building on a system that without
|
|
pthreads, see doc/man3/OPENSSL_fork_prepare.pod for application
|
|
requirements. The RAND facility now uses/requires this.
|
|
[Rich Salz]
|
|
|
|
*) Add SHA3.
|
|
[Andy Polyakov]
|
|
|
|
*) The UI API becomes a permanent and integral part of libcrypto, i.e.
|
|
not possible to disable entirely. However, it's still possible to
|
|
disable the console reading UI method, UI_OpenSSL() (use UI_null()
|
|
as a fallback).
|
|
|
|
To disable, configure with 'no-ui-console'. 'no-ui' is still
|
|
possible to use as an alias. Check at compile time with the
|
|
macro OPENSSL_NO_UI_CONSOLE. The macro OPENSSL_NO_UI is still
|
|
possible to check and is an alias for OPENSSL_NO_UI_CONSOLE.
|
|
[Richard Levitte]
|
|
|
|
*) Add a STORE module, which implements a uniform and URI based reader of
|
|
stores that can contain keys, certificates, CRLs and numerous other
|
|
objects. The main API is loosely based on a few stdio functions,
|
|
and includes OSSL_STORE_open, OSSL_STORE_load, OSSL_STORE_eof,
|
|
OSSL_STORE_error and OSSL_STORE_close.
|
|
The implementation uses backends called "loaders" to implement arbitrary
|
|
URI schemes. There is one built in "loader" for the 'file' scheme.
|
|
[Richard Levitte]
|
|
|
|
*) Add devcrypto engine. This has been implemented against cryptodev-linux,
|
|
then adjusted to work on FreeBSD 8.4 as well.
|
|
Enable by configuring with 'enable-devcryptoeng'. This is done by default
|
|
on BSD implementations, as cryptodev.h is assumed to exist on all of them.
|
|
[Richard Levitte]
|
|
|
|
*) Module names can prefixed with OSSL_ or OPENSSL_. This affects
|
|
util/mkerr.pl, which is adapted to allow those prefixes, leading to
|
|
error code calls like this:
|
|
|
|
OSSL_FOOerr(OSSL_FOO_F_SOMETHING, OSSL_FOO_R_WHATEVER);
|
|
|
|
With this change, we claim the namespaces OSSL and OPENSSL in a manner
|
|
that can be encoded in C. For the foreseeable future, this will only
|
|
affect new modules.
|
|
[Richard Levitte and Tim Hudson]
|
|
|
|
*) Removed BSD cryptodev engine.
|
|
[Rich Salz]
|
|
|
|
*) Add a build target 'build_all_generated', to build all generated files
|
|
and only that. This can be used to prepare everything that requires
|
|
things like perl for a system that lacks perl and then move everything
|
|
to that system and do the rest of the build there.
|
|
[Richard Levitte]
|
|
|
|
*) In the UI interface, make it possible to duplicate the user data. This
|
|
can be used by engines that need to retain the data for a longer time
|
|
than just the call where this user data is passed.
|
|
[Richard Levitte]
|
|
|
|
*) Ignore the '-named_curve auto' value for compatibility of applications
|
|
with OpenSSL 1.0.2.
|
|
[Tomas Mraz <tmraz@fedoraproject.org>]
|
|
|
|
*) Fragmented SSL/TLS alerts are no longer accepted. An alert message is 2
|
|
bytes long. In theory it is permissible in SSLv3 - TLSv1.2 to fragment such
|
|
alerts across multiple records (some of which could be empty). In practice
|
|
it make no sense to send an empty alert record, or to fragment one. TLSv1.3
|
|
prohibits this altogether and other libraries (BoringSSL, NSS) do not
|
|
support this at all. Supporting it adds significant complexity to the
|
|
record layer, and its removal is unlikely to cause interoperability
|
|
issues.
|
|
[Matt Caswell]
|
|
|
|
*) Add the ASN.1 types INT32, UINT32, INT64, UINT64 and variants prefixed
|
|
with Z. These are meant to replace LONG and ZLONG and to be size safe.
|
|
The use of LONG and ZLONG is discouraged and scheduled for deprecation
|
|
in OpenSSL 1.2.0.
|
|
[Richard Levitte]
|
|
|
|
*) Add the 'z' and 'j' modifiers to BIO_printf() et al formatting string,
|
|
'z' is to be used for [s]size_t, and 'j' - with [u]int64_t.
|
|
[Richard Levitte, Andy Polyakov]
|
|
|
|
*) Add EC_KEY_get0_engine(), which does for EC_KEY what RSA_get0_engine()
|
|
does for RSA, etc.
|
|
[Richard Levitte]
|
|
|
|
*) Have 'config' recognise 64-bit mingw and choose 'mingw64' as the target
|
|
platform rather than 'mingw'.
|
|
[Richard Levitte]
|
|
|
|
*) The functions X509_STORE_add_cert and X509_STORE_add_crl return
|
|
success if they are asked to add an object which already exists
|
|
in the store. This change cascades to other functions which load
|
|
certificates and CRLs.
|
|
[Paul Dale]
|
|
|
|
*) x86_64 assembly pack: annotate code with DWARF CFI directives to
|
|
facilitate stack unwinding even from assembly subroutines.
|
|
[Andy Polyakov]
|
|
|
|
*) Remove VAX C specific definitions of OPENSSL_EXPORT, OPENSSL_EXTERN.
|
|
Also remove OPENSSL_GLOBAL entirely, as it became a no-op.
|
|
[Richard Levitte]
|
|
|
|
*) Remove the VMS-specific reimplementation of gmtime from crypto/o_times.c.
|
|
VMS C's RTL has a fully up to date gmtime() and gmtime_r() since V7.1,
|
|
which is the minimum version we support.
|
|
[Richard Levitte]
|
|
|
|
*) Certificate time validation (X509_cmp_time) enforces stricter
|
|
compliance with RFC 5280. Fractional seconds and timezone offsets
|
|
are no longer allowed.
|
|
[Emilia Käsper]
|
|
|
|
*) Add support for ARIA
|
|
[Paul Dale]
|
|
|
|
*) s_client will now send the Server Name Indication (SNI) extension by
|
|
default unless the new "-noservername" option is used. The server name is
|
|
based on the host provided to the "-connect" option unless overridden by
|
|
using "-servername".
|
|
[Matt Caswell]
|
|
|
|
*) Add support for SipHash
|
|
[Todd Short]
|
|
|
|
*) OpenSSL now fails if it receives an unrecognised record type in TLS1.0
|
|
or TLS1.1. Previously this only happened in SSLv3 and TLS1.2. This is to
|
|
prevent issues where no progress is being made and the peer continually
|
|
sends unrecognised record types, using up resources processing them.
|
|
[Matt Caswell]
|
|
|
|
*) 'openssl passwd' can now produce SHA256 and SHA512 based output,
|
|
using the algorithm defined in
|
|
https://www.akkadia.org/drepper/SHA-crypt.txt
|
|
[Richard Levitte]
|
|
|
|
*) Heartbeat support has been removed; the ABI is changed for now.
|
|
[Richard Levitte, Rich Salz]
|
|
|
|
*) Support for SSL_OP_NO_ENCRYPT_THEN_MAC in SSL_CONF_cmd.
|
|
[Emilia Käsper]
|
|
|
|
*) The RSA "null" method, which was partially supported to avoid patent
|
|
issues, has been replaced to always returns NULL.

|
|
*) Client DoS due to large DH parameter
|
|
|
|
During key agreement in a TLS handshake using a DH(E) based ciphersuite a
|
|
malicious server can send a very large prime value to the client. This will
|
|
cause the client to spend an unreasonably long period of time generating a
|
|
key for this prime resulting in a hang until the client has finished. This
|
|
could be exploited in a Denial Of Service attack.

|
|
*) Cache timing vulnerability in RSA Key Generation
|
|
|
|
The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to
|
|
a cache timing side channel attack. An attacker with sufficient access to
|
|
mount cache timing attacks during the RSA key generation process could
|
|
recover the private key.

(CVE-2018-0737)
|
|
[Billy Brumley]
|
|
|
|
*) Make EVP_PKEY_asn1_new() a bit stricter about its input. A NULL pem_str
|
|
parameter is no longer accepted, as it leads to a corrupt table. NULL
|
|
pem_str is reserved for alias entries only.
|
|
[Richard Levitte]
|
|
|
|
*) Revert blinding in ECDSA sign and instead make problematic addition
|
|
length-invariant. Switch even to fixed-length Montgomery multiplication.
|
|
[Andy Polyakov]
|
|
|
|
*) Change generating and checking of primes so that the error rate of not
|
|
being prime depends on the intended use based on the size of the input.
|
|
For larger primes this will result in more rounds of Miller-Rabin.
|
|
The maximal error rate for primes with more than 1080 bits is lowered
|
|
to 2^-128.
|
|
[Kurt Roeckx, Annie Yousar]
|
|
|
|
*) Increase the number of Miller-Rabin rounds for DSA key generating to 64.
|
|
[Kurt Roeckx]
|
|
|
|
*) Add blinding to ECDSA and DSA signatures to protect against side channel
|
|
attacks discovered by Keegan Ryan (NCC Group).
|
|
[Matt Caswell]
|
|
|
|
*) When unlocking a pass phrase protected PEM file or PKCS#8 container, we
|
|
now allow empty (zero character) pass phrases.
|
|
[Richard Levitte]
|
|
|
|
*) Certificate time validation (X509_cmp_time) enforces stricter

are no longer allowed.
|
|
[Emilia Käsper]
|
|
|
|
*) Fixed a text canonicalisation bug in CMS
|
|
|
|
Where a CMS detached signature is used with text content the text goes
|
|
through a canonicalisation process first prior to signing or verifying a
|
|
signature. This process strips trailing space at the end of lines, converts
|
|
line terminators to CRLF and removes additional trailing line terminators
|
|
at the end of a file. A bug in the canonicalisation process meant that
|
|
some characters, such as form-feed, were incorrectly treated as whitespace
|
|
and removed. This is contrary to the specification (RFC5485). This fix
|
|
could mean that detached text data signed with an earlier version of
|
|
OpenSSL 1.1.0 may fail to verify using the fixed version, or text data
|
|
signed with a fixed OpenSSL may fail to verify with an earlier version of
|
|
OpenSSL 1.1.0. A workaround is to only verify the canonicalised text data
|
|
and use the "-binary" flag (for the "cms" command line application) or set
|
|
the SMIME_BINARY/PKCS7_BINARY/CMS_BINARY flags (if using CMS_verify()).

*) Constructed ASN.1 types with a recursive definition could exceed the stack
|
|
|
|
Constructed ASN.1 types with a recursive definition (such as can be found
|
|
in PKCS7) could eventually exceed the stack given malicious input with
|
|
excessive recursion. This could result in a Denial Of Service attack. There
|
|
are no such structures used within SSL/TLS that come from untrusted sources
|
|
so this is considered safe.

[Matt Caswell]
|
|
|
|
*) Incorrect CRYPTO_memcmp on HP-UX PA-RISC
|
|
|
|
Because of an implementation bug the PA-RISC CRYPTO_memcmp function is
|
|
effectively reduced to only comparing the least significant bit of each
|
|
byte. This allows an attacker to forge messages that would be considered as
|
|
authenticated in an amount of tries lower than that guaranteed by the
|
|
security claims of the scheme. The module can only be compiled by the
|
|
HP-UX assembler, so that only HP-UX PA-RISC targets are affected.

|
|
*) Add a build target 'build_all_generated', to build all generated files

|
|
[Richard Levitte]
|
|
|
|
*) Backport SSL_OP_NO_RENGOTIATION
|
|
|
|
OpenSSL 1.0.2 and below had the ability to disable renegotiation using the
|
|
(undocumented) SSL3_FLAGS_NO_RENEGOTIATE_CIPHERS flag. Due to the opacity
|
|
changes this is no longer possible in 1.1.0. Therefore the new
|
|
SSL_OP_NO_RENEGOTIATION option from 1.1.1-dev has been backported to
|
|
1.1.0 to provide equivalent functionality.
|
|
|
|
Note that if an application built against 1.1.0h headers (or above) is run
|
|
using an older version of 1.1.0 (prior to 1.1.0h) then the option will be
|
|
accepted but nothing will happen, i.e. renegotiation will not be prevented.
|
|
[Matt Caswell]

[Rich Salz]
|
|
|
|
*) rsaz_1024_mul_avx2 overflow bug on x86_64
|
|
|
|
There is an overflow bug in the AVX2 Montgomery multiplication procedure
|
|
used in exponentiation with 1024-bit moduli. No EC algorithms are affected.
|
|
Analysis suggests that attacks against RSA and DSA as a result of this
|
|
defect would be very difficult to perform and are not believed likely.
|
|
Attacks against DH1024 are considered just feasible, because most of the
|
|
work necessary to deduce information about a private key may be performed
|
|
offline. The amount of resources required for such an attack would be
|
|
significant. However, for an attack on TLS to be meaningful, the server
|
|
would have to share the DH1024 private key among multiple clients, which is
|
|
no longer an option since CVE-2016-0701.
|
|
|
|
This only affects processors that support the AVX2 but not ADX extensions
|
|
like Intel Haswell (4th generation).
|
|
|
|
This issue was reported to OpenSSL by David Benjamin (Google). The issue
|

*) bn_sqrx8x_internal carry bug on x86_64
|
|
|
|
There is a carry propagating bug in the x86_64 Montgomery squaring
|
|
procedure. No EC algorithms are affected. Analysis suggests that attacks
|
|
against RSA and DSA as a result of this defect would be very difficult to
|
|
perform and are not believed likely. Attacks against DH are considered just
|
|
feasible (although very difficult) because most of the work necessary to
|
|
deduce information about a private key may be performed offline. The amount
|
|
of resources required for such an attack would be very significant and
|
|
likely only accessible to a limited number of attackers. An attacker would
|
|
additionally need online access to an unpatched system using the target
|
|
private key in a scenario with persistent DH parameters and a private
|
|
key that is shared between multiple clients.
|
|
|
|
This only affects processors that support the BMI1, BMI2 and ADX extensions
|
|
like Intel Broadwell (5th generation) and later or AMD Ryzen.

|
|
|
|
If an X.509 certificate has a malformed IPAddressFamily extension,

Changes between 1.1.0d and 1.1.0e [16 Feb 2017]
|
|
|
|
*) Encrypt-Then-Mac renegotiation crash
|
|
|
|
During a renegotiation handshake if the Encrypt-Then-Mac extension is
|
|
negotiated where it was not in the original handshake (or vice-versa) then
|
|
this can cause OpenSSL to crash (dependant on ciphersuite). Both clients
|
|
and servers are affected.
|
|
|
|
This issue was reported to OpenSSL by Joe Orton (Red Hat).

|
|
|
|
*) Truncated packet could crash via OOB read
|
|
|
|
If one side of an SSL/TLS path is running on a 32-bit host and a specific
|
|
cipher is being used, then a truncated packet can cause that host to
|
|
perform an out-of-bounds read, usually resulting in a crash.

|
|
|
|
*) Bad (EC)DHE parameters cause a client crash
|
|
|
|
If a malicious server supplies bad parameters for a DHE or ECDHE key
|
|
exchange then this can result in the client attempting to dereference a
|
|
NULL pointer leading to a client crash. This could be exploited in a Denial
|
|
of Service attack.

|
|
|
|
*) BN_mod_exp may produce incorrect results on x86_64
|
|
|
|
There is a carry propagating bug in the x86_64 Montgomery squaring
|
|
procedure. No EC algorithms are affected. Analysis suggests that attacks
|
|
against RSA and DSA as a result of this defect would be very difficult to
|
|
perform and are not believed likely. Attacks against DH are considered just
|
|
feasible (although very difficult) because most of the work necessary to
|
|
deduce information about a private key may be performed offline. The amount
|
|
of resources required for such an attack would be very significant and
|
|
likely only accessible to a limited number of attackers. An attacker would
|
|
additionally need online access to an unpatched system using the target
|
|
private key in a scenario with persistent DH parameters and a private
|
|
key that is shared between multiple clients. For example this can occur by
|
|
default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very
|
|
similar to CVE-2015-3193 but must be treated as a separate problem.
|
|
|
|
This issue was reported to OpenSSL by the OSS-Fuzz project.

|
|
|
|
*) ChaCha20/Poly1305 heap-buffer-overflow
|
|
|
|
TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to
|
|
a DoS attack by corrupting larger payloads. This can result in an OpenSSL
|
|
crash. This issue is not considered to be exploitable beyond a DoS.

|
[Richard Levitte]
|
|
|
|
*) CMS Null dereference
|
|
|
|
Applications parsing invalid CMS structures can crash with a NULL pointer
|
|
dereference. This is caused by a bug in the handling of the ASN.1 CHOICE
|
|
type in OpenSSL 1.1.0 which can result in a NULL value being passed to the
|
|
structure callback if an attempt is made to free certain invalid encodings.
|
|
Only CHOICE structures using a callback which do not handle NULL value are
|
|
affected.
|
|
|
|
This issue was reported to OpenSSL by Tyler Nighswander of ForAllSecure.

(CVE-2016-7053)
|
|
[Stephen Henson]
|
|
|
|
*) Montgomery multiplication may produce incorrect results
|
|
|
|
There is a carry propagating bug in the Broadwell-specific Montgomery
|
|
multiplication procedure that handles input lengths divisible by, but
|
|
longer than 256 bits. Analysis suggests that attacks against RSA, DSA
|
|
and DH private keys are impossible. This is because the subroutine in
|
|
question is not used in operations with the private key itself and an input
|
|
of the attacker's direct choice. Otherwise the bug can manifest itself as
|
|
transient authentication and key negotiation failures or reproducible
|
|
erroneous outcome of public-key operations with specially crafted input.
|
|
Among EC algorithms only Brainpool P-512 curves are affected and one
|
|
presumably can attack ECDH key negotiation. Impact was not analyzed in
|
|
detail, because pre-requisites for attack are considered unlikely. Namely
|
|
multiple clients have to choose the curve in question and the server has to
|
|
share the private key among them, neither of which is default behaviour.
|
|
Even then only clients that chose the curve will be affected.
|
|
|
|
This issue was publicly reported as transient failures and was not
|
|
initially recognized as a security issue. Thanks to Richard Morgan for
|
|
providing reproducible case.

*) Removed automatic addition of RPATH in shared libraries and executables,
|
|
as this was a remainder from OpenSSL 1.0.x and isn't needed any more.

Changes between 1.1.0a and 1.1.0b [26 Sep 2016]
|
|
|
|
*) Fix Use After Free for large message sizes
|
|
|
|
The patch applied to address CVE-2016-6307 resulted in an issue where if a
|
|
message larger than approx 16k is received then the underlying buffer to
|
|
store the incoming message is reallocated and moved. Unfortunately a
|
|
dangling pointer to the old location is left which results in an attempt to
|
|
write to the previously freed location. This is likely to result in a
|
|
crash, however it could potentially lead to execution of arbitrary code.
|
|
|
|
This issue only affects OpenSSL 1.1.0a.
|
|
|
|
This issue was reported to OpenSSL by Robert Święcki.

Changes between 1.1.0 and 1.1.0a [22 Sep 2016]
|
|
|
|
*) OCSP Status Request extension unbounded memory growth
|
|
|
|
A malicious client can send an excessively large OCSP Status Request
|
|
extension. If that client continually requests renegotiation, sending a
|
|
large OCSP Status Request extension each time, then there will be unbounded
|
|
memory growth on the server. This will eventually lead to a Denial Of
|
|
Service attack through memory exhaustion. Servers with a default
|
|
configuration are vulnerable even if they do not support OCSP. Builds using
|
|
the "no-ocsp" build time option are not affected.

[Matt Caswell]
|
|
|
|
*) SSL_peek() hang on empty record
|
|
|
|
OpenSSL 1.1.0 SSL/TLS will hang during a call to SSL_peek() if the peer
|
|
sends an empty record. This could be exploited by a malicious peer in a
|
|
Denial Of Service attack.
|
|
|
|
This issue was reported to OpenSSL by Alex Gaynor.
|
|
(CVE-2016-6305)
|
|
[Matt Caswell]
|
|
|
|
*) Excessive allocation of memory in tls_get_message_header() and
|
|
dtls1_preprocess_fragment()
|
|
|
|
A (D)TLS message includes 3 bytes for its length in the header for the
|
|
message. This would allow for messages up to 16Mb in length. Messages of
|
|
this length are excessive and OpenSSL includes a check to ensure that a
|
|
peer is sending reasonably sized messages in order to avoid too much memory
|
|
being consumed to service a connection. A flaw in the logic of version
|
|
1.1.0 means that memory for the message is allocated too early, prior to
|
|
the excessive message length check. Due to way memory is allocated in
|
|
OpenSSL this could mean an attacker could force up to 21Mb to be allocated
|
|
to service a connection. This could lead to a Denial of Service through
|
|
memory exhaustion. However, the excessive message length check still takes
|
|
place, and this would cause the connection to immediately fail. Assuming
|
|
that the application calls SSL_free() on the failed connection in a timely
|
|
manner then the 21Mb of allocated memory will then be immediately freed
|
|
again. Therefore the excessive memory allocation will be transitory in
|
|
nature. This then means that there is only a security impact if:
|
|
|
|
1) The application does not call SSL_free() in a timely manner in the event
|
|
that the connection fails
|
|
or
|
|
2) The application is working in a constrained environment where there is
|
|
very little free memory
|
|
or
|
|
3) The attacker initiates multiple connection attempts such that there are
|
|
multiple connections in a state where memory has been allocated for the
|
|
connection; SSL_free() has not yet been called; and there is insufficient
|
|
memory to service the multiple requests.
|
|
|
|
Except in the instance of (1) above any Denial Of Service is likely to be
|
|
transitory because as soon as the connection fails the memory is
|
|
subsequently freed again in the SSL_free() call. However there is an
|
|
increased risk during this period of application crashes due to the lack of
|
|
memory - which would then mean a more serious Denial of Service.

|
|
|
|
*) solaris-x86-cc, i.e. 32-bit configuration with vendor compiler,
|
|
had to be removed. Primary reason is that vendor assembler can't
|
|
assemble our modules with -KPIC flag. As result it, assembly
|
|
support, was not even available as option. But its lack means
|
|
lack of side-channel resistant code, which is incompatible with
|
|
security by todays standards. Fortunately gcc is readily available
|
|
prepackaged option, which we firmly point at...

|
|
Changes between 1.0.2h and 1.1.0 [25 Aug 2016]
|
|
|
|
*) Windows command-line tool supports UTF-8 opt-in option for arguments
|
|
and console input. Setting OPENSSL_WIN32_UTF8 environment variable
|
|
(to any value) allows Windows user to access PKCS#12 file generated
|
|
with Windows CryptoAPI and protected with non-ASCII password, as well
|
|
as files generated under UTF-8 locale on Linux also protected with
|
|
non-ASCII password.
|
|
[Andy Polyakov]
|
|
|
|
*) To mitigate the SWEET32 attack (CVE-2016-2183), 3DES cipher suites
|
|
have been disabled by default and removed from DEFAULT, just like RC4.
|
|
See the RC4 item below to re-enable both.
|
|
[Rich Salz]
|
|
|
|
*) The method for finding the storage location for the Windows RAND seed file
|
|
has changed. First we check %RANDFILE%. If that is not set then we check
|
|
the directories %HOME%, %USERPROFILE% and %SYSTEMROOT% in that order. If
|
|
all else fails we fall back to C:\.
|
|
[Matt Caswell]
|
|
|
|
*) The EVP_EncryptUpdate() function has had its return type changed from void
|
|
to int. A return of 0 indicates and error while a return of 1 indicates
|
|
success.
|
|
[Matt Caswell]
|
|
|
|
*) The flags RSA_FLAG_NO_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME and
|
|
DH_FLAG_NO_EXP_CONSTTIME which previously provided the ability to switch
|
|
off the constant time implementation for RSA, DSA and DH have been made
|
|
no-ops and deprecated.
|
|
[Matt Caswell]
|
|
|
|
*) Windows RAND implementation was simplified to only get entropy by
|
|
calling CryptGenRandom(). Various other RAND-related tickets
|
|
were also closed.
|
|
[Joseph Wylie Yandle, Rich Salz]
|
|
|
|
*) The stack and lhash API's were renamed to start with OPENSSL_SK_
|
|
and OPENSSL_LH_, respectively. The old names are available
|
|
with API compatibility. They new names are now completely documented.
|
|
[Rich Salz]
|
|
|
|
*) Unify TYPE_up_ref(obj) methods signature.
|
|
SSL_CTX_up_ref(), SSL_up_ref(), X509_up_ref(), EVP_PKEY_up_ref(),
|
|
X509_CRL_up_ref(), X509_OBJECT_up_ref_count() methods are now returning an
|
|
int (instead of void) like all others TYPE_up_ref() methods.
|
|
So now these methods also check the return value of CRYPTO_atomic_add(),
|
|
and the validity of object reference counter.
|
|
[fdasilvayy@gmail.com]
|
|
|
|
*) With Windows Visual Studio builds, the .pdb files are installed
|
|
alongside the installed libraries and executables. For a static
|
|
library installation, ossl_static.pdb is the associate compiler
|
|
generated .pdb file to be used when linking programs.
|
|
[Richard Levitte]
|
|
|
|
*) Remove openssl.spec. Packaging files belong with the packagers.
|
|
[Richard Levitte]
|
|
|
|
*) Automatic Darwin/OSX configuration has had a refresh, it will now
|
|
recognise x86_64 architectures automatically. You can still decide
|
|
to build for a different bitness with the environment variable
|
|
KERNEL_BITS (can be 32 or 64), for example:
|
|
|
|
KERNEL_BITS=32 ./config
|
|
|
|
[Richard Levitte]
|
|
|
|
*) Change default algorithms in pkcs8 utility to use PKCS#5 v2.0,
|
|
256 bit AES and HMAC with SHA256.
|
|
[Steve Henson]
|
|
|
|
*) Remove support for MIPS o32 ABI on IRIX (and IRIX only).
|
|
[Andy Polyakov]
|
|
|
|
*) Triple-DES ciphers have been moved from HIGH to MEDIUM.
|
|
[Rich Salz]
|
|
|
|
*) To enable users to have their own config files and build file templates,
|
|
Configure looks in the directory indicated by the environment variable
|
|
OPENSSL_LOCAL_CONFIG_DIR as well as the in-source Configurations/
|
|
directory. On VMS, OPENSSL_LOCAL_CONFIG_DIR is expected to be a logical
|
|
name and is used as is.
|
|
[Richard Levitte]
|
|
|
|
*) The following datatypes were made opaque: X509_OBJECT, X509_STORE_CTX,
|
|
X509_STORE, X509_LOOKUP, and X509_LOOKUP_METHOD. The unused type
|
|
X509_CERT_FILE_CTX was removed.
|
|
[Rich Salz]
|
|
|
|
*) "shared" builds are now the default. To create only static libraries use
|
|
the "no-shared" Configure option.
|
|
[Matt Caswell]
|
|
|
|
*) Remove the no-aes, no-hmac, no-rsa, no-sha and no-md5 Configure options.
|
|
All of these option have not worked for some while and are fundamental
|
|
algorithms.
|
|
[Matt Caswell]
|
|
|
|
*) Make various cleanup routines no-ops and mark them as deprecated. Most
|
|
global cleanup functions are no longer required because they are handled
|
|
via auto-deinit (see OPENSSL_init_crypto and OPENSSL_init_ssl man pages).
|
|
Explicitly de-initing can cause problems (e.g. where a library that uses
|
|
OpenSSL de-inits, but an application is still using it). The affected
|
|
functions are CONF_modules_free(), ENGINE_cleanup(), OBJ_cleanup(),
|
|
EVP_cleanup(), BIO_sock_cleanup(), CRYPTO_cleanup_all_ex_data(),
|
|
RAND_cleanup(), SSL_COMP_free_compression_methods(), ERR_free_strings() and
|
|
COMP_zlib_cleanup().
|
|
[Matt Caswell]
|
|
|
|
*) --strict-warnings no longer enables runtime debugging options
|
|
such as REF_DEBUG. Instead, debug options are automatically
|
|
enabled with '--debug' builds.
|
|
[Andy Polyakov, Emilia Käsper]
|
|
|
|
*) Made DH and DH_METHOD opaque. The structures for managing DH objects
|
|
have been moved out of the public header files. New functions for managing
|
|
these have been added.
|
|
[Matt Caswell]
|
|
|
|
*) Made RSA and RSA_METHOD opaque. The structures for managing RSA
|
|
objects have been moved out of the public header files. New
|
|
functions for managing these have been added.
|
|
[Richard Levitte]
|
|
|
|
*) Made DSA and DSA_METHOD opaque. The structures for managing DSA objects
|
|
have been moved out of the public header files. New functions for managing
|
|
these have been added.
|
|
[Matt Caswell]
|
|
|
|
*) Made BIO and BIO_METHOD opaque. The structures for managing BIOs have been
|
|
moved out of the public header files. New functions for managing these
|
|
have been added.
|
|
[Matt Caswell]
|
|
|
|
*) Removed no-rijndael as a config option. Rijndael is an old name for AES.
|
|
[Matt Caswell]
|
|
|
|
*) Removed the mk1mf build scripts.
|
|
[Richard Levitte]
|
|
|
|
*) Headers are now wrapped, if necessary, with OPENSSL_NO_xxx, so
|
|
it is always safe to #include a header now.
|
|
[Rich Salz]
|
|
|
|
*) Removed the aged BC-32 config and all its supporting scripts
|
|
[Richard Levitte]
|
|
|
|
*) Removed support for Ultrix, Netware, and OS/2.
|
|
[Rich Salz]
|
|
|
|
*) Add support for HKDF.
|
|
[Alessandro Ghedini]
|
|
|
|
*) Add support for blake2b and blake2s
|
|
[Bill Cox]
|
|
|
|
*) Added support for "pipelining". Ciphers that have the
|
|
EVP_CIPH_FLAG_PIPELINE flag set have a capability to process multiple
|
|
encryptions/decryptions simultaneously. There are currently no built-in
|
|
ciphers with this property but the expectation is that engines will be able
|
|
to offer it to significantly improve throughput. Support has been extended
|
|
into libssl so that multiple records for a single connection can be
|
|
processed in one go (for >=TLS 1.1).
|
|
[Matt Caswell]
|
|
|
|
*) Added the AFALG engine. This is an async capable engine which is able to
|
|
offload work to the Linux kernel. In this initial version it only supports
|
|
AES128-CBC. The kernel must be version 4.1.0 or greater.
|
|
[Catriona Lucey]
|
|
|
|
*) OpenSSL now uses a new threading API. It is no longer necessary to
|
|
set locking callbacks to use OpenSSL in a multi-threaded environment. There
|
|
are two supported threading models: pthreads and windows threads. It is
|
|
also possible to configure OpenSSL at compile time for "no-threads". The
|
|
old threading API should no longer be used. The functions have been
|
|
replaced with "no-op" compatibility macros.
|
|
[Alessandro Ghedini, Matt Caswell]
|
|
|
|
*) Modify behavior of ALPN to invoke callback after SNI/servername
|
|
callback, such that updates to the SSL_CTX affect ALPN.
|
|
[Todd Short]
|
|
|
|
*) Add SSL_CIPHER queries for authentication and key-exchange.
|
|
[Todd Short]
|
|
|
|
*) Changes to the DEFAULT cipherlist:
|
|
- Prefer (EC)DHE handshakes over plain RSA.
|
|
- Prefer AEAD ciphers over legacy ciphers.
|
|
- Prefer ECDSA over RSA when both certificates are available.
|
|
- Prefer TLSv1.2 ciphers/PRF.
|
|
- Remove DSS, SEED, IDEA, CAMELLIA, and AES-CCM from the
|
|
default cipherlist.
|
|
[Emilia Käsper]
|
|
|
|
*) Change the ECC default curve list to be this, in order: x25519,
|
|
secp256r1, secp521r1, secp384r1.
|
|
[Rich Salz]
|
|
|
|
*) RC4 based libssl ciphersuites are now classed as "weak" ciphers and are
|
|
disabled by default. They can be re-enabled using the
|
|
enable-weak-ssl-ciphers option to Configure.
|
|
[Matt Caswell]
|
|
|
|
*) If the server has ALPN configured, but supports no protocols that the
|
|
client advertises, send a fatal "no_application_protocol" alert.
|
|
This behaviour is SHALL in RFC 7301, though it isn't universally
|
|
implemented by other servers.
|
|
[Emilia Käsper]
|
|
|
|
*) Add X25519 support.
|
|
Add ASN.1 and EVP_PKEY methods for X25519. This includes support
|
|
for public and private key encoding using the format documented in
|
|
draft-ietf-curdle-pkix-02. The corresponding EVP_PKEY method supports
|
|
key generation and key derivation.
|
|
|
|
TLS support complies with draft-ietf-tls-rfc4492bis-08 and uses
|
|
X25519(29).
|
|
[Steve Henson]
|
|
|
|
*) Deprecate SRP_VBASE_get_by_user.
|
|
SRP_VBASE_get_by_user had inconsistent memory management behaviour.
|
|
In order to fix an unavoidable memory leak (CVE-2016-0798),
|
|
SRP_VBASE_get_by_user was changed to ignore the "fake user" SRP
|
|
seed, even if the seed is configured.
|
|
|
|
Users should use SRP_VBASE_get1_by_user instead. Note that in
|
|
SRP_VBASE_get1_by_user, caller must free the returned value. Note
|
|
also that even though configuring the SRP seed attempts to hide
|
|
invalid usernames by continuing the handshake with fake
|
|
credentials, this behaviour is not constant time and no strong
|
|
guarantees are made that the handshake is indistinguishable from
|
|
that of a valid user.
|
|
[Emilia Käsper]
|
|
|
|
*) Configuration change; it's now possible to build dynamic engines
|
|
without having to build shared libraries and vice versa. This
|
|
only applies to the engines in engines/, those in crypto/engine/
|
|
will always be built into libcrypto (i.e. "static").
|
|
|
|
Building dynamic engines is enabled by default; to disable, use
|
|
the configuration option "disable-dynamic-engine".
|
|
|
|
The only requirements for building dynamic engines are the
|
|
presence of the DSO module and building with position independent
|
|
code, so they will also automatically be disabled if configuring
|
|
with "disable-dso" or "disable-pic".
|
|
|
|
The macros OPENSSL_NO_STATIC_ENGINE and OPENSSL_NO_DYNAMIC_ENGINE
|
|
are also taken away from openssl/opensslconf.h, as they are
|
|
irrelevant.
|
|
[Richard Levitte]
|
|
|
|
*) Configuration change; if there is a known flag to compile
|
|
position independent code, it will always be applied on the
|
|
libcrypto and libssl object files, and never on the application
|
|
object files. This means other libraries that use routines from
|
|
libcrypto / libssl can be made into shared libraries regardless
|
|
of how OpenSSL was configured.
|
|
|
|
If this isn't desirable, the configuration options "disable-pic"
|
|
or "no-pic" can be used to disable the use of PIC. This will
|
|
also disable building shared libraries and dynamic engines.
|
|
[Richard Levitte]
|
|
|
|
*) Removed JPAKE code. It was experimental and has no wide use.
|
|
[Rich Salz]
|
|
|
|
*) The INSTALL_PREFIX Makefile variable has been renamed to
|
|
DESTDIR. That makes for less confusion on what this variable
|
|
is for. Also, the configuration option --install_prefix is
|
|
removed.
|
|
[Richard Levitte]
|
|
|
|
*) Heartbeat for TLS has been removed and is disabled by default
|
|
for DTLS; configure with enable-heartbeats. Code that uses the
|
|
old #define's might need to be updated.
|
|
[Emilia Käsper, Rich Salz]
|
|
|
|
*) Rename REF_CHECK to REF_DEBUG.
|
|
[Rich Salz]
|
|
|
|
*) New "unified" build system
|
|
|
|
The "unified" build system is aimed to be a common system for all
|
|
platforms we support. With it comes new support for VMS.
|
|
|
|
This system builds supports building in a different directory tree
|
|
than the source tree. It produces one Makefile (for unix family
|
|
or lookalikes), or one descrip.mms (for VMS).
|
|
|
|
The source of information to make the Makefile / descrip.mms is
|
|
small files called 'build.info', holding the necessary
|
|
information for each directory with source to compile, and a
|
|
template in Configurations, like unix-Makefile.tmpl or
|
|
descrip.mms.tmpl.
|
|
|
|
With this change, the library names were also renamed on Windows
|
|
and on VMS. They now have names that are closer to the standard
|
|
on Unix, and include the major version number, and in certain
|
|
cases, the architecture they are built for. See "Notes on shared
|
|
libraries" in INSTALL.
|
|
|
|
We rely heavily on the perl module Text::Template.
|
|
[Richard Levitte]
|
|
|
|
*) Added support for auto-initialisation and de-initialisation of the library.
|
|
OpenSSL no longer requires explicit init or deinit routines to be called,
|
|
except in certain circumstances. See the OPENSSL_init_crypto() and
|
|
OPENSSL_init_ssl() man pages for further information.
|
|
[Matt Caswell]
|
|
|
|
*) The arguments to the DTLSv1_listen function have changed. Specifically the
|
|
"peer" argument is now expected to be a BIO_ADDR object.
|
|
|
|
*) Rewrite of BIO networking library. The BIO library lacked consistent
|
|
support of IPv6, and adding it required some more extensive
|
|
modifications. This introduces the BIO_ADDR and BIO_ADDRINFO types,
|
|
which hold all types of addresses and chains of address information.
|
|
It also introduces a new API, with functions like BIO_socket,
|
|
BIO_connect, BIO_listen, BIO_lookup and a rewrite of BIO_accept.
|
|
The source/sink BIOs BIO_s_connect, BIO_s_accept and BIO_s_datagram
|
|
have been adapted accordingly.
|
|
[Richard Levitte]
|
|
|
|
*) RSA_padding_check_PKCS1_type_1 now accepts inputs with and without
|
|
the leading 0-byte.
|
|
[Emilia Käsper]
|
|
|
|
*) CRIME protection: disable compression by default, even if OpenSSL is
|
|
compiled with zlib enabled. Applications can still enable compression
|
|
by calling SSL_CTX_clear_options(ctx, SSL_OP_NO_COMPRESSION), or by
|
|
using the SSL_CONF library to configure compression.
|
|
[Emilia Käsper]
|
|
|
|
*) The signature of the session callback configured with
|
|
SSL_CTX_sess_set_get_cb was changed. The read-only input buffer
|
|
was explicitly marked as 'const unsigned char*' instead of
|
|
'unsigned char*'.
|
|
[Emilia Käsper]
|
|
|
|
*) Always DPURIFY. Remove the use of uninitialized memory in the
|
|
RNG, and other conditional uses of DPURIFY. This makes -DPURIFY a no-op.
|
|
[Emilia Käsper]
|
|
|
|
*) Removed many obsolete configuration items, including
|
|
DES_PTR, DES_RISC1, DES_RISC2, DES_INT
|
|
MD2_CHAR, MD2_INT, MD2_LONG
|
|
BF_PTR, BF_PTR2
|
|
IDEA_SHORT, IDEA_LONG
|
|
RC2_SHORT, RC2_LONG, RC4_LONG, RC4_CHUNK, RC4_INDEX
|
|
[Rich Salz, with advice from Andy Polyakov]
|
|
|
|
*) Many BN internals have been moved to an internal header file.
|
|
[Rich Salz with help from Andy Polyakov]
|
|
|
|
*) Configuration and writing out the results from it has changed.
|
|
Files such as Makefile include/openssl/opensslconf.h and are now
|
|
produced through general templates, such as Makefile.in and
|
|
crypto/opensslconf.h.in and some help from the perl module
|
|
Text::Template.
|
|
|
|
Also, the center of configuration information is no longer
|
|
Makefile. Instead, Configure produces a perl module in
|
|
configdata.pm which holds most of the config data (in the hash
|
|
table %config), the target data that comes from the target
|
|
configuration in one of the Configurations/*.conf files (in
|
|
%target).
|
|
[Richard Levitte]
|
|
|
|
*) To clarify their intended purposes, the Configure options
|
|
--prefix and --openssldir change their semantics, and become more
|
|
straightforward and less interdependent.
|
|
|
|
--prefix shall be used exclusively to give the location INSTALLTOP
|
|
where programs, scripts, libraries, include files and manuals are
|
|
going to be installed. The default is now /usr/local.
|
|
|
|
--openssldir shall be used exclusively to give the default
|
|
location OPENSSLDIR where certificates, private keys, CRLs are
|
|
managed. This is also where the default openssl.cnf gets
|
|
installed.
|
|
If the directory given with this option is a relative path, the
|
|
values of both the --prefix value and the --openssldir value will
|
|
be combined to become OPENSSLDIR.
|
|
The default for --openssldir is INSTALLTOP/ssl.
|
|
|
|
Anyone who uses --openssldir to specify where OpenSSL is to be
|
|
installed MUST change to use --prefix instead.
|
|
[Richard Levitte]
|
|
|
|
*) The GOST engine was out of date and therefore it has been removed. An up
|
|
to date GOST engine is now being maintained in an external repository.
|
|
See: https://wiki.openssl.org/index.php/Binaries. Libssl still retains
|
|
support for GOST ciphersuites (these are only activated if a GOST engine
|
|
is present).
|
|
[Matt Caswell]
|
|
|
|
*) EGD is no longer supported by default; use enable-egd when
|
|
configuring.
|
|
[Ben Kaduk and Rich Salz]
|
|
|
|
*) The distribution now has Makefile.in files, which are used to
|
|
create Makefile's when Configure is run. *Configure must be run
|
|
before trying to build now.*
|
|
[Rich Salz]
|
|
|
|
*) The return value for SSL_CIPHER_description() for error conditions
|
|
has changed.
|
|
[Rich Salz]
|
|
|
|
*) Support for RFC6698/RFC7671 DANE TLSA peer authentication.
|
|
|
|
Obtaining and performing DNSSEC validation of TLSA records is
|
|
the application's responsibility. The application provides
|
|
the TLSA records of its choice to OpenSSL, and these are then
|
|
used to authenticate the peer.
|
|
|
|
The TLSA records need not even come from DNS. They can, for
|
|
example, be used to implement local end-entity certificate or
|
|
trust-anchor "pinning", where the "pin" data takes the form
|
|
of TLSA records, which can augment or replace verification
|
|
based on the usual WebPKI public certification authorities.
|
|
[Viktor Dukhovni]
|
|
|
|
*) Revert default OPENSSL_NO_DEPRECATED setting. Instead OpenSSL
|
|
continues to support deprecated interfaces in default builds.
|
|
However, applications are strongly advised to compile their
|
|
source files with -DOPENSSL_API_COMPAT=0x10100000L, which hides
|
|
the declarations of all interfaces deprecated in 0.9.8, 1.0.0
|
|
or the 1.1.0 releases.
|
|
|
|
In environments in which all applications have been ported to
|
|
not use any deprecated interfaces OpenSSL's Configure script
|
|
should be used with the --api=1.1.0 option to entirely remove
|
|
support for the deprecated features from the library and
|
|
unconditionally disable them in the installed headers.
|
|
Essentially the same effect can be achieved with the "no-deprecated"
|
|
argument to Configure, except that this will always restrict
|
|
the build to just the latest API, rather than a fixed API
|
|
version.
|
|
|
|
As applications are ported to future revisions of the API,
|
|
they should update their compile-time OPENSSL_API_COMPAT define
|
|
accordingly, but in most cases should be able to continue to
|
|
compile with later releases.
|
|
|
|
The OPENSSL_API_COMPAT versions for 1.0.0, and 0.9.8 are
|
|
0x10000000L and 0x00908000L, respectively. However those
|
|
versions did not support the OPENSSL_API_COMPAT feature, and
|
|
so applications are not typically tested for explicit support
|
|
of just the undeprecated features of either release.
|
|
[Viktor Dukhovni]
|
|
|
|
*) Add support for setting the minimum and maximum supported protocol.
|
|
It can bet set via the SSL_set_min_proto_version() and
|
|
SSL_set_max_proto_version(), or via the SSL_CONF's MinProtocol and
|
|
MaxProtocol. It's recommended to use the new APIs to disable
|
|
protocols instead of disabling individual protocols using
|
|
SSL_set_options() or SSL_CONF's Protocol. This change also
|
|
removes support for disabling TLS 1.2 in the OpenSSL TLS
|
|
client at compile time by defining OPENSSL_NO_TLS1_2_CLIENT.
|
|
[Kurt Roeckx]
|
|
|
|
*) Support for ChaCha20 and Poly1305 added to libcrypto and libssl.
|
|
[Andy Polyakov]
|
|
|
|
*) New EC_KEY_METHOD, this replaces the older ECDSA_METHOD and ECDH_METHOD
|
|
and integrates ECDSA and ECDH functionality into EC. Implementations can
|
|
now redirect key generation and no longer need to convert to or from
|
|
ECDSA_SIG format.
|
|
|
|
Note: the ecdsa.h and ecdh.h headers are now no longer needed and just
|
|
include the ec.h header file instead.
|
|
[Steve Henson]
|
|
|
|
*) Remove support for all 40 and 56 bit ciphers. This includes all the export
|
|
ciphers who are no longer supported and drops support the ephemeral RSA key
|
|
exchange. The LOW ciphers currently doesn't have any ciphers in it.
|
|
[Kurt Roeckx]
|
|
|
|
*) Made EVP_MD_CTX, EVP_MD, EVP_CIPHER_CTX, EVP_CIPHER and HMAC_CTX
|
|
opaque. For HMAC_CTX, the following constructors and destructors
|
|
were added:
|
|
|
|
HMAC_CTX *HMAC_CTX_new(void);
|
|
void HMAC_CTX_free(HMAC_CTX *ctx);
|
|
|
|
For EVP_MD and EVP_CIPHER, complete APIs to create, fill and
|
|
destroy such methods has been added. See EVP_MD_meth_new(3) and
|
|
EVP_CIPHER_meth_new(3) for documentation.
|
|
|
|
Additional changes:
|
|
1) EVP_MD_CTX_cleanup(), EVP_CIPHER_CTX_cleanup() and
|
|
HMAC_CTX_cleanup() were removed. HMAC_CTX_reset() and
|
|
EVP_MD_CTX_reset() should be called instead to reinitialise
|
|
an already created structure.
|
|
2) For consistency with the majority of our object creators and
|
|
destructors, EVP_MD_CTX_(create|destroy) were renamed to
|
|
EVP_MD_CTX_(new|free). The old names are retained as macros
|
|
for deprecated builds.
|
|
[Richard Levitte]
|
|
|
|
*) Added ASYNC support. Libcrypto now includes the async sub-library to enable
|
|
cryptographic operations to be performed asynchronously as long as an
|
|
asynchronous capable engine is used. See the ASYNC_start_job() man page for
|
|
further details. Libssl has also had this capability integrated with the
|
|
introduction of the new mode SSL_MODE_ASYNC and associated error
|
|
SSL_ERROR_WANT_ASYNC. See the SSL_CTX_set_mode() and SSL_get_error() man
|
|
pages. This work was developed in partnership with Intel Corp.
|
|
[Matt Caswell]
|
|
|
|
*) SSL_{CTX_}set_ecdh_auto() has been removed and ECDH is support is
|
|
always enabled now. If you want to disable the support you should
|
|
exclude it using the list of supported ciphers. This also means that the
|
|
"-no_ecdhe" option has been removed from s_server.
|
|
[Kurt Roeckx]
|
|
|
|
*) SSL_{CTX}_set_tmp_ecdh() which can set 1 EC curve now internally calls
|
|
SSL_{CTX_}set1_curves() which can set a list.
|
|
[Kurt Roeckx]
|
|
|
|
*) Remove support for SSL_{CTX_}set_tmp_ecdh_callback(). You should set the
|
|
curve you want to support using SSL_{CTX_}set1_curves().
|
|
[Kurt Roeckx]
|
|
|
|
*) State machine rewrite. The state machine code has been significantly
|
|
refactored in order to remove much duplication of code and solve issues
|
|
with the old code (see ssl/statem/README for further details). This change
|
|
does have some associated API changes. Notably the SSL_state() function
|
|
has been removed and replaced by SSL_get_state which now returns an
|
|
"OSSL_HANDSHAKE_STATE" instead of an int. SSL_set_state() has been removed
|
|
altogether. The previous handshake states defined in ssl.h and ssl3.h have
|
|
also been removed.
|
|
[Matt Caswell]
|
|
|
|
*) All instances of the string "ssleay" in the public API were replaced
|
|
with OpenSSL (case-matching; e.g., OPENSSL_VERSION for #define's)
|
|
Some error codes related to internal RSA_eay API's were renamed.
|
|
[Rich Salz]
|
|
|
|
*) The demo files in crypto/threads were moved to demo/threads.
|
|
[Rich Salz]
|
|
|
|
*) Removed obsolete engines: 4758cca, aep, atalla, cswift, nuron, gmp,
|
|
sureware and ubsec.
|
|
[Matt Caswell, Rich Salz]
|
|
|
|
*) New ASN.1 embed macro.
|
|
|
|
New ASN.1 macro ASN1_EMBED. This is the same as ASN1_SIMPLE except the
|
|
structure is not allocated: it is part of the parent. That is instead of
|
|
|
|
FOO *x;
|
|
|
|
it must be:
|
|
|
|
FOO x;
|
|
|
|
This reduces memory fragmentation and make it impossible to accidentally
|
|
set a mandatory field to NULL.
|
|
|
|
This currently only works for some fields specifically a SEQUENCE, CHOICE,
|
|
or ASN1_STRING type which is part of a parent SEQUENCE. Since it is
|
|
equivalent to ASN1_SIMPLE it cannot be tagged, OPTIONAL, SET OF or
|
|
SEQUENCE OF.
|
|
[Steve Henson]
|
|
|
|
*) Remove EVP_CHECK_DES_KEY, a compile-time option that never compiled.
|
|
[Emilia Käsper]
|
|
|
|
*) Removed DES and RC4 ciphersuites from DEFAULT. Also removed RC2 although
|
|
in 1.0.2 EXPORT was already removed and the only RC2 ciphersuite is also
|
|
an EXPORT one. COMPLEMENTOFDEFAULT has been updated accordingly to add
|
|
DES and RC4 ciphersuites.
|
|
[Matt Caswell]
|
|
|
|
*) Rewrite EVP_DecodeUpdate (base64 decoding) to fix several bugs.
|
|
This changes the decoding behaviour for some invalid messages,
|
|
though the change is mostly in the more lenient direction, and
|
|
legacy behaviour is preserved as much as possible.
|
|
[Emilia Käsper]
|
|
|
|
*) Fix no-stdio build.
|
|
[ David Woodhouse <David.Woodhouse@intel.com> and also
|
|
Ivan Nestlerode <ivan.nestlerode@sonos.com> ]
|
|
|
|
*) New testing framework
|
|
The testing framework has been largely rewritten and is now using
|
|
perl and the perl modules Test::Harness and an extended variant of
|
|
Test::More called OpenSSL::Test to do its work. All test scripts in
|
|
test/ have been rewritten into test recipes, and all direct calls to
|
|
executables in test/Makefile have become individual recipes using the
|
|
simplified testing OpenSSL::Test::Simple.
|
|
|
|
For documentation on our testing modules, do:
|

|
|

|
|
|
|
[Richard Levitte]
|
|
|
|
*) Revamped memory debug; only -DCRYPTO_MDEBUG and -DCRYPTO_MDEBUG_ABORT
|
|
are used; the latter aborts on memory leaks (usually checked on exit).
|
|
Some undocumented "set malloc, etc., hooks" functions were removed
|
|
and others were changed. All are now documented.
|
|
[Rich Salz]
|
|
|
|
*) In DSA_generate_parameters_ex, if the provided seed is too short,
|
|
return an error
|
|
[Rich Salz and Ismo Puustinen <ismo.puustinen@intel.com>]
|
|
|
|
*) Rewrite PSK to support ECDHE_PSK, DHE_PSK and RSA_PSK. Add ciphersuites
|
|
from RFC4279, RFC4785, RFC5487, RFC5489.
|
|
|
|
Thanks to Christian J. Dietrich and Giuseppe D'Angelo for the
|
|
original RSA_PSK patch.
|
|
[Steve Henson]
|
|
|
|
*) Dropped support for the SSL3_FLAGS_DELAY_CLIENT_FINISHED flag. This SSLeay
|
|
era flag was never set throughout the codebase (only read). Also removed
|
|
SSL3_FLAGS_POP_BUFFER which was only used if
|
|
SSL3_FLAGS_DELAY_CLIENT_FINISHED was also set.
|
|
[Matt Caswell]
|
|
|
|
*) Changed the default name options in the "ca", "crl", "req" and "x509"
|
|
to be "oneline" instead of "compat".
|
|
[Richard Levitte]
|
|
|
|
*) Remove SSL_OP_TLS_BLOCK_PADDING_BUG. This is SSLeay legacy, we're
|
|
not aware of clients that still exhibit this bug, and the workaround
|
|
hasn't been working properly for a while.
|
|
[Emilia Käsper]
|
|
|
|
*) The return type of BIO_number_read() and BIO_number_written() as well as
|
|
the corresponding num_read and num_write members in the BIO structure has
|
|
changed from unsigned long to uint64_t. On platforms where an unsigned
|
|
long is 32 bits (e.g. Windows) these counters could overflow if >4Gb is
|
|
transferred.
|
|
[Matt Caswell]
|
|
|
|
*) Given the pervasive nature of TLS extensions it is inadvisable to run
|
|
OpenSSL without support for them. It also means that maintaining
|
|
the OPENSSL_NO_TLSEXT option within the code is very invasive (and probably
|
|
not well tested). Therefore the OPENSSL_NO_TLSEXT option has been removed.
|
|
[Matt Caswell]
|
|
|
|
*) Removed support for the two export grade static DH ciphersuites
|
|
EXP-DH-RSA-DES-CBC-SHA and EXP-DH-DSS-DES-CBC-SHA. These two ciphersuites
|
|
were newly added (along with a number of other static DH ciphersuites) to
|
|
1.0.2. However the two export ones have *never* worked since they were
|
|
introduced. It seems strange in any case to be adding new export
|
|
ciphersuites, and given "logjam" it also does not seem correct to fix them.
|
|
[Matt Caswell]
|
|
|
|
*) Version negotiation has been rewritten. In particular SSLv23_method(),
|
|
SSLv23_client_method() and SSLv23_server_method() have been deprecated,
|
|
and turned into macros which simply call the new preferred function names
|
|
TLS_method(), TLS_client_method() and TLS_server_method(). All new code
|
|
should use the new names instead. Also as part of this change the ssl23.h
|
|
header file has been removed.
|
|
[Matt Caswell]
|
|
|
|
*) Support for Kerberos ciphersuites in TLS (RFC2712) has been removed. This
|
|
code and the associated standard is no longer considered fit-for-purpose.
|
|
[Matt Caswell]
|
|
|
|
*) RT2547 was closed. When generating a private key, try to make the
|
|
output file readable only by the owner. This behavior change might
|
|
be noticeable when interacting with other software.
|
|
|
|
*) Documented all exdata functions. Added CRYPTO_free_ex_index.
|
|
Added a test.
|
|
[Rich Salz]
|
|
|
|
*) Added HTTP GET support to the ocsp command.
|
|
[Rich Salz]
|
|
|
|
*) Changed default digest for the dgst and enc commands from MD5 to
|
|
sha256
|
|
[Rich Salz]
|
|
|
|
*) RAND_pseudo_bytes has been deprecated. Users should use RAND_bytes instead.
|
|
[Matt Caswell]
|
|
|
|
*) Added support for TLS extended master secret from
|
|
draft-ietf-tls-session-hash-03.txt. Thanks for Alfredo Pironti for an
|
|
initial patch which was a great help during development.
|
|
[Steve Henson]
|
|
|
|
*) All libssl internal structures have been removed from the public header
|
|
files, and the OPENSSL_NO_SSL_INTERN option has been removed (since it is
|
|
now redundant). Users should not attempt to access internal structures
|
|
directly. Instead they should use the provided API functions.
|
|
[Matt Caswell]
|
|
|
|
*) config has been changed so that by default OPENSSL_NO_DEPRECATED is used.
|
|
Access to deprecated functions can be re-enabled by running config with
|
|
"enable-deprecated". In addition applications wishing to use deprecated
|
|
functions must define OPENSSL_USE_DEPRECATED. Note that this new behaviour
|
|
will, by default, disable some transitive includes that previously existed
|
|
in the header files (e.g. ec.h will no longer, by default, include bn.h)
|
|
[Matt Caswell]
|
|
|
|
*) Added support for OCB mode. OpenSSL has been granted a patent license
|
|
compatible with the OpenSSL license for use of OCB. Details are available
|
|
at https://www.openssl.org/source/OCB-patent-grant-OpenSSL.pdf. Support
|
|
for OCB can be removed by calling config with no-ocb.
|
|
[Matt Caswell]
|
|
|
|
*) SSLv2 support has been removed. It still supports receiving a SSLv2
|
|
compatible client hello.
|
|
[Kurt Roeckx]
|
|
|
|
*) Increased the minimal RSA keysize from 256 to 512 bits [Rich Salz],
|
|
done while fixing the error code for the key-too-small case.
|
|
[Annie Yousar <a.yousar@informatik.hu-berlin.de>]
|
|
|
|
*) CA.sh has been removed; use CA.pl instead.
|
|
[Rich Salz]
|
|
|
|
*) Removed old DES API.
|
|
[Rich Salz]
|
|
|
|
*) Remove various unsupported platforms:

|
Sony NEWS4
|
|
BEOS and BEOS_R5
|
|
NeXT
|
|
SUNOS
|
|
MPE/iX

*) Experimental encrypt-then-mac support.
|
|
|
|
Experimental support for encrypt then mac from

|
draft-gutmann-tls-encrypt-then-mac-02.txt
|
|
|

To enable it set the appropriate extension number (0x42 for the test
|
|
server) using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x42
|
|
|
|
For non-compliant peers (i.e. just about everything) this should have no
|
|
effect.
|
|
|
|
WARNING: EXPERIMENTAL, SUBJECT TO CHANGE.
|
|
|
|
[Steve Henson]
|
|
|
|
*) Add EVP support for key wrapping algorithms, to avoid problems with
|
|
existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
|
|
the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap
|
|
algorithms and include tests cases.
|
|
[Steve Henson]
|
|
|
|
*) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for
|
|
enveloped data.
|
|
[Steve Henson]
|
|
|
|
*) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest,
|
|
MGF1 digest and OAEP label.
|
|
[Steve Henson]
|
|
|
|
*) Make openssl verify return errors.
|
|
[Chris Palmer <palmer@google.com> and Ben Laurie]
|
|
|
|
*) New function ASN1_TIME_diff to calculate the difference between two
|
|
ASN1_TIME structures or one structure and the current time.
|
|
[Steve Henson]
|
|
|
|
*) Update fips_test_suite to support multiple command line options. New
|
|
test to induce all self test errors in sequence and check expected
|
|
failures.
|
|
[Steve Henson]
|
|
|
|
*) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and
|
|
sign or verify all in one operation.
|
|
[Steve Henson]
|
|
|
|
*) Add fips_algvs: a multicall fips utility incorporating all the algorithm
|
|
test programs and fips_test_suite. Includes functionality to parse
|
|
the minimal script output of fipsalgest.pl directly.
|
|
[Steve Henson]
|
|
|
|
*) Add authorisation parameter to FIPS_module_mode_set().
|
|
[Steve Henson]
|
|
|
|
*) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves.
|
|
[Steve Henson]
|
|
|
|
*) Use separate DRBG fields for internal and external flags. New function
|
|
FIPS_drbg_health_check() to perform on demand health checking. Add
|
|
generation tests to fips_test_suite with reduced health check interval to
|
|
demonstrate periodic health checking. Add "nodh" option to
|
|
fips_test_suite to skip very slow DH test.
|
|
[Steve Henson]
|
|
|
|
*) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers
|
|
based on NID.
|
|
[Steve Henson]
|
|
|
|
*) More extensive health check for DRBG checking many more failure modes.
|
|
New function FIPS_selftest_drbg_all() to handle every possible DRBG
|
|
combination: call this in fips_test_suite.
|
|
[Steve Henson]
|
|
|
|
*) Add support for canonical generation of DSA parameter 'g'. See
|
|
FIPS 186-3 A.2.3.
|
|
|
|
*) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and
|
|
POST to handle HMAC cases.
|
|
[Steve Henson]
|
|
|
|
*) Add functions FIPS_module_version() and FIPS_module_version_text()
|
|
to return numerical and string versions of the FIPS module number.
|
|
[Steve Henson]
|
|
|
|
*) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and
|
|
FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented
|
|
outside the validated module in the FIPS capable OpenSSL.
|
|
[Steve Henson]
|
|
|
|
*) Minor change to DRBG entropy callback semantics. In some cases
|
|
there is no multiple of the block length between min_len and
|
|
max_len. Allow the callback to return more than max_len bytes
|
|
of entropy but discard any extra: it is the callback's responsibility
|
|
to ensure that the extra data discarded does not impact the
|
|
requested amount of entropy.
|
|
[Steve Henson]
|
|
|
|
*) Add PRNG security strength checks to RSA, DSA and ECDSA using
|
|
information in FIPS186-3, SP800-57 and SP800-131A.
|
|
[Steve Henson]
|
|
|
|
*) CCM support via EVP. Interface is very similar to GCM case except we
|
|
must supply all data in one chunk (i.e. no update, final) and the
|
|
message length must be supplied if AAD is used. Add algorithm test
|
|
support.
|
|
[Steve Henson]
|
|
|
|
*) Initial version of POST overhaul. Add POST callback to allow the status
|
|
of POST to be monitored and/or failures induced. Modify fips_test_suite
|
|
to use callback. Always run all selftests even if one fails.
|
|
[Steve Henson]
|
|
|
|
*) XTS support including algorithm test driver in the fips_gcmtest program.
|
|
Note: this does increase the maximum key length from 32 to 64 bytes but
|
|
there should be no binary compatibility issues as existing applications
|
|
will never use XTS mode.
|
|
[Steve Henson]
|
|
|
|
*) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies
|
|
to OpenSSL RAND code and replace with a tiny FIPS RAND API which also
|
|
performs algorithm blocking for unapproved PRNG types. Also do not
|
|
set PRNG type in FIPS_mode_set(): leave this to the application.
|
|
Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with
|
|
the standard OpenSSL PRNG: set additional data to a date time vector.
|
|
[Steve Henson]
|
|
|
|
*) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*.
|
|
This shouldn't present any incompatibility problems because applications
|
|
shouldn't be using these directly and any that are will need to rethink
|
|
anyway as the X9.31 PRNG is now deprecated by FIPS 140-2
|
|
[Steve Henson]
|
|
|
|
*) Extensive self tests and health checking required by SP800-90 DRBG.
|
|
Remove strength parameter from FIPS_drbg_instantiate and always
|
|
instantiate at maximum supported strength.
|
|
[Steve Henson]
|
|
|
|
*) Add ECDH code to fips module and fips_ecdhvs for primitives only testing.
|
|
[Steve Henson]
|
|
|
|
*) New algorithm test program fips_dhvs to handle DH primitives only testing.
|
|
[Steve Henson]
|
|
|
|
*) New function DH_compute_key_padded() to compute a DH key and pad with
|
|
leading zeroes if needed: this complies with SP800-56A et al.
|
|
[Steve Henson]
|
|
|
|
*) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by
|
|
anything, incomplete, subject to change and largely untested at present.
|
|
[Steve Henson]
|
|
|
|
*) Modify fipscanisteronly build option to only build the necessary object
|
|
files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile.
|
|
[Steve Henson]
|
|
|
|
*) Add experimental option FIPSSYMS to give all symbols in
|
|
fipscanister.o and FIPS or fips prefix. This will avoid
|
|
conflicts with future versions of OpenSSL. Add perl script
|
|
util/fipsas.pl to preprocess assembly language source files
|
|
and rename any affected symbols.
|
|
[Steve Henson]
|
|
|
|
*) Add selftest checks and algorithm block of non-fips algorithms in
|
|
FIPS mode. Remove DES2 from selftests.
|
|
[Steve Henson]
|
|
|
|
*) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just
|
|
return internal method without any ENGINE dependencies. Add new
|
|
tiny fips sign and verify functions.
|
|
[Steve Henson]
|
|
|
|
*) New build option no-ec2m to disable characteristic 2 code.
|
|
[Steve Henson]
|
|
|
|
*) New build option "fipscanisteronly". This only builds fipscanister.o
|
|
and (currently) associated fips utilities. Uses the file Makefile.fips
|
|
instead of Makefile.org as the prototype.
|
|
[Steve Henson]
|
|
|
|
*) Add some FIPS mode restrictions to GCM. Add internal IV generator.
|
|
Update fips_gcmtest to use IV generator.
|
|
[Steve Henson]
|
|
|
|
*) Initial, experimental EVP support for AES-GCM. AAD can be input by
|
|
setting output buffer to NULL. The *Final function must be
|
|
called although it will not retrieve any additional data. The tag
|
|
can be set or retrieved with a ctrl. The IV length is by default 12
|
|
bytes (96 bits) but can be set to an alternative value. If the IV
|
|
length exceeds the maximum IV length (currently 16 bytes) it cannot be
|
|
set before the key.
|
|
[Steve Henson]
|
|
|
|
*) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the
|
|
underlying do_cipher function handles all cipher semantics itself
|
|
including padding and finalisation. This is useful if (for example)
|
|
an ENGINE cipher handles block padding itself. The behaviour of
|
|
do_cipher is subtly changed if this flag is set: the return value
|
|
is the number of characters written to the output buffer (zero is
|
|
no longer an error code) or a negative error code. Also if the
|
|
input buffer is NULL and length 0 finalisation should be performed.
|
|
[Steve Henson]
|
|
|
|
*) If a candidate issuer certificate is already part of the constructed
|
|
path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case.
|
|
[Steve Henson]
|
|
|
|
*) Improve forward-security support: add functions
|
|
|
|
void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure))
|
|
void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure))
|
|
|
|
for use by SSL/TLS servers; the callback function will be called whenever a
|
|
new session is created, and gets to decide whether the session may be
|
|
cached to make it resumable (return 0) or not (return 1). (As by the
|
|
SSL/TLS protocol specifications, the session_id sent by the server will be
|
|
empty to indicate that the session is not resumable; also, the server will
|
|
not generate RFC 4507 (RFC 5077) session tickets.)
|
|
|
|
A simple reasonable callback implementation is to return is_forward_secure.
|
|
This parameter will be set to 1 or 0 depending on the ciphersuite selected
|
|
by the SSL/TLS server library, indicating whether it can provide forward
|
|
security.

*) New -verify_name option in command line utilities to set verification
|
|
parameters by name.
|
|
[Steve Henson]
|
|
|
|
*) Initial CMAC implementation. WARNING: EXPERIMENTAL, API MAY CHANGE.
|
|
Add CMAC pkey methods.
|
|
[Steve Henson]
|
|
|
|
*) Experimental renegotiation in s_server -www mode. If the client
|
|
browses /reneg connection is renegotiated. If /renegcert it is
|
|
renegotiated requesting a certificate.
|
|
[Steve Henson]
|
|
|
|
*) Add an "external" session cache for debugging purposes to s_server. This
|
|
should help trace issues which normally are only apparent in deployed
|
|
multi-process servers.
|
|
[Steve Henson]
|
|
|
|
*) Extensive audit of libcrypto with DEBUG_UNUSED. Fix many cases where
|
|
return value is ignored. NB. The functions RAND_add(), RAND_seed(),
|
|
BIO_set_cipher() and some obscure PEM functions were changed so they
|
|
can now return an error. The RAND changes required a change to the
|
|
RAND_METHOD structure.
|
|
[Steve Henson]
|
|
|
|
*) New macro __owur for "OpenSSL Warn Unused Result". This makes use of
|
|
a gcc attribute to warn if the result of a function is ignored. This
|
|
is enable if DEBUG_UNUSED is set. Add to several functions in evp.h
|
|
whose return value is often ignored.
|
|
[Steve Henson]
|
|
|
|
*) New -noct, -requestct, -requirect and -ctlogfile options for s_client.
|
|
These allow SCTs (signed certificate timestamps) to be requested and
|
|
validated when establishing a connection.

*) Prevent padding oracle in AES-NI CBC MAC check
|
|
|
|
A MITM attacker can use a padding oracle attack to decrypt traffic
|
|
when the connection uses an AES CBC cipher and the server support
|
|
AES-NI.
|
|
|
|
This issue was introduced as part of the fix for Lucky 13 padding
|
|
attack (CVE-2013-0169). The padding check was rewritten to be in
|
|
constant time by making sure that always the same bytes are read and
|
|
compared against either the MAC or padding bytes. But it no longer
|
|
checked that there was enough data to have both the MAC and padding
|
|
bytes.
|
|
|
|
This issue was reported by Juraj Somorovsky using TLS-Attacker.

[Kurt Roeckx]
|
|
|
|
*) Fix EVP_EncodeUpdate overflow
|
|
|
|
An overflow can occur in the EVP_EncodeUpdate() function which is used for
|
|
Base64 encoding of binary data. If an attacker is able to supply very large
|
|
amounts of input data then a length check can overflow resulting in a heap
|
|
corruption.
|
|
|
|
Internally to OpenSSL the EVP_EncodeUpdate() function is primarily used by
|
|
the PEM_write_bio* family of functions. These are mainly used within the
|
|
OpenSSL command line applications, so any application which processes data
|
|
from an untrusted source and outputs it as a PEM file should be considered
|
|
vulnerable to this issue. User applications that call these APIs directly
|
|
with large amounts of untrusted data may also be vulnerable.
|
|
|
|
This issue was reported by Guido Vranken.
|

(CVE-2016-2105)
|
|
[Matt Caswell]
|
|
|
|
*) Fix EVP_EncryptUpdate overflow
|
|
|
|
An overflow can occur in the EVP_EncryptUpdate() function. If an attacker
|
|
is able to supply very large amounts of input data after a previous call to
|
|
EVP_EncryptUpdate() with a partial block then a length check can overflow
|
|
resulting in a heap corruption. Following an analysis of all OpenSSL
|
|
internal usage of the EVP_EncryptUpdate() function all usage is one of two
|
|
forms. The first form is where the EVP_EncryptUpdate() call is known to be
|
|
the first called function after an EVP_EncryptInit(), and therefore that
|
|
specific call must be safe. The second form is where the length passed to
|
|
EVP_EncryptUpdate() can be seen from the code to be some small value and
|
|
therefore there is no possibility of an overflow. Since all instances are
|
|
one of these two forms, it is believed that there can be no overflows in
|
|
internal code due to this problem. It should be noted that
|
|
EVP_DecryptUpdate() can call EVP_EncryptUpdate() in certain code paths.
|
|
Also EVP_CipherUpdate() is a synonym for EVP_EncryptUpdate(). All instances
|
|
of these calls have also been analysed too and it is believed there are no
|
|
instances in internal usage where an overflow could occur.
|
|
|
|
This issue was reported by Guido Vranken.

|
|
*) Prevent ASN.1 BIO excessive memory allocation
|
|
|
|
When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio()
|
|
a short invalid encoding can cause allocation of large amounts of memory
|
|
potentially consuming excessive resources or exhausting memory.
|
|
|
|
Any application parsing untrusted data through d2i BIO functions is
|
|
affected. The memory based functions such as d2i_X509() are *not* affected.
|
|
Since the memory based functions are used by the TLS library, TLS
|
|
applications are not affected.

* Disable weak ciphers in SSLv3 and up in default builds of OpenSSL.

Builds that are not configured with "enable-weak-ssl-ciphers" will not
|
|
provide any "EXPORT" or "LOW" strength ciphers.
|
|
[Viktor Dukhovni]
|
|
|
|
* Disable SSLv2 default build, default negotiation and weak ciphers. SSLv2
|
|
is by default disabled at build-time. Builds that are not configured with
|
|
"enable-ssl2" will not support SSLv2. Even if "enable-ssl2" is used,
|
|
users who want to negotiate SSLv2 via the version-flexible SSLv23_method()
|
|
will need to explicitly call either of:
|
|
|

SSL_CTX_clear_options(ctx, SSL_OP_NO_SSLv2);
|
|
or
|
|
SSL_clear_options(ssl, SSL_OP_NO_SSLv2);
|
|
|
|
as appropriate. Even if either of those is used, or the application
|
|
explicitly uses the version-specific SSLv2_method() or its client and
|
|
server variants, SSLv2 ciphers vulnerable to exhaustive search key
|
|
recovery have been removed. Specifically, the SSLv2 40-bit EXPORT

*) Fix BN_hex2bn/BN_dec2bn NULL pointer deref/heap corruption
|
|
|
|
In the BN_hex2bn function the number of hex digits is calculated using an
|
|
int value |i|. Later |bn_expand| is called with a value of |i * 4|. For
|
|
large values of |i| this can result in |bn_expand| not allocating any
|
|
memory because |i * 4| is negative. This can leave the internal BIGNUM data
|
|
field as NULL leading to a subsequent NULL ptr deref. For very large values
|
|
of |i|, the calculation |i * 4| could be a positive value smaller than |i|.
|
|
In this case memory is allocated to the internal BIGNUM data field, but it
|
|
is insufficiently sized leading to heap corruption. A similar issue exists
|
|
in BN_dec2bn. This could have security consequences if BN_hex2bn/BN_dec2bn
|
|
is ever called by user applications with very large untrusted hex/dec data.
|
|
This is anticipated to be a rare occurrence.
|
|
|
|
All OpenSSL internal usage of these functions use data that is not expected
|
|
to be untrusted, e.g. config file data or application command line
|
|
arguments. If user developed applications generate config file data based
|
|
on untrusted data then it is possible that this could also lead to security
|
|
consequences. This is also anticipated to be rare.

|
|
*) Fix memory issues in BIO_*printf functions
|
|
|
|
The internal |fmtstr| function used in processing a "%s" format string in
|
|
the BIO_*printf functions could overflow while calculating the length of a
|
|
string and cause an OOB read when printing very long strings.
|
|
|
|
Additionally the internal |doapr_outch| function can attempt to write to an
|
|
OOB memory location (at an offset from the NULL pointer) in the event of a
|
|
memory allocation failure. In 1.0.2 and below this could be caused where
|
|
the size of a buffer to be allocated is greater than INT_MAX. E.g. this
|
|
could be in processing a very long "%s" format string. Memory leaks can
|
|
also occur.
|
|
|
|
The first issue may mask the second issue dependent on compiler behaviour.
|
|
These problems could enable attacks where large amounts of untrusted data
|
|
is passed to the BIO_*printf functions. If applications use these functions
|
|
in this way then they could be vulnerable. OpenSSL itself uses these
|
|
functions when printing out human-readable dumps of ASN.1 data. Therefore
|
|
applications that print this data could be vulnerable if the data is from
|
|
untrusted sources. OpenSSL command line applications could also be
|
|
vulnerable where they print out ASN.1 data, or if untrusted data is passed
|
|
as command line arguments.
|
|
|
|
Libssl is not considered directly vulnerable. Additionally certificates etc
|
|
received via remote connections via libssl are also unlikely to be able to
|
|
trigger these issues because of message size limits enforced within libssl.

Changes between 1.0.2e and 1.0.2f [28 Jan 2016]
|
|
*) DH small subgroups
|
|
|
|
Historically OpenSSL only ever generated DH parameters based on "safe"
|
|
primes. More recently (in version 1.0.2) support was provided for
|
|
generating X9.42 style parameter files such as those required for RFC 5114
|
|
support. The primes used in such files may not be "safe". Where an
|
|
application is using DH configured with parameters based on primes that are
|
|
not "safe" then an attacker could use this fact to find a peer's private
|
|
DH exponent. This attack requires that the attacker complete multiple
|
|
handshakes in which the peer uses the same private DH exponent. For example
|
|
this could be used to discover a TLS server's private DH exponent if it's
|
|
reusing the private DH exponent or it's using a static DH ciphersuite.
|
|
|
|
OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in
|
|
TLS. It is not on by default. If the option is not set then the server
|
|
reuses the same private DH exponent for the life of the server process and
|
|
would be vulnerable to this attack. It is believed that many popular
|
|
applications do set this option and would therefore not be at risk.
|
|
|
|
The fix for this issue adds an additional check where a "q" parameter is
|
|
available (as is the case in X9.42 based parameters). This detects the
|
|
only known attack, and is the only possible defense for static DH
|
|
ciphersuites. This could have some performance impact.
|
|
|
|
Additionally the SSL_OP_SINGLE_DH_USE option has been switched on by
|
|
default and cannot be disabled. This could have some performance impact.

*) BN_mod_exp may produce incorrect results on x86_64
|
|
|
|
There is a carry propagating bug in the x86_64 Montgomery squaring
|
|
procedure. No EC algorithms are affected. Analysis suggests that attacks
|
|
against RSA and DSA as a result of this defect would be very difficult to
|
|
perform and are not believed likely. Attacks against DH are considered just
|
|
feasible (although very difficult) because most of the work necessary to
|
|
deduce information about a private key may be performed offline. The amount
|
|
of resources required for such an attack would be very significant and
|
|
likely only accessible to a limited number of attackers. An attacker would
|
|
additionally need online access to an unpatched system using the target
|
|
private key in a scenario with persistent DH parameters and a private
|
|
key that is shared between multiple clients. For example this can occur by
|

default in OpenSSL DHE based SSL/TLS ciphersuites.

OpenSSL 1.0.2 introduced the "multiblock" performance improvement. This

feature only applies on 64 bit x86 architecture platforms that support AES
|
|
NI instructions. A defect in the implementation of "multiblock" can cause
|
|
OpenSSL's internal write buffer to become incorrectly set to NULL when
|
|
using non-blocking IO. Typically, when the user application is using a
|
|
socket BIO for writing, this will only result in a failed connection.
|
|
However if some other BIO is used then it is likely that a segmentation
|
|
fault will be triggered, thus enabling a potential DoS attack.

*) Segmentation fault in DTLSv1_listen fix
|

The DTLSv1_listen function is intended to be stateless and processes the

initial ClientHello from many peers. It is common for user code to loop
|
|
over the call to DTLSv1_listen until a valid ClientHello is received with
|
|
an associated cookie. A defect in the implementation of DTLSv1_listen means
|
|
that state is preserved in the SSL object from one invocation to the next
|
|
that can lead to a segmentation fault. Errors processing the initial
|
|
ClientHello can trigger this scenario. An example of such an error could be
|
|
that a DTLS1.0 only client is attempting to connect to a DTLS1.2 only
|
|
server.

|
|
*) Handshake with unseeded PRNG fix
|
|
|
|
Under certain conditions an OpenSSL 1.0.2 client can complete a handshake
|
|
with an unseeded PRNG. The conditions are:
|
|
- The client is on a platform where the PRNG has not been seeded
|
|
automatically, and the user has not seeded manually
|
|
- A protocol specific client method version has been used (i.e. not
|
|
SSL_client_methodv23)
|
|
- A ciphersuite is used that does not require additional random data from
|
|
the PRNG beyond the initial ClientHello client random (e.g. PSK-RC4-SHA).
|
|
|
|
If the handshake succeeds then the client random that has been used will
|
|
have been generated from a PRNG with insufficient entropy and therefore the
|
|
output may be predictable.
|
|
|
|
For example using the following command with an unseeded openssl will
|
|
succeed on an unpatched platform:
|
|
|
|
openssl s_client -psk 1a2b3c4d -tls1_2 -cipher PSK-RC4-SHA

could cause a use after free condition. This, in turn, could cause a double
|
|
free in several private key parsing functions (such as d2i_PrivateKey

|
This covers AES, SHA256/512 and GHASH. "Initial" means that most
|
|
common cases are optimized and there still is room for further
|
|
improvements. Vector Permutation AES for Altivec is also added.
|
|
[Andy Polyakov]
|
|
|
|
*) Add support for little-endian ppc64 Linux target.
|
|
[Marcelo Cerri (IBM)]
|
|
|
|
*) Initial support for AMRv8 ISA crypto extensions. This covers AES,
|
|
SHA1, SHA256 and GHASH. "Initial" means that most common cases
|
|
are optimized and there still is room for further improvements.
|
|
Both 32- and 64-bit modes are supported.
|
|
[Andy Polyakov, Ard Biesheuvel (Linaro)]
|
|
|
|
*) Improved ARMv7 NEON support.
|
|
[Andy Polyakov]
|
|
|
|
*) Support for SPARC Architecture 2011 crypto extensions, first
|
|
implemented in SPARC T4. This covers AES, DES, Camellia, SHA1,
|
|
SHA256/512, MD5, GHASH and modular exponentiation.
|
|
[Andy Polyakov, David Miller]
|
|
|
|
*) Accelerated modular exponentiation for Intel processors, a.k.a.
|
|
RSAZ.
|
|
[Shay Gueron & Vlad Krasnov (Intel Corp)]
|
|
|
|
*) Support for new and upcoming Intel processors, including AVX2,
|
|
BMI and SHA ISA extensions. This includes additional "stitched"
|
|
implementations, AESNI-SHA256 and GCM, and multi-buffer support
|
|
for TLS encrypt.
|
|
|
|
This work was sponsored by Intel Corp.
|
|
[Andy Polyakov]
|
|
|
|
*) Support for DTLS 1.2. This adds two sets of DTLS methods: DTLS_*_method()
|
|
supports both DTLS 1.2 and 1.0 and should use whatever version the peer
|
|
supports and DTLSv1_2_*_method() which supports DTLS 1.2 only.
|
|
[Steve Henson]
|
|
|
|
*) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file():
|
|
this fixes a limitation in previous versions of OpenSSL.
|
|
[Steve Henson]
|
|
|
|
*) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest,
|
|
MGF1 digest and OAEP label.
|
|
[Steve Henson]
|
|
|
|
*) Add EVP support for key wrapping algorithms, to avoid problems with
|
|
existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
|
|
the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap
|
|
algorithms and include tests cases.
|
|
[Steve Henson]
|
|
|
|
*) Add functions to allocate and set the fields of an ECDSA_METHOD
|
|
structure.
|
|
[Douglas E. Engert, Steve Henson]
|
|
|
|
*) New functions OPENSSL_gmtime_diff and ASN1_TIME_diff to find the
|
|
difference in days and seconds between two tm or ASN1_TIME structures.
|
|
[Steve Henson]
|
|
|
|
*) Add -rev test option to s_server to just reverse order of characters
|
|
received by client and send back to server. Also prints an abbreviated
|
|
summary of the connection parameters.
|
|
[Steve Henson]
|
|
|
|
*) New option -brief for s_client and s_server to print out a brief summary
|
|
of connection parameters.
|
|
[Steve Henson]
|
|
|
|
*) Add callbacks for arbitrary TLS extensions.
|
|
[Trevor Perrin <trevp@trevp.net> and Ben Laurie]
|
|
|
|
*) New option -crl_download in several openssl utilities to download CRLs
|
|
from CRLDP extension in certificates.
|
|
[Steve Henson]
|
|
|
|
*) New options -CRL and -CRLform for s_client and s_server for CRLs.
|
|
[Steve Henson]
|
|
|
|
*) New function X509_CRL_diff to generate a delta CRL from the difference
|
|
of two full CRLs. Add support to "crl" utility.
|
|
[Steve Henson]
|
|
|
|
*) New functions to set lookup_crls function and to retrieve
|
|
X509_STORE from X509_STORE_CTX.
|
|
[Steve Henson]
|
|
|
|
*) Print out deprecated issuer and subject unique ID fields in
|
|
certificates.
|
|
[Steve Henson]
|
|
|
|
*) Extend OCSP I/O functions so they can be used for simple general purpose
|
|
HTTP as well as OCSP. New wrapper function which can be used to download
|
|
CRLs using the OCSP API.
|
|
[Steve Henson]
|
|
|
|
*) Delegate command line handling in s_client/s_server to SSL_CONF APIs.
|
|
[Steve Henson]
|
|
|
|
*) SSL_CONF* functions. These provide a common framework for application
|
|
configuration using configuration files or command lines.
|
|
[Steve Henson]
|
|
|
|
*) SSL/TLS tracing code. This parses out SSL/TLS records using the
|
|
message callback and prints the results. Needs compile time option
|
|
"enable-ssl-trace". New options to s_client and s_server to enable
|
|
tracing.
|
|
[Steve Henson]
|
|
|
|
*) New ctrl and macro to retrieve supported points extensions.
|
|
Print out extension in s_server and s_client.
|
|
[Steve Henson]
|
|
|
|
*) New functions to retrieve certificate signature and signature
|
|
OID NID.
|
|
[Steve Henson]
|
|
|
|
*) Add functions to retrieve and manipulate the raw cipherlist sent by a
|
|
client to OpenSSL.
|
|
[Steve Henson]
|
|
|
|
*) New Suite B modes for TLS code. These use and enforce the requirements
|
|
of RFC6460: restrict ciphersuites, only permit Suite B algorithms and
|
|
only use Suite B curves. The Suite B modes can be set by using the
|
|
strings "SUITEB128", "SUITEB192" or "SUITEB128ONLY" for the cipherstring.
|
|
[Steve Henson]
|
|
|
|
*) New chain verification flags for Suite B levels of security. Check
|
|
algorithms are acceptable when flags are set in X509_verify_cert.
|
|
[Steve Henson]
|
|
|
|
*) Make tls1_check_chain return a set of flags indicating checks passed
|
|
by a certificate chain. Add additional tests to handle client
|
|
certificates: checks for matching certificate type and issuer name
|
|
comparison.
|
|
[Steve Henson]
|
|
|
|
*) If an attempt is made to use a signature algorithm not in the peer
|
|
preference list abort the handshake. If client has no suitable
|
|
signature algorithms in response to a certificate request do not
|
|
use the certificate.
|
|
[Steve Henson]
|
|
|
|
*) If server EC tmp key is not in client preference list abort handshake.
|
|
[Steve Henson]
|
|
|
|
*) Add support for certificate stores in CERT structure. This makes it
|
|
possible to have different stores per SSL structure or one store in
|
|
the parent SSL_CTX. Include distinct stores for certificate chain
|
|
verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN
|
|
to build and store a certificate chain in CERT structure: returning
|
|
an error if the chain cannot be built: this will allow applications
|
|
to test if a chain is correctly configured.
|
|
|
|
Note: if the CERT based stores are not set then the parent SSL_CTX
|
|
store is used to retain compatibility with existing behaviour.
|
|
|
|
[Steve Henson]
|
|
|
|
*) New function ssl_set_client_disabled to set a ciphersuite disabled
|
|
mask based on the current session, check mask when sending client
|
|
hello and checking the requested ciphersuite.
|
|
[Steve Henson]
|
|
|
|
*) New ctrls to retrieve and set certificate types in a certificate
|
|
request message. Print out received values in s_client. If certificate
|
|
types is not set with custom values set sensible values based on
|
|
supported signature algorithms.
|
|
[Steve Henson]
|
|
|
|
*) Support for distinct client and server supported signature algorithms.
|
|
[Steve Henson]
|
|
|
|
*) Add certificate callback. If set this is called whenever a certificate
|
|
is required by client or server. An application can decide which
|
|
certificate chain to present based on arbitrary criteria: for example
|
|
supported signature algorithms. Add very simple example to s_server.
|
|
This fixes many of the problems and restrictions of the existing client
|
|
certificate callback: for example you can now clear an existing
|
|
certificate and specify the whole chain.
|
|
[Steve Henson]
|
|
|
|
*) Add new "valid_flags" field to CERT_PKEY structure which determines what
|
|
the certificate can be used for (if anything). Set valid_flags field
|
|
in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
|
|
to have similar checks in it.
|
|
|
|
Add new "cert_flags" field to CERT structure and include a "strict mode".
|
|
This enforces some TLS certificate requirements (such as only permitting
|
|
certificate signature algorithms contained in the supported algorithms
|
|
extension) which some implementations ignore: this option should be used
|
|
with caution as it could cause interoperability issues.
|
|
[Steve Henson]
|
|
|
|
*) Update and tidy signature algorithm extension processing. Work out
|
|
shared signature algorithms based on preferences and peer algorithms
|
|
and print them out in s_client and s_server. Abort handshake if no
|
|
shared signature algorithms.
|
|
[Steve Henson]
|
|
|
|
*) Add new functions to allow customised supported signature algorithms
|
|
for SSL and SSL_CTX structures. Add options to s_client and s_server
|
|
to support them.
|
|
[Steve Henson]
|
|
|
|
*) New function SSL_certs_clear() to delete all references to certificates
|
|
from an SSL structure. Before this once a certificate had been added
|
|
it couldn't be removed.
|
|
[Steve Henson]
|
|
|
|
*) Integrate hostname, email address and IP address checking with certificate
|
|
verification. New verify options supporting checking in openssl utility.
|
|
[Steve Henson]
|
|
|
|
*) Fixes and wildcard matching support to hostname and email checking
|
|
functions. Add manual page.
|
|
[Florian Weimer (Red Hat Product Security Team)]
|
|
|
|
*) New functions to check a hostname email or IP address against a
|
|
certificate. Add options x509 utility to print results of checks against
|
|
a certificate.
|
|
[Steve Henson]
|
|
|
|
*) Fix OCSP checking.
|
|
[Rob Stradling <rob.stradling@comodo.com> and Ben Laurie]
|
|
|
|
*) Initial experimental support for explicitly trusted non-root CAs.
|
|
OpenSSL still tries to build a complete chain to a root but if an
|
|
intermediate CA has a trust setting included that is used. The first
|
|
setting is used: whether to trust (e.g., -addtrust option to the x509
|
|
utility) or reject.
|
|
[Steve Henson]
|
|
|
|
*) Add -trusted_first option which attempts to find certificates in the
|
|
trusted store even if an untrusted chain is also supplied.
|
|
[Steve Henson]
|
|
|
|
*) MIPS assembly pack updates: support for MIPS32r2 and SmartMIPS ASE,
|
|
platform support for Linux and Android.
|
|
[Andy Polyakov]
|
|
|
|
*) Support for linux-x32, ILP32 environment in x86_64 framework.
|
|
[Andy Polyakov]
|
|
|
|
*) Experimental multi-implementation support for FIPS capable OpenSSL.
|
|
When in FIPS mode the approved implementations are used as normal,
|
|
when not in FIPS mode the internal unapproved versions are used instead.
|
|
This means that the FIPS capable OpenSSL isn't forced to use the
|
|
(often lower performance) FIPS implementations outside FIPS mode.
|
|
[Steve Henson]
|
|
|
|
*) Transparently support X9.42 DH parameters when calling
|
|
PEM_read_bio_DHparameters. This means existing applications can handle
|
|
the new parameter format automatically.
|
|
[Steve Henson]
|
|
|
|
*) Initial experimental support for X9.42 DH parameter format: mainly
|
|
to support use of 'q' parameter for RFC5114 parameters.
|
|
[Steve Henson]
|
|
|
|
*) Add DH parameters from RFC5114 including test data to dhtest.
|
|
[Steve Henson]
|
|
|
|
*) Support for automatic EC temporary key parameter selection. If enabled
|
|
the most preferred EC parameters are automatically used instead of
|
|
hardcoded fixed parameters. Now a server just has to call:
|
|
SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically
|
|
support ECDH and use the most appropriate parameters.
|
|
[Steve Henson]
|
|
|
|
*) Enhance and tidy EC curve and point format TLS extension code. Use
|
|
static structures instead of allocation if default values are used.
|
|
New ctrls to set curves we wish to support and to retrieve shared curves.
|
|
Print out shared curves in s_server. New options to s_server and s_client
|
|
to set list of supported curves.
|
|
[Steve Henson]
|
|
|
|
*) New ctrls to retrieve supported signature algorithms and
|
|
supported curve values as an array of NIDs. Extend openssl utility
|
|
to print out received values.
|
|
[Steve Henson]
|
|
|
|
*) Add new APIs EC_curve_nist2nid and EC_curve_nid2nist which convert
|
|
between NIDs and the more common NIST names such as "P-256". Enhance
|
|
ecparam utility and ECC method to recognise the NIST names for curves.
|
|
[Steve Henson]
|
|
|
|
*) Enhance SSL/TLS certificate chain handling to support different
|
|
chains for each certificate instead of one chain in the parent SSL_CTX.
|
|
[Steve Henson]
|
|
|
|
*) Support for fixed DH ciphersuite client authentication: where both
|
|
server and client use DH certificates with common parameters.
|
|
[Steve Henson]
|
|
|
|
*) Support for fixed DH ciphersuites: those requiring DH server
|
|
certificates.
|
|
[Steve Henson]
|
|
|
|
*) New function i2d_re_X509_tbs for re-encoding the TBS portion of
|
|
the certificate.
|
|
Note: Related 1.0.2-beta specific macros X509_get_cert_info,
|
|
X509_CINF_set_modified, X509_CINF_get_issuer, X509_CINF_get_extensions and
|
|
X509_CINF_get_signature were reverted post internal team review.

Changes between 1.0.1j and 1.0.1k [8 Jan 2015]
|
|
|
|
*) Fix DTLS segmentation fault in dtls1_get_record. A carefully crafted DTLS
|
|
message can cause a segmentation fault in OpenSSL due to a NULL pointer
|
|
dereference. This could lead to a Denial Of Service attack. Thanks to
|
|
Markus Stenberg of Cisco Systems, Inc. for reporting this issue.
|
|
(CVE-2014-3571)
|
|
[Steve Henson]
|
|
|
|
*) Fix DTLS memory leak in dtls1_buffer_record. A memory leak can occur in the
|
|
dtls1_buffer_record function under certain conditions. In particular this
|
|
could occur if an attacker sent repeated DTLS records with the same
|
|
sequence number but for the next epoch. The memory leak could be exploited
|
|
by an attacker in a Denial of Service attack through memory exhaustion.
|
|
Thanks to Chris Mueller for reporting this issue.
|
|
(CVE-2015-0206)
|
|
[Matt Caswell]
|
|
|
|
*) Fix issue where no-ssl3 configuration sets method to NULL. When openssl is
|
|
built with the no-ssl3 option and a SSL v3 ClientHello is received the ssl
|
|
method would be set to NULL which could later result in a NULL pointer
|
|
dereference. Thanks to Frank Schmirler for reporting this issue.
|
|
(CVE-2014-3569)

[Kurt Roeckx]
|
|
|
|
*) Abort handshake if server key exchange message is omitted for ephemeral
|
|
ECDH ciphersuites.

|
|
|
Thanks to Karthikeyan Bhargavan of the PROSECCO team at INRIA for
|
|
reporting this issue.
|
|
(CVE-2014-3572)
|
|
[Steve Henson]
|
|
|
|
*) Remove non-export ephemeral RSA code on client and server. This code
|
|
violated the TLS standard by allowing the use of temporary RSA keys in
|
|
non-export ciphersuites and could be used by a server to effectively
|
|
downgrade the RSA key length used to a value smaller than the server
|
|
certificate. Thanks for Karthikeyan Bhargavan of the PROSECCO team at
|
|
INRIA or reporting this issue.
|
|
(CVE-2015-0204)
|
|
[Steve Henson]
|
|
|
|
*) Fixed issue where DH client certificates are accepted without verification.
|
|
An OpenSSL server will accept a DH certificate for client authentication
|
|
without the certificate verify message. This effectively allows a client to
|
|
authenticate without the use of a private key. This only affects servers
|
|
which trust a client certificate authority which issues certificates
|
|
containing DH keys: these are extremely rare and hardly ever encountered.
|
|
Thanks for Karthikeyan Bhargavan of the PROSECCO team at INRIA or reporting
|
|
this issue.
|

(CVE-2015-0205)
|
|
[Steve Henson]
|
|
|
|
*) Ensure that the session ID context of an SSL is updated when its
|
|
SSL_CTX is updated via SSL_set_SSL_CTX.
|
|
|
|
The session ID context is typically set from the parent SSL_CTX,
|
|
and can vary with the CTX.
|
|
[Adam Langley]
|
|
|
|
*) Fix various certificate fingerprint issues.
|
|
|
|
By using non-DER or invalid encodings outside the signed portion of a
|
|
certificate the fingerprint can be changed without breaking the signature.
|
|
Although no details of the signed portion of the certificate can be changed
|
|
this can cause problems with some applications: e.g. those using the
|
|
certificate fingerprint for blacklists.
|
|
|
|
1. Reject signatures with non zero unused bits.
|
|
|
|
If the BIT STRING containing the signature has non zero unused bits reject
|
|
the signature. All current signature algorithms require zero unused bits.
|
|
|
|
2. Check certificate algorithm consistency.
|
|
|
|
Check the AlgorithmIdentifier inside TBS matches the one in the
|
|
certificate signature. NB: this will result in signature failure
|
|
errors for some broken certificates.
|
|
|
|
Thanks to Konrad Kraszewski from Google for reporting this issue.
|
|
|
|
3. Check DSA/ECDSA signatures use DER.
|
|
|
|
Re-encode DSA/ECDSA signatures and compare with the original received
|
|
signature. Return an error if there is a mismatch.
|
|
|
|
This will reject various cases including garbage after signature
|
|
(thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS
|
|
program for discovering this case) and use of BER or invalid ASN.1 INTEGERs
|
|
(negative or with leading zeroes).
|
|
|

Further analysis was conducted and fixes were developed by Stephen Henson
|
|
of the OpenSSL core team.

(CVE-2014-8275)
|
|
[Steve Henson]
|
|
|
|
*) Correct Bignum squaring. Bignum squaring (BN_sqr) may produce incorrect
|
|
results on some platforms, including x86_64. This bug occurs at random
|
|
with a very low probability, and is not known to be exploitable in any
|
|
way, though its exact impact is difficult to determine. Thanks to Pieter
|
|
Wuille (Blockstream) who reported this issue and also suggested an initial
|
|
fix. Further analysis was conducted by the OpenSSL development team and
|
|
Adam Langley of Google. The final fix was developed by Andy Polyakov of
|
|
the OpenSSL core team.

[Andy Polyakov]
|
|
|
|
*) Do not resume sessions on the server if the negotiated protocol
|
|
version does not match the session's version. Resuming with a different
|
|
version, while not strictly forbidden by the RFC, is of questionable
|
|
sanity and breaks all known clients.
|
|
[David Benjamin, Emilia Käsper]
|
|
|
|
*) Tighten handling of the ChangeCipherSpec (CCS) message: reject
|
|
early CCS messages during renegotiation. (Note that because
|
|
renegotiation is encrypted, this early CCS was not exploitable.)
|
|
[Emilia Käsper]
|
|
|
|
*) Tighten client-side session ticket handling during renegotiation:
|
|
ensure that the client only accepts a session ticket if the server sends
|
|
the extension anew in the ServerHello. Previously, a TLS client would
|
|
reuse the old extension state and thus accept a session ticket if one was
|
|
announced in the initial ServerHello.
|
|
|
|
Similarly, ensure that the client requires a session ticket if one
|
|
was advertised in the ServerHello. Previously, a TLS client would
|
|
ignore a missing NewSessionTicket message.

|
|
|
|
*) SRTP Memory Leak.
|
|
|
|
A flaw in the DTLS SRTP extension parsing code allows an attacker, who
|
|
sends a carefully crafted handshake message, to cause OpenSSL to fail
|
|
to free up to 64k of memory causing a memory leak. This could be
|
|
exploited in a Denial Of Service attack. This issue affects OpenSSL
|
|
1.0.1 server implementations for both SSL/TLS and DTLS regardless of
|
|
whether SRTP is used or configured. Implementations of OpenSSL that
|
|
have been compiled with OPENSSL_NO_SRTP defined are not affected.
|
|
|
|
The fix was developed by the OpenSSL team.
|
|
(CVE-2014-3513)
|
|
[OpenSSL team]
|
|
|
|
*) Session Ticket Memory Leak.
|
|
|
|
When an OpenSSL SSL/TLS/DTLS server receives a session ticket the
|
|
integrity of that ticket is first verified. In the event of a session
|
|
ticket integrity check failing, OpenSSL will fail to free memory
|
|
causing a memory leak. By sending a large number of invalid session
|
|
tickets an attacker could exploit this issue in a Denial Of Service
|
|
attack.

(CVE-2014-3567)
|
|
[Steve Henson]
|
|
|
|
*) Build option no-ssl3 is incomplete.
|
|
|
|
When OpenSSL is configured with "no-ssl3" as a build option, servers
|
|
could accept and complete a SSL 3.0 handshake, and clients could be
|
|
configured to send them.

[Adam Langley, Bodo Moeller]
|
|
|
|
*) Add additional DigestInfo checks.
|
|
|
|
Re-encode DigestInto in DER and check against the original when
|

verifying RSA signature: this will reject any improperly encoded
|
|
DigestInfo structures.
|
|
|
|
Note: this is a precautionary measure and no attacks are currently known.

(CVE-2014-3512)
|
|
[Steve Henson]
|
|
|
|
*) A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate
|
|
TLS 1.0 instead of higher protocol versions when the ClientHello message
|
|
is badly fragmented. This allows a man-in-the-middle attacker to force a
|
|
downgrade to TLS 1.0 even if both the server and the client support a
|
|
higher protocol version, by modifying the client's TLS records.
|
|
|
|
Thanks to David Benjamin and Adam Langley (Google) for discovering and

|
|
(CVE-2014-3511)
|
|
[David Benjamin]
|
|
|
|
*) OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject
|
|
to a denial of service attack. A malicious server can crash the client
|
|
with a null pointer dereference (read) by specifying an anonymous (EC)DH
|
|
ciphersuite and sending carefully crafted handshake messages.

(CVE-2014-3510)
|
|
[Emilia Käsper]
|
|
|
|
*) By sending carefully crafted DTLS packets an attacker could cause openssl
|
|
to leak memory. This can be exploited through a Denial of Service attack.
|
|
Thanks to Adam Langley for discovering and researching this issue.
|
|
(CVE-2014-3507)
|
|
[Adam Langley]
|
|
|
|
*) An attacker can force openssl to consume large amounts of memory whilst
|
|
processing DTLS handshake messages. This can be exploited through a
|
|
Denial of Service attack.
|
|
Thanks to Adam Langley for discovering and researching this issue.
|
|
(CVE-2014-3506)
|
|
[Adam Langley]
|
|
|
|
*) An attacker can force an error condition which causes openssl to crash
|
|
whilst processing DTLS packets due to memory being freed twice. This
|
|
can be exploited through a Denial of Service attack.
|
|
Thanks to Adam Langley and Wan-Teh Chang for discovering and researching
|
|
this issue.
|
|
(CVE-2014-3505)
|
|
[Adam Langley]
|
|
|
|
*) If a multithreaded client connects to a malicious server using a resumed
|
|
session and the server sends an ec point format extension it could write
|
|
up to 255 bytes to freed memory.
|
|
|
|

issue.
|
|
(CVE-2014-3509)
|
|
[Gabor Tyukasz]
|
|
|
|
*) A malicious server can crash an OpenSSL client with a null pointer
|
|
dereference (read) by specifying an SRP ciphersuite even though it was not
|
|
properly negotiated with the client. This can be exploited through a
|
|
Denial of Service attack.

discovering and researching this issue.
|
|
(CVE-2014-5139)
|
|
[Steve Henson]
|
|
|
|
*) A flaw in OBJ_obj2txt may cause pretty printing functions such as
|
|
X509_name_oneline, X509_name_print_ex et al. to leak some information
|
|
from the stack. Applications may be affected if they echo pretty printing
|
|
output to the attacker.

(CVE-2014-3508)
|
|
[Emilia Käsper, and Steve Henson]
|
|
|
|
*) Fix ec_GFp_simple_points_make_affine (thus, EC_POINTs_mul etc.)
|
|
for corner cases. (Certain input points at infinity could lead to
|
|
bogus results, with non-infinity inputs mapped to infinity too.)

[Bodo Moeller]
|
|
|
|
Changes between 1.0.1g and 1.0.1h [5 Jun 2014]
|
|
|
|
*) Fix for SSL/TLS MITM flaw. An attacker using a carefully crafted
|
|
handshake can force the use of weak keying material in OpenSSL
|
|
SSL/TLS clients and servers.

|
researching this issue. (CVE-2014-0224)
|
|
[KIKUCHI Masashi, Steve Henson]
|
|
|
|
*) Fix DTLS recursion flaw. By sending an invalid DTLS handshake to an
|
|
OpenSSL DTLS client the code can be made to recurse eventually crashing
|
|
in a DoS attack.
|
|
|
|
Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue.
|
|
(CVE-2014-0221)
|
|
[Imre Rad, Steve Henson]
|
|
|
|
*) Fix DTLS invalid fragment vulnerability. A buffer overrun attack can
|
|
be triggered by sending invalid DTLS fragments to an OpenSSL DTLS
|
|
client or server. This is potentially exploitable to run arbitrary
|
|
code on a vulnerable client or server.

Changes between 1.0.1f and 1.0.1g [7 Apr 2014]
|
|
|
|
*) A missing bounds check in the handling of the TLS heartbeat extension
|
|
can be used to reveal up to 64k of memory to a connected client or

flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076)
|
|
[Yuval Yarom and Naomi Benger]
|
|
|
|
*) TLS pad extension: draft-agl-tls-padding-03
|
|
|
|
Workaround for the "TLS hang bug" (see FAQ and PR#2771): if the
|
|
TLS client Hello record length value would otherwise be > 255 and
|
|
less that 512 pad with a dummy extension containing zeroes so it
|
|
is at least 512 bytes long.

[Adam Langley, Steve Henson]
|
|
|
|
Changes between 1.0.1e and 1.0.1f [6 Jan 2014]
|
|
|
|
*) Fix for TLS record tampering bug. A carefully crafted invalid
|
|
handshake could crash OpenSSL with a NULL pointer exception.
|
|
Thanks to Anton Johansson for reporting this issues.
|
|
(CVE-2013-4353)
|
|
|
|
*) Keep original DTLS digest and encryption contexts in retransmission
|
|
structures so we can use the previous session parameters if they need
|
|
to be resent. (CVE-2013-6450)
|
|
[Steve Henson]
|
|
|
|
*) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which
|
|
avoids preferring ECDHE-ECDSA ciphers when the client appears to be
|
|
Safari on OS X. Safari on OS X 10.8..10.8.3 advertises support for
|
|
several ECDHE-ECDSA ciphers, but fails to negotiate them. The bug
|
|
is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing
|
|
10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer.

[Andy Polyakov, Steve Henson]
|
|
|
|
Changes between 1.0.1c and 1.0.1d [5 Feb 2013]
|
|
|
|
*) Make the decoding of SSLv3, TLS and DTLS CBC records constant time.
|
|

This fixes a DoS attack. (CVE-2013-0166)
|
|
[Steve Henson]
|
|
|
|
*) Make openssl verify return errors.
|
|
[Chris Palmer <palmer@google.com> and Ben Laurie]
|
|
|
|
*) Call OCSP Stapling callback after ciphersuite has been chosen, so
|
|
the right response is stapled. Also change SSL_get_certificate()
|
|
so it returns the certificate actually sent.

|
|
|
Changes between 1.0.1b and 1.0.1c [10 May 2012]

[Steve Henson]
|
|
|
|
*) Initialise tkeylen properly when encrypting CMS messages.
|
|
Thanks to Solar Designer of Openwall for reporting this issue.
|

[Steve Henson]
|
|
|
|
*) In FIPS mode don't try to use composite ciphers as they are not

approved.
|
|
[Steve Henson]
|
|
|
|
Changes between 1.0.1a and 1.0.1b [26 Apr 2012]
|
|
|
|
*) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and
|
|
1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately
|
|
mean any application compiled against OpenSSL 1.0.0 headers setting
|
|
SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disabling
|
|
TLS 1.1 also. Fix this by changing the value of SSL_OP_NO_TLSv1_1 to
|
|
0x10000000L Any application which was previously compiled against
|
|
OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1
|
|
will need to be recompiled as a result. Letting be results in
|
|
inability to disable specifically TLS 1.1 and in client context,
|
|
in unlike event, limit maximum offered version to TLS 1.0 [see below].
|
|
[Steve Henson]
|
|
|
|
*) In order to ensure interoperability SSL_OP_NO_protocolX does not
|
|
disable just protocol X, but all protocols above X *if* there are
|
|
protocols *below* X still enabled. In more practical terms it means
|
|
that if application wants to disable TLS1.0 in favor of TLS1.1 and
|
|
above, it's not sufficient to pass SSL_OP_NO_TLSv1, one has to pass
|
|
SSL_OP_NO_TLSv1|SSL_OP_NO_SSLv3|SSL_OP_NO_SSLv2. This applies to
|
|
client side.

Changes between 1.0.1 and 1.0.1a [19 Apr 2012]
|
|
|
|
*) Check for potentially exploitable overflows in asn1_d2i_read_bio
|

BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer
|
|
in CRYPTO_realloc_clean.
|

|
|
(CVE-2012-2110)
|
|
[Adam Langley (Google), Tavis Ormandy, Google Security Team]
|
|
|
|
*) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections.
|
|
[Adam Langley]
|
|
|
|
*) Workarounds for some broken servers that "hang" if a client hello
|
|
record length exceeds 255 bytes.
|
|
|
|
1. Do not use record version number > TLS 1.0 in initial client
|
|
hello: some (but not all) hanging servers will now work.
|
|
2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate
|
|
the number of ciphers sent in the client hello. This should be
|
|
set to an even number, such as 50, for example by passing:
|
|
-DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure.
|
|
Most broken servers should now work.
|
|
3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable
|
|
TLS 1.2 client support entirely.
|
|
[Steve Henson]
|
|
|
|
*) Fix SEGV in Vector Permutation AES module observed in OpenSSH.
|
|
[Andy Polyakov]
|
|
|
|
Changes between 1.0.0h and 1.0.1 [14 Mar 2012]
|
|
|
|
*) Add compatibility with old MDC2 signatures which use an ASN1 OCTET
|
|
STRING form instead of a DigestInfo.
|
|
[Steve Henson]
|
|
|
|
*) The format used for MDC2 RSA signatures is inconsistent between EVP
|
|
and the RSA_sign/RSA_verify functions. This was made more apparent when
|
|
OpenSSL used RSA_sign/RSA_verify for some RSA signatures in particular
|
|
those which went through EVP_PKEY_METHOD in 1.0.0 and later. Detect
|
|
the correct format in RSA_verify so both forms transparently work.
|
|
[Steve Henson]
|
|
|
|
*) Some servers which support TLS 1.0 can choke if we initially indicate
|
|
support for TLS 1.2 and later renegotiate using TLS 1.0 in the RSA
|
|
encrypted premaster secret. As a workaround use the maximum permitted
|
|
client version in client hello, this should keep such servers happy
|
|
and still work with previous versions of OpenSSL.
|
|
[Steve Henson]
|
|
|
|
*) Add support for TLS/DTLS heartbeats.
|
|
[Robin Seggelmann <seggelmann@fh-muenster.de>]
|
|
|
|
*) Add support for SCTP.
|
|
[Robin Seggelmann <seggelmann@fh-muenster.de>]
|
|
|
|
*) Improved PRNG seeding for VOS.
|
|
[Paul Green <Paul.Green@stratus.com>]
|
|
|
|
*) Extensive assembler packs updates, most notably:
|
|
|
|
- x86[_64]: AES-NI, PCLMULQDQ, RDRAND support;
|
|
- x86[_64]: SSSE3 support (SHA1, vector-permutation AES);
|
|
- x86_64: bit-sliced AES implementation;
|
|
- ARM: NEON support, contemporary platforms optimizations;
|
|
- s390x: z196 support;
|
|
- *: GHASH and GF(2^m) multiplication implementations;
|
|
|
|
[Andy Polyakov]
|
|
|
|
*) Make TLS-SRP code conformant with RFC 5054 API cleanup
|
|
(removal of unnecessary code)
|
|
[Peter Sylvester <peter.sylvester@edelweb.fr>]
|
|
|
|
*) Add TLS key material exporter from RFC 5705.
|
|
[Eric Rescorla]
|
|
|
|
*) Add DTLS-SRTP negotiation from RFC 5764.
|
|
[Eric Rescorla]
|
|
|
|
*) Add Next Protocol Negotiation,
|
|
http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00. Can be
|
|
disabled with a no-npn flag to config or Configure. Code donated
|
|
by Google.
|
|
[Adam Langley <agl@google.com> and Ben Laurie]
|
|
|
|
*) Add optional 64-bit optimized implementations of elliptic curves NIST-P224,
|
|
NIST-P256, NIST-P521, with constant-time single point multiplication on
|
|
typical inputs. Compiler support for the nonstandard type __uint128_t is
|
|
required to use this (present in gcc 4.4 and later, for 64-bit builds).
|
|
Code made available under Apache License version 2.0.
|
|
|
|
Specify "enable-ec_nistp_64_gcc_128" on the Configure (or config) command
|
|
line to include this in your build of OpenSSL, and run "make depend" (or
|
|
"make update"). This enables the following EC_METHODs:
|
|
|
|
EC_GFp_nistp224_method()
|
|
EC_GFp_nistp256_method()
|
|
EC_GFp_nistp521_method()
|
|
|
|
EC_GROUP_new_by_curve_name() will automatically use these (while
|
|
EC_GROUP_new_curve_GFp() currently prefers the more flexible
|
|
implementations).
|
|
[Emilia Käsper, Adam Langley, Bodo Moeller (Google)]
|
|
|
|
*) Use type ossl_ssize_t instead of ssize_t which isn't available on
|
|
all platforms. Move ssize_t definition from e_os.h to the public
|
|
header file e_os2.h as it now appears in public header file cms.h
|
|
[Steve Henson]
|
|
|
|
*) New -sigopt option to the ca, req and x509 utilities. Additional
|
|
signature parameters can be passed using this option and in
|
|
particular PSS.
|
|
[Steve Henson]
|
|
|
|
*) Add RSA PSS signing function. This will generate and set the
|
|
appropriate AlgorithmIdentifiers for PSS based on those in the
|
|
corresponding EVP_MD_CTX structure. No application support yet.
|
|
[Steve Henson]
|
|
|
|
*) Support for companion algorithm specific ASN1 signing routines.
|
|
New function ASN1_item_sign_ctx() signs a pre-initialised
|
|
EVP_MD_CTX structure and sets AlgorithmIdentifiers based on
|
|
the appropriate parameters.
|
|
[Steve Henson]
|
|
|
|
*) Add new algorithm specific ASN1 verification initialisation function
|
|
to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1
|
|
handling will be the same no matter what EVP_PKEY_METHOD is used.
|
|
Add a PSS handler to support verification of PSS signatures: checked
|
|
against a number of sample certificates.
|
|
[Steve Henson]
|
|
|
|
*) Add signature printing for PSS. Add PSS OIDs.
|
|
[Steve Henson, Martin Kaiser <lists@kaiser.cx>]
|
|
|
|
*) Add algorithm specific signature printing. An individual ASN1 method
|
|
can now print out signatures instead of the standard hex dump.
|
|
|
|
More complex signatures (e.g. PSS) can print out more meaningful
|
|
information. Include DSA version that prints out the signature
|
|
parameters r, s.
|
|
[Steve Henson]
|
|
|
|
*) Password based recipient info support for CMS library: implementing
|
|
RFC3211.
|
|
[Steve Henson]
|
|
|
|
*) Split password based encryption into PBES2 and PBKDF2 functions. This
|
|
neatly separates the code into cipher and PBE sections and is required
|
|
for some algorithms that split PBES2 into separate pieces (such as
|
|
password based CMS).
|
|
[Steve Henson]
|
|
|
|
*) Session-handling fixes:
|
|
- Fix handling of connections that are resuming with a session ID,
|
|
but also support Session Tickets.
|
|
- Fix a bug that suppressed issuing of a new ticket if the client
|
|
presented a ticket with an expired session.
|
|
- Try to set the ticket lifetime hint to something reasonable.
|
|
- Make tickets shorter by excluding irrelevant information.
|
|
- On the client side, don't ignore renewed tickets.
|
|
[Adam Langley, Bodo Moeller (Google)]
|
|
|
|
*) Fix PSK session representation.
|
|
[Bodo Moeller]
|
|
|
|
*) Add RC4-MD5 and AESNI-SHA1 "stitched" implementations.
|
|
|
|
This work was sponsored by Intel.
|
|
[Andy Polyakov]
|
|
|
|
*) Add GCM support to TLS library. Some custom code is needed to split
|
|
the IV between the fixed (from PRF) and explicit (from TLS record)
|
|
portions. This adds all GCM ciphersuites supported by RFC5288 and
|
|
RFC5289. Generalise some AES* cipherstrings to include GCM and
|
|
add a special AESGCM string for GCM only.
|
|
[Steve Henson]
|
|
|
|
*) Expand range of ctrls for AES GCM. Permit setting invocation
|
|
field on decrypt and retrieval of invocation field only on encrypt.
|
|
[Steve Henson]
|
|
|
|
*) Add HMAC ECC ciphersuites from RFC5289. Include SHA384 PRF support.
|
|
As required by RFC5289 these ciphersuites cannot be used if for
|
|
versions of TLS earlier than 1.2.
|
|
[Steve Henson]
|
|
|
|
*) For FIPS capable OpenSSL interpret a NULL default public key method
|
|
as unset and return the appropriate default but do *not* set the default.
|
|
This means we can return the appropriate method in applications that
|
|
switch between FIPS and non-FIPS modes.
|
|
[Steve Henson]
|
|
|
|
*) Redirect HMAC and CMAC operations to FIPS module in FIPS mode. If an
|
|
ENGINE is used then we cannot handle that in the FIPS module so we
|
|
keep original code iff non-FIPS operations are allowed.
|
|
[Steve Henson]
|
|
|
|
*) Add -attime option to openssl utilities.
|
|
[Peter Eckersley <pde@eff.org>, Ben Laurie and Steve Henson]
|
|
|
|
*) Redirect DSA and DH operations to FIPS module in FIPS mode.
|
|
[Steve Henson]
|
|
|
|
*) Redirect ECDSA and ECDH operations to FIPS module in FIPS mode. Also use
|
|
FIPS EC methods unconditionally for now.
|
|
[Steve Henson]
|
|
|
|
*) New build option no-ec2m to disable characteristic 2 code.
|
|
[Steve Henson]
|
|
|
|
*) Backport libcrypto audit of return value checking from 1.1.0-dev; not
|
|
all cases can be covered as some introduce binary incompatibilities.
|
|
[Steve Henson]
|
|
|
|
*) Redirect RSA operations to FIPS module including keygen,
|
|
encrypt, decrypt, sign and verify. Block use of non FIPS RSA methods.
|
|
[Steve Henson]
|
|
|
|
*) Add similar low level API blocking to ciphers.
|
|
[Steve Henson]
|
|
|
|
*) Low level digest APIs are not approved in FIPS mode: any attempt
|
|
to use these will cause a fatal error. Applications that *really* want
|
|
to use them can use the private_* version instead.
|
|
[Steve Henson]
|
|
|
|
*) Redirect cipher operations to FIPS module for FIPS builds.
|
|
[Steve Henson]
|
|
|
|
*) Redirect digest operations to FIPS module for FIPS builds.
|
|
[Steve Henson]
|
|
|
|
*) Update build system to add "fips" flag which will link in fipscanister.o
|
|
for static and shared library builds embedding a signature if needed.
|
|
[Steve Henson]
|
|
|
|
*) Output TLS supported curves in preference order instead of numerical
|
|
order. This is currently hardcoded for the highest order curves first.
|
|
This should be configurable so applications can judge speed vs strength.
|
|
[Steve Henson]
|
|
|
|
*) Add TLS v1.2 server support for client authentication.
|
|
[Steve Henson]
|
|
|
|
*) Add support for FIPS mode in ssl library: disable SSLv3, non-FIPS ciphers
|
|
and enable MD5.
|
|
[Steve Henson]
|
|
|
|
*) Functions FIPS_mode_set() and FIPS_mode() which call the underlying
|
|
FIPS modules versions.
|
|
[Steve Henson]
|
|
|
|
*) Add TLS v1.2 client side support for client authentication. Keep cache
|
|
of handshake records longer as we don't know the hash algorithm to use
|
|
until after the certificate request message is received.
|
|
[Steve Henson]
|
|
|
|
*) Initial TLS v1.2 client support. Add a default signature algorithms
|
|
extension including all the algorithms we support. Parse new signature
|
|
format in client key exchange. Relax some ECC signing restrictions for
|
|
TLS v1.2 as indicated in RFC5246.
|
|
[Steve Henson]
|
|
|
|
*) Add server support for TLS v1.2 signature algorithms extension. Switch
|
|
to new signature format when needed using client digest preference.
|
|
All server ciphersuites should now work correctly in TLS v1.2. No client
|
|
support yet and no support for client certificates.
|
|
[Steve Henson]
|
|
|
|
*) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch
|
|
to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based
|
|
ciphersuites. At present only RSA key exchange ciphersuites work with
|
|
TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete
|
|
SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods
|
|
and version checking.
|
|
[Steve Henson]
|
|
|
|
*) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled
|
|
with this defined it will not be affected by any changes to ssl internal
|
|
structures. Add several utility functions to allow openssl application
|
|
to work with OPENSSL_NO_SSL_INTERN defined.
|
|
[Steve Henson]
|
|
|
|
*) A long standing patch to add support for SRP from EdelWeb (Peter
|
|
Sylvester and Christophe Renou) was integrated.
|
|
[Christophe Renou <christophe.renou@edelweb.fr>, Peter Sylvester
|
|
<peter.sylvester@edelweb.fr>, Tom Wu <tjw@cs.stanford.edu>, and
|
|
Ben Laurie]
|
|
|
|
*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
|
|
[Steve Henson]
|
|
|
|
*) Permit abbreviated handshakes when renegotiating using the function
|
|
SSL_renegotiate_abbreviated().
|
|
[Robin Seggelmann <seggelmann@fh-muenster.de>]
|
|
|
|
*) Add call to ENGINE_register_all_complete() to
|
|
ENGINE_load_builtin_engines(), so some implementations get used
|
|
automatically instead of needing explicit application support.
|
|
[Steve Henson]
|
|
|
|
*) Add support for TLS key exporter as described in RFC5705.
|
|
[Robin Seggelmann <seggelmann@fh-muenster.de>, Steve Henson]
|
|
|
|
*) Initial TLSv1.1 support. Since TLSv1.1 is very similar to TLS v1.0 only
|
|
a few changes are required:
|
|
|
|
Add SSL_OP_NO_TLSv1_1 flag.
|
|
Add TLSv1_1 methods.
|
|
Update version checking logic to handle version 1.1.
|
|
Add explicit IV handling (ported from DTLS code).
|
|
Add command line options to s_client/s_server.
|
|
[Steve Henson]
|
|
|
|
Changes between 1.0.0g and 1.0.0h [12 Mar 2012]
|
|
|
|
*) Fix MMA (Bleichenbacher's attack on PKCS #1 v1.5 RSA padding) weakness
|
|
in CMS and PKCS7 code. When RSA decryption fails use a random key for
|
|
content decryption and always return the same error. Note: this attack
|
|
needs on average 2^20 messages so it only affects automated senders. The
|
|
old behaviour can be re-enabled in the CMS code by setting the
|
|
CMS_DEBUG_DECRYPT flag: this is useful for debugging and testing where
|
|
an MMA defence is not necessary.

Thanks to Ivan Nestlerode <inestlerode@us.ibm.com> for discovering
|
|
this issue. (CVE-2012-0884)
|
|
[Steve Henson]
|
|
|
|
*) Fix CVE-2011-4619: make sure we really are receiving a
|
|
client hello before rejecting multiple SGC restarts. Thanks to
|
|
Ivan Nestlerode <inestlerode@us.ibm.com> for discovering this bug.

Changes between 1.0.0f and 1.0.0g [18 Jan 2012]
|
|
|
|
*) Fix for DTLS DoS issue introduced by fix for CVE-2011-4109.
|
|
Thanks to Antonio Martin, Enterprise Secure Access Research and
|
|
Development, Cisco Systems, Inc. for discovering this bug and
|

preparing a fix. (CVE-2012-0050)
|
|
[Antonio Martin]
|
|
|
|
Changes between 1.0.0e and 1.0.0f [4 Jan 2012]
|
|
|
|
*) Nadhem Alfardan and Kenny Paterson have discovered an extension
|
|
of the Vaudenay padding oracle attack on CBC mode encryption
|
|
which enables an efficient plaintext recovery attack against
|
|
the OpenSSL implementation of DTLS. Their attack exploits timing
|
|
differences arising during decryption processing. A research
|
|
paper describing this attack can be found at:
|
|
http://www.isg.rhul.ac.uk/~kp/dtls.pdf
|
|
Thanks go to Nadhem Alfardan and Kenny Paterson of the Information
|
|
Security Group at Royal Holloway, University of London
|
|
(www.isg.rhul.ac.uk) for discovering this flaw and to Robin Seggelmann
|
|
<seggelmann@fh-muenster.de> and Michael Tuexen <tuexen@fh-muenster.de>
|
|
for preparing the fix. (CVE-2011-4108)
|
|
[Robin Seggelmann, Michael Tuexen]
|
|
|
|
*) Clear bytes used for block padding of SSL 3.0 records.
|
|
(CVE-2011-4576)
|
|
[Adam Langley (Google)]
|
|
|
|
*) Only allow one SGC handshake restart for SSL/TLS. Thanks to George
|
|
Kadianakis <desnacked@gmail.com> for discovering this issue and
|
|
Adam Langley for preparing the fix. (CVE-2011-4619)
|
|
[Adam Langley (Google)]
|
|
|
|
*) Check parameters are not NULL in GOST ENGINE. (CVE-2012-0027)
|
|
[Andrey Kulikov <amdeich@gmail.com>]
|
|
|
|
*) Prevent malformed RFC3779 data triggering an assertion failure.
|
|
Thanks to Andrew Chi, BBN Technologies, for discovering the flaw
|
|
and Rob Austein <sra@hactrn.net> for fixing it. (CVE-2011-4577)
|
|
[Rob Austein <sra@hactrn.net>]
|
|
|
|
*) Improved PRNG seeding for VOS.
|
|
[Paul Green <Paul.Green@stratus.com>]
|
|
|
|
*) Fix ssl_ciph.c set-up race.
|
|
[Adam Langley (Google)]
|
|
|
|
*) Fix spurious failures in ecdsatest.c.
|
|
[Emilia Käsper (Google)]
|
|
|
|
*) Fix the BIO_f_buffer() implementation (which was mixing different
|
|
interpretations of the '..._len' fields).
|
|
[Adam Langley (Google)]
|
|
|
|
*) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than
|
|
BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent
|
|
threads won't reuse the same blinding coefficients.
|
|
|
|
This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING
|
|
lock to call BN_BLINDING_invert_ex, and avoids one use of
|
|
BN_BLINDING_update for each BN_BLINDING structure (previously,
|
|
the last update always remained unused).
|
|
[Emilia Käsper (Google)]
|
|
|
|
*) In ssl3_clear, preserve s3->init_extra along with s3->rbuf.
|
|
[Bob Buckholz (Google)]
|
|
|
|
Changes between 1.0.0d and 1.0.0e [6 Sep 2011]
|
|
|
|
*) Fix bug where CRLs with nextUpdate in the past are sometimes accepted
|
|
by initialising X509_STORE_CTX properly. (CVE-2011-3207)
|
|
[Kaspar Brand <ossl@velox.ch>]
|
|
|
|
*) Fix SSL memory handling for (EC)DH ciphersuites, in particular
|
|
for multi-threaded use of ECDH. (CVE-2011-3210)
|
|
[Adam Langley (Google)]
|
|
|
|
*) Fix x509_name_ex_d2i memory leak on bad inputs.
|
|
[Bodo Moeller]
|
|
|
|
*) Remove hard coded ecdsaWithSHA1 signature tests in ssl code and check
|
|
signature public key algorithm by using OID xref utilities instead.
|
|
Before this you could only use some ECC ciphersuites with SHA1 only.
|
|
[Steve Henson]
|
|
|
|
*) Add protection against ECDSA timing attacks as mentioned in the paper
|
|
by Billy Bob Brumley and Nicola Tuveri, see:
|
|
|
|
http://eprint.iacr.org/2011/232.pdf

|
|
Changes between 1.0.0c and 1.0.0d [8 Feb 2011]
|
|
|
|
*) Fix parsing of OCSP stapling ClientHello extension. CVE-2011-0014
|
|
[Neel Mehta, Adam Langley, Bodo Moeller (Google)]
|
|
|
|
*) Fix bug in string printing code: if *any* escaping is enabled we must
|
|
escape the escape character (backslash) or the resulting string is
|
|
ambiguous.
|
|
[Steve Henson]
|
|
|
|
Changes between 1.0.0b and 1.0.0c [2 Dec 2010]
|
|
|
|
*) Disable code workaround for ancient and obsolete Netscape browsers
|
|
and servers: an attacker can use it in a ciphersuite downgrade attack.
|
|
Thanks to Martin Rex for discovering this bug. CVE-2010-4180
|
|
[Steve Henson]
|
|
|
|
*) Fixed J-PAKE implementation error, originally discovered by
|
|
Sebastien Martini, further info and confirmation from Stefan
|
|
Arentz and Feng Hao. Note that this fix is a security fix. CVE-2010-4252
|
|
[Ben Laurie]
|
|
|
|
Changes between 1.0.0a and 1.0.0b [16 Nov 2010]
|
|
|
|
*) Fix extension code to avoid race conditions which can result in a buffer
|
|
overrun vulnerability: resumed sessions must not be modified as they can
|
|
be shared by multiple threads. CVE-2010-3864
|
|
[Steve Henson]
|
|
|
|
*) Fix WIN32 build system to correctly link an ENGINE directory into
|
|
a DLL.
|
|
[Steve Henson]
|
|
|
|
Changes between 1.0.0 and 1.0.0a [01 Jun 2010]
|
|
|
|
*) Check return value of int_rsa_verify in pkey_rsa_verifyrecover
|
|
(CVE-2010-1633)
|
|
[Steve Henson, Peter-Michael Hager <hager@dortmund.net>]
|
|
|
|
Changes between 0.9.8n and 1.0.0 [29 Mar 2010]
|
|
|
|
*) Add "missing" function EVP_CIPHER_CTX_copy(). This copies a cipher
|
|
context. The operation can be customised via the ctrl mechanism in
|
|
case ENGINEs want to include additional functionality.
|
|
[Steve Henson]
|
|
|
|
*) Tolerate yet another broken PKCS#8 key format: private key value negative.
|
|
[Steve Henson]
|
|
|
|
*) Add new -subject_hash_old and -issuer_hash_old options to x509 utility to
|
|
output hashes compatible with older versions of OpenSSL.
|
|
[Willy Weisz <weisz@vcpc.univie.ac.at>]
|
|
|
|
*) Fix compression algorithm handling: if resuming a session use the
|
|
compression algorithm of the resumed session instead of determining
|
|
it from client hello again. Don't allow server to change algorithm.
|
|
[Steve Henson]
|
|
|
|
*) Add load_crls() function to apps tidying load_certs() too. Add option
|
|
to verify utility to allow additional CRLs to be included.
|
|
[Steve Henson]
|
|
|
|
*) Update OCSP request code to permit adding custom headers to the request:
|
|
some responders need this.
|
|
[Steve Henson]
|
|
|
|
*) The function EVP_PKEY_sign() returns <=0 on error: check return code
|
|
correctly.
|
|
[Julia Lawall <julia@diku.dk>]
|
|
|
|
*) Update verify callback code in apps/s_cb.c and apps/verify.c, it
|
|
needlessly dereferenced structures, used obsolete functions and
|
|
didn't handle all updated verify codes correctly.
|
|
[Steve Henson]
|
|
|
|
*) Disable MD2 in the default configuration.
|
|
[Steve Henson]
|
|
|
|
*) In BIO_pop() and BIO_push() use the ctrl argument (which was NULL) to
|
|
indicate the initial BIO being pushed or popped. This makes it possible
|
|
to determine whether the BIO is the one explicitly called or as a result
|
|
of the ctrl being passed down the chain. Fix BIO_pop() and SSL BIOs so
|
|
it handles reference counts correctly and doesn't zero out the I/O bio
|
|
when it is not being explicitly popped. WARNING: applications which
|
|
included workarounds for the old buggy behaviour will need to be modified
|
|
or they could free up already freed BIOs.
|
|
[Steve Henson]
|
|
|
|
*) Extend the uni2asc/asc2uni => OPENSSL_uni2asc/OPENSSL_asc2uni
|
|
renaming to all platforms (within the 0.9.8 branch, this was
|
|
done conditionally on Netware platforms to avoid a name clash).
|
|
[Guenter <lists@gknw.net>]
|
|
|
|
*) Add ECDHE and PSK support to DTLS.
|
|
[Michael Tuexen <tuexen@fh-muenster.de>]
|
|
|
|
*) Add CHECKED_STACK_OF macro to safestack.h, otherwise safestack can't
|
|
be used on C++.
|
|
[Steve Henson]
|
|
|
|
*) Add "missing" function EVP_MD_flags() (without this the only way to
|
|
retrieve a digest flags is by accessing the structure directly. Update
|
|
EVP_MD_do_all*() and EVP_CIPHER_do_all*() to include the name a digest
|
|
or cipher is registered as in the "from" argument. Print out all
|
|
registered digests in the dgst usage message instead of manually
|
|
attempting to work them out.
|
|
[Steve Henson]
|
|
|
|
*) If no SSLv2 ciphers are used don't use an SSLv2 compatible client hello:
|
|
this allows the use of compression and extensions. Change default cipher
|
|
string to remove SSLv2 ciphersuites. This effectively avoids ancient SSLv2
|
|
by default unless an application cipher string requests it.
|
|
[Steve Henson]
|
|
|
|
*) Alter match criteria in PKCS12_parse(). It used to try to use local
|
|
key ids to find matching certificates and keys but some PKCS#12 files
|
|
don't follow the (somewhat unwritten) rules and this strategy fails.
|
|
Now just gather all certificates together and the first private key
|
|
then look for the first certificate that matches the key.
|
|
[Steve Henson]
|
|
|
|
*) Support use of registered digest and cipher names for dgst and cipher
|
|
commands instead of having to add each one as a special case. So now
|
|
you can do:
|
|
|
|
openssl sha256 foo
|
|
|
|
as well as:
|
|
|
|
openssl dgst -sha256 foo
|
|
|
|
and this works for ENGINE based algorithms too.
|
|
|
|
[Steve Henson]
|
|
|
|
*) Update Gost ENGINE to support parameter files.
|
|
[Victor B. Wagner <vitus@cryptocom.ru>]
|
|
|
|
*) Support GeneralizedTime in ca utility.
|
|
[Oliver Martin <oliver@volatilevoid.net>, Steve Henson]
|
|
|
|
*) Enhance the hash format used for certificate directory links. The new
|
|
form uses the canonical encoding (meaning equivalent names will work
|
|
even if they aren't identical) and uses SHA1 instead of MD5. This form
|
|
is incompatible with the older format and as a result c_rehash should
|
|
be used to rebuild symbolic links.
|
|
[Steve Henson]
|
|
|
|
*) Make PKCS#8 the default write format for private keys, replacing the
|
|
traditional format. This form is standardised, more secure and doesn't
|
|
include an implicit MD5 dependency.
|
|
[Steve Henson]
|
|
|
|
*) Add a $gcc_devteam_warn option to Configure. The idea is that any code
|
|
committed to OpenSSL should pass this lot as a minimum.
|
|
[Steve Henson]
|
|
|
|
*) Add session ticket override functionality for use by EAP-FAST.
|
|
[Jouni Malinen <j@w1.fi>]
|
|
|
|
*) Modify HMAC functions to return a value. Since these can be implemented
|
|
in an ENGINE errors can occur.
|
|
[Steve Henson]
|
|
|
|
*) Type-checked OBJ_bsearch_ex.
|
|
[Ben Laurie]
|
|
|
|
*) Type-checked OBJ_bsearch. Also some constification necessitated
|
|
by type-checking. Still to come: TXT_DB, bsearch(?),
|
|
OBJ_bsearch_ex, qsort, CRYPTO_EX_DATA, ASN1_VALUE, ASN1_STRING,
|
|
CONF_VALUE.
|
|
[Ben Laurie]
|
|
|
|
*) New function OPENSSL_gmtime_adj() to add a specific number of days and
|
|
seconds to a tm structure directly, instead of going through OS
|
|
specific date routines. This avoids any issues with OS routines such
|
|
as the year 2038 bug. New *_adj() functions for ASN1 time structures
|
|
and X509_time_adj_ex() to cover the extended range. The existing
|
|
X509_time_adj() is still usable and will no longer have any date issues.
|
|
[Steve Henson]
|
|
|
|
*) Delta CRL support. New use deltas option which will attempt to locate
|
|
and search any appropriate delta CRLs available.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Support for CRLs partitioned by reason code. Reorganise CRL processing
|
|
code and add additional score elements. Validate alternate CRL paths
|
|
as part of the CRL checking and indicate a new error "CRL path validation
|
|
error" in this case. Applications wanting additional details can use
|
|
the verify callback and check the new "parent" field. If this is not
|
|
NULL CRL path validation is taking place. Existing applications won't
|
|
see this because it requires extended CRL support which is off by
|
|
default.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Support for freshest CRL extension.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Initial indirect CRL support. Currently only supported in the CRLs
|
|
passed directly and not via lookup. Process certificate issuer
|
|
CRL entry extension and lookup CRL entries by bother issuer name
|
|
and serial number. Check and process CRL issuer entry in IDP extension.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Add support for distinct certificate and CRL paths. The CRL issuer
|
|
certificate is validated separately in this case. Only enabled if
|
|
an extended CRL support flag is set: this flag will enable additional
|
|
CRL functionality in future.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Add support for policy mappings extension.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Fixes to pathlength constraint, self issued certificate handling,
|
|
policy processing to align with RFC3280 and PKITS tests.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Support for name constraints certificate extension. DN, email, DNS
|
|
and URI types are currently supported.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) To cater for systems that provide a pointer-based thread ID rather
|
|
than numeric, deprecate the current numeric thread ID mechanism and
|
|
replace it with a structure and associated callback type. This
|
|
mechanism allows a numeric "hash" to be extracted from a thread ID in
|
|
either case, and on platforms where pointers are larger than 'long',
|
|
mixing is done to help ensure the numeric 'hash' is usable even if it
|
|
can't be guaranteed unique. The default mechanism is to use "&errno"
|
|
as a pointer-based thread ID to distinguish between threads.
|
|
|
|
Applications that want to provide their own thread IDs should now use
|
|
CRYPTO_THREADID_set_callback() to register a callback that will call
|
|
either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer().
|
|
|
|
Note that ERR_remove_state() is now deprecated, because it is tied
|
|
to the assumption that thread IDs are numeric. ERR_remove_state(0)
|
|
to free the current thread's error state should be replaced by
|
|
ERR_remove_thread_state(NULL).
|
|
|
|
(This new approach replaces the functions CRYPTO_set_idptr_callback(),
|
|
CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in
|
|
OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an
|
|
application was previously providing a numeric thread callback that
|
|
was inappropriate for distinguishing threads, then uniqueness might
|
|
have been obtained with &errno that happened immediately in the
|
|
intermediate development versions of OpenSSL; this is no longer the
|
|
case, the numeric thread callback will now override the automatic use
|
|
of &errno.)

*) Initial support for different CRL issuing certificates. This covers a
|

[Steve Henson]
|
|
|
|
*) Removed effectively defunct crypto/store from the build.
|
|
[Ben Laurie]
|
|
|
|
*) Revamp of STACK to provide stronger type-checking. Still to come:
|
|
TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE,
|
|
ASN1_STRING, CONF_VALUE.
|
|
[Ben Laurie]
|
|
|
|
*) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer
|
|
RAM on SSL connections. This option can save about 34k per idle SSL.
|
|
[Nick Mathewson]
|
|
|
|
*) Revamp of LHASH to provide stronger type-checking. Still to come:
|
|
STACK, TXT_DB, bsearch, qsort.
|
|
[Ben Laurie]
|
|
|
|
*) Initial support for Cryptographic Message Syntax (aka CMS) based
|
|
on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility,
|
|
support for data, signedData, compressedData, digestedData and
|
|
encryptedData, envelopedData types included. Scripts to check against
|
|
RFC4134 examples draft and interop and consistency checks of many
|
|
content types and variants.
|
|
[Steve Henson]
|
|
|
|
*) Add options to enc utility to support use of zlib compression BIO.
|
|
[Steve Henson]
|
|
|
|
*) Extend mk1mf to support importing of options and assembly language
|
|
files from Configure script, currently only included in VC-WIN32.
|
|
The assembly language rules can now optionally generate the source
|
|
files from the associated perl scripts.
|
|
[Steve Henson]
|
|
|
|
*) Implement remaining functionality needed to support GOST ciphersuites.
|
|
Interop testing has been performed using CryptoPro implementations.
|

[Victor B. Wagner <vitus@cryptocom.ru>]
|
|
|
|
*) s390x assembler pack.
|
|
[Andy Polyakov]
|
|
|
|
*) ARMv4 assembler pack. ARMv4 refers to v4 and later ISA, not CPU
|
|
"family."
|
|
[Andy Polyakov]
|
|
|
|
*) Implement Opaque PRF Input TLS extension as specified in
|
|
draft-rescorla-tls-opaque-prf-input-00.txt. Since this is not an
|
|
official specification yet and no extension type assignment by
|
|
IANA exists, this extension (for now) will have to be explicitly
|
|
enabled when building OpenSSL by providing the extension number
|
|
to use. For example, specify an option
|
|
|
|
-DTLSEXT_TYPE_opaque_prf_input=0x9527
|
|
|
|
to the "config" or "Configure" script to enable the extension,
|
|
assuming extension number 0x9527 (which is a completely arbitrary
|
|
and unofficial assignment based on the MD5 hash of the Internet
|
|
Draft). Note that by doing so, you potentially lose
|
|
interoperability with other TLS implementations since these might
|
|
be using the same extension number for other purposes.
|
|
|
|
SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the
|
|
opaque PRF input value to use in the handshake. This will create
|
|
an internal copy of the length-'len' string at 'src', and will
|
|
return non-zero for success.
|
|
|
|
To get more control and flexibility, provide a callback function
|
|
by using
|
|
|
|
SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb)
|
|
SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg)
|
|
|
|
where
|
|
|
|
int (*cb)(SSL *, void *peerinput, size_t len, void *arg);
|
|
void *arg;
|
|
|
|
Callback function 'cb' will be called in handshakes, and is
|
|
expected to use SSL_set_tlsext_opaque_prf_input() as appropriate.
|
|
Argument 'arg' is for application purposes (the value as given to
|
|
SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly
|
|
be provided to the callback function). The callback function
|
|
has to return non-zero to report success: usually 1 to use opaque
|
|
PRF input just if possible, or 2 to enforce use of the opaque PRF
|
|
input. In the latter case, the library will abort the handshake
|
|
if opaque PRF input is not successfully negotiated.
|
|
|
|
Arguments 'peerinput' and 'len' given to the callback function
|
|
will always be NULL and 0 in the case of a client. A server will
|
|
see the client's opaque PRF input through these variables if
|
|
available (NULL and 0 otherwise). Note that if the server
|
|
provides an opaque PRF input, the length must be the same as the
|
|
length of the client's opaque PRF input.
|
|
|
|
Note that the callback function will only be called when creating
|
|
a new session (session resumption can resume whatever was
|
|
previously negotiated), and will not be called in SSL 2.0
|
|
handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or
|
|
SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended
|
|
for applications that need to enforce opaque PRF input.
|
|
|
|
[Bodo Moeller]
|
|
|
|
*) Update ssl code to support digests other than SHA1+MD5 for handshake
|
|
MAC.
|
|
|
|
[Victor B. Wagner <vitus@cryptocom.ru>]
|
|
|
|
*) Add RFC4507 support to OpenSSL. This includes the corrections in
|
|
RFC4507bis. The encrypted ticket format is an encrypted encoded
|
|
SSL_SESSION structure, that way new session features are automatically
|
|
supported.
|
|
|
|
If a client application caches session in an SSL_SESSION structure
|
|
support is transparent because tickets are now stored in the encoded
|
|
SSL_SESSION.
|
|
|
|
The SSL_CTX structure automatically generates keys for ticket
|
|
protection in servers so again support should be possible
|
|
with no application modification.
|
|
|
|
If a client or server wishes to disable RFC4507 support then the option
|
|
SSL_OP_NO_TICKET can be set.
|
|
|
|
Add a TLS extension debugging callback to allow the contents of any client
|
|
or server extensions to be examined.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Final changes to avoid use of pointer pointer casts in OpenSSL.
|
|
OpenSSL should now compile cleanly on gcc 4.2
|
|
[Peter Hartley <pdh@utter.chaos.org.uk>, Steve Henson]
|
|
|
|
*) Update SSL library to use new EVP_PKEY MAC API. Include generic MAC
|
|
support including streaming MAC support: this is required for GOST
|
|
ciphersuite support.
|
|
[Victor B. Wagner <vitus@cryptocom.ru>, Steve Henson]
|
|
|
|
*) Add option -stream to use PKCS#7 streaming in smime utility. New
|
|
function i2d_PKCS7_bio_stream() and PEM_write_PKCS7_bio_stream()
|
|
to output in BER and PEM format.
|
|
[Steve Henson]
|
|
|
|
*) Experimental support for use of HMAC via EVP_PKEY interface. This
|
|
allows HMAC to be handled via the EVP_DigestSign*() interface. The
|
|
EVP_PKEY "key" in this case is the HMAC key, potentially allowing
|
|
ENGINE support for HMAC keys which are unextractable. New -mac and
|
|
-macopt options to dgst utility.
|
|
[Steve Henson]
|
|
|
|
*) New option -sigopt to dgst utility. Update dgst to use
|
|
EVP_Digest{Sign,Verify}*. These two changes make it possible to use
|
|
alternative signing parameters such as X9.31 or PSS in the dgst
|
|
utility.
|
|
[Steve Henson]
|
|
|
|
*) Change ssl_cipher_apply_rule(), the internal function that does
|
|
the work each time a ciphersuite string requests enabling
|
|
("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or
|
|
removing ("!foo+bar") a class of ciphersuites: Now it maintains
|
|
the order of disabled ciphersuites such that those ciphersuites
|
|
that most recently went from enabled to disabled not only stay
|
|
in order with respect to each other, but also have higher priority
|
|
than other disabled ciphersuites the next time ciphersuites are
|
|
enabled again.
|
|
|
|
This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable
|
|
the same ciphersuites as with "HIGH" alone, but in a specific
|
|
order where the PSK ciphersuites come first (since they are the
|
|
most recently disabled ciphersuites when "HIGH" is parsed).
|
|
|
|
Also, change ssl_create_cipher_list() (using this new
|
|
functionality) such that between otherwise identical
|
|
ciphersuites, ephemeral ECDH is preferred over ephemeral DH in
|
|
the default order.
|
|
[Bodo Moeller]
|
|
|
|
*) Change ssl_create_cipher_list() so that it automatically
|
|
arranges the ciphersuites in reasonable order before starting
|
|
to process the rule string. Thus, the definition for "DEFAULT"
|
|
(SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but
|
|
remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH".
|
|
This makes it much easier to arrive at a reasonable default order
|
|
in applications for which anonymous ciphers are OK (meaning
|
|
that you can't actually use DEFAULT).
|
|
[Bodo Moeller; suggested by Victor Duchovni]
|
|
|
|
*) Split the SSL/TLS algorithm mask (as used for ciphersuite string
|
|
processing) into multiple integers instead of setting
|
|
"SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK",
|
|
"SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer.
|
|
(These masks as well as the individual bit definitions are hidden
|
|
away into the non-exported interface ssl/ssl_locl.h, so this
|
|
change to the definition of the SSL_CIPHER structure shouldn't
|
|
affect applications.) This give us more bits for each of these
|
|
categories, so there is no longer a need to coagulate AES128 and
|
|
AES256 into a single algorithm bit, and to coagulate Camellia128
|
|
and Camellia256 into a single algorithm bit, which has led to all
|
|
kinds of kludges.
|
|
|
|
Thus, among other things, the kludge introduced in 0.9.7m and
|
|
0.9.8e for masking out AES256 independently of AES128 or masking
|
|
out Camellia256 independently of AES256 is not needed here in 0.9.9.
|
|
|
|
With the change, we also introduce new ciphersuite aliases that
|
|
so far were missing: "AES128", "AES256", "CAMELLIA128", and
|
|
"CAMELLIA256".
|
|
[Bodo Moeller]
|
|
|
|
*) Add support for dsa-with-SHA224 and dsa-with-SHA256.
|
|
Use the leftmost N bytes of the signature input if the input is
|
|
larger than the prime q (with N being the size in bytes of q).
|
|
[Nils Larsch]
|
|
|
|
*) Very *very* experimental PKCS#7 streaming encoder support. Nothing uses
|
|
it yet and it is largely untested.
|
|
[Steve Henson]
|
|
|
|
*) Add support for the ecdsa-with-SHA224/256/384/512 signature types.
|
|
[Nils Larsch]
|
|
|
|
*) Initial incomplete changes to avoid need for function casts in OpenSSL
|
|
some compilers (gcc 4.2 and later) reject their use. Safestack is
|
|
reimplemented. Update ASN1 to avoid use of legacy functions.
|
|
[Steve Henson]
|
|
|
|
*) Win32/64 targets are linked with Winsock2.
|
|
[Andy Polyakov]
|
|
|
|
*) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected
|
|
to external functions. This can be used to increase CRL handling
|
|
efficiency especially when CRLs are very large by (for example) storing
|
|
the CRL revoked certificates in a database.
|
|
[Steve Henson]
|
|
|
|
*) Overhaul of by_dir code. Add support for dynamic loading of CRLs so
|
|
new CRLs added to a directory can be used. New command line option
|
|
-verify_return_error to s_client and s_server. This causes real errors
|
|
to be returned by the verify callback instead of carrying on no matter
|
|
what. This reflects the way a "real world" verify callback would behave.
|
|
[Steve Henson]
|
|
|
|
*) GOST engine, supporting several GOST algorithms and public key formats.
|
|
Kindly donated by Cryptocom.
|
|
[Cryptocom]
|
|
|
|
*) Partial support for Issuing Distribution Point CRL extension. CRLs
|
|
partitioned by DP are handled but no indirect CRL or reason partitioning
|
|
(yet). Complete overhaul of CRL handling: now the most suitable CRL is
|
|
selected via a scoring technique which handles IDP and AKID in CRLs.
|
|
[Steve Henson]
|
|
|
|
*) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which
|
|
will ultimately be used for all verify operations: this will remove the
|
|
X509_STORE dependency on certificate verification and allow alternative
|
|
lookup methods. X509_STORE based implementations of these two callbacks.
|
|
[Steve Henson]
|
|
|
|
*) Allow multiple CRLs to exist in an X509_STORE with matching issuer names.
|
|
Modify get_crl() to find a valid (unexpired) CRL if possible.
|
|
[Steve Henson]
|
|
|
|
*) New function X509_CRL_match() to check if two CRLs are identical. Normally
|
|
this would be called X509_CRL_cmp() but that name is already used by
|
|
a function that just compares CRL issuer names. Cache several CRL
|
|
extensions in X509_CRL structure and cache CRLDP in X509.
|
|
[Steve Henson]
|
|
|
|
*) Store a "canonical" representation of X509_NAME structure (ASN1 Name)
|
|
this maps equivalent X509_NAME structures into a consistent structure.
|
|
Name comparison can then be performed rapidly using memcmp().
|
|
[Steve Henson]
|
|
|
|
*) Non-blocking OCSP request processing. Add -timeout option to ocsp
|
|
utility.
|
|
[Steve Henson]
|
|
|
|
*) Allow digests to supply their own micalg string for S/MIME type using
|
|
the ctrl EVP_MD_CTRL_MICALG.
|
|
[Steve Henson]
|
|
|
|
*) During PKCS7 signing pass the PKCS7 SignerInfo structure to the
|
|
EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN
|
|
ctrl. It can then customise the structure before and/or after signing
|
|
if necessary.
|
|
[Steve Henson]
|
|
|
|
*) New function OBJ_add_sigid() to allow application defined signature OIDs
|
|
to be added to OpenSSLs internal tables. New function OBJ_sigid_free()
|
|
to free up any added signature OIDs.
|
|
[Steve Henson]
|
|
|
|
*) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(),
|
|
EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal
|
|
digest and cipher tables. New options added to openssl utility:
|
|
list-message-digest-algorithms and list-cipher-algorithms.
|
|
[Steve Henson]
|
|
|
|
*) Change the array representation of binary polynomials: the list
|
|
of degrees of non-zero coefficients is now terminated with -1.
|
|
Previously it was terminated with 0, which was also part of the
|
|
value; thus, the array representation was not applicable to
|
|
polynomials where t^0 has coefficient zero. This change makes
|
|
the array representation useful in a more general context.
|
|
[Douglas Stebila]
|
|
|
|
*) Various modifications and fixes to SSL/TLS cipher string
|
|
handling. For ECC, the code now distinguishes between fixed ECDH
|
|
with RSA certificates on the one hand and with ECDSA certificates
|
|
on the other hand, since these are separate ciphersuites. The
|
|
unused code for Fortezza ciphersuites has been removed.
|
|
|
|
For consistency with EDH, ephemeral ECDH is now called "EECDH"
|
|
(not "ECDHE"). For consistency with the code for DH
|
|
certificates, use of ECDH certificates is now considered ECDH
|
|
authentication, not RSA or ECDSA authentication (the latter is
|
|
merely the CA's signing algorithm and not actively used in the
|
|
protocol).
|
|
|
|
The temporary ciphersuite alias "ECCdraft" is no longer
|
|
available, and ECC ciphersuites are no longer excluded from "ALL"
|
|
and "DEFAULT". The following aliases now exist for RFC 4492
|
|
ciphersuites, most of these by analogy with the DH case:
|
|
|
|
kECDHr - ECDH cert, signed with RSA
|
|
kECDHe - ECDH cert, signed with ECDSA
|
|
kECDH - ECDH cert (signed with either RSA or ECDSA)
|
|
kEECDH - ephemeral ECDH
|
|
ECDH - ECDH cert or ephemeral ECDH
|
|
|
|
aECDH - ECDH cert
|
|
aECDSA - ECDSA cert
|
|
ECDSA - ECDSA cert
|
|
|
|
AECDH - anonymous ECDH
|
|
EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH")
|
|
|
|
[Bodo Moeller]
|
|
|
|
*) Add additional S/MIME capabilities for AES and GOST ciphers if supported.
|
|
Use correct micalg parameters depending on digest(s) in signed message.
|
|
[Steve Henson]
|
|
|
|
*) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process
|
|
an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code.
|
|
[Steve Henson]
|
|
|
|
*) Initial engine support for EVP_PKEY_METHOD. New functions to permit
|
|
an engine to register a method. Add ENGINE lookups for methods and
|
|
functional reference processing.
|
|
[Steve Henson]
|
|
|
|
*) New functions EVP_Digest{Sign,Verify)*. These are enhanced versions of
|
|
EVP_{Sign,Verify}* which allow an application to customise the signature
|
|
process.
|
|
[Steve Henson]
|
|
|
|
*) New -resign option to smime utility. This adds one or more signers
|
|
to an existing PKCS#7 signedData structure. Also -md option to use an
|
|
alternative message digest algorithm for signing.
|
|
[Steve Henson]
|
|
|
|
*) Tidy up PKCS#7 routines and add new functions to make it easier to
|
|
create PKCS7 structures containing multiple signers. Update smime
|
|
application to support multiple signers.
|
|
[Steve Henson]
|
|
|
|
*) New -macalg option to pkcs12 utility to allow setting of an alternative
|
|
digest MAC.
|
|
[Steve Henson]
|
|
|
|
*) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC.
|
|
Reorganize PBE internals to lookup from a static table using NIDs,
|
|
add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl:
|
|
EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative
|
|
PRF which will be automatically used with PBES2.
|
|
[Steve Henson]
|
|
|
|
*) Replace the algorithm specific calls to generate keys in "req" with the
|
|
new API.
|
|
[Steve Henson]
|
|
|
|
*) Update PKCS#7 enveloped data routines to use new API. This is now
|
|
supported by any public key method supporting the encrypt operation. A
|
|
ctrl is added to allow the public key algorithm to examine or modify
|
|
the PKCS#7 RecipientInfo structure if it needs to: for RSA this is
|
|
a no op.
|
|
[Steve Henson]
|
|
|
|
*) Add a ctrl to asn1 method to allow a public key algorithm to express
|
|
a default digest type to use. In most cases this will be SHA1 but some
|
|
algorithms (such as GOST) need to specify an alternative digest. The
|
|
return value indicates how strong the preference is 1 means optional and
|
|
2 is mandatory (that is it is the only supported type). Modify
|
|
ASN1_item_sign() to accept a NULL digest argument to indicate it should
|
|
use the default md. Update openssl utilities to use the default digest
|
|
type for signing if it is not explicitly indicated.
|
|
[Steve Henson]
|
|
|
|
*) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New
|
|
EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant
|
|
signing method from the key type. This effectively removes the link
|
|
between digests and public key types.
|
|
[Steve Henson]
|
|
|
|
*) Add an OID cross reference table and utility functions. Its purpose is to
|
|
translate between signature OIDs such as SHA1WithrsaEncryption and SHA1,
|
|
rsaEncryption. This will allow some of the algorithm specific hackery
|
|
needed to use the correct OID to be removed.
|
|
[Steve Henson]
|
|
|
|
*) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO
|
|
structures for PKCS7_sign(). They are now set up by the relevant public
|
|
key ASN1 method.
|
|
[Steve Henson]
|
|
|
|
*) Add provisional EC pkey method with support for ECDSA and ECDH.
|
|
[Steve Henson]
|
|
|
|
*) Add support for key derivation (agreement) in the API, DH method and
|
|
pkeyutl.
|
|
[Steve Henson]
|
|
|
|
*) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support
|
|
public and private key formats. As a side effect these add additional
|
|
command line functionality not previously available: DSA signatures can be
|
|
generated and verified using pkeyutl and DH key support and generation in
|
|
pkey, genpkey.
|
|
[Steve Henson]
|
|
|
|
*) BeOS support.
|
|
[Oliver Tappe <zooey@hirschkaefer.de>]
|
|
|
|
*) New make target "install_html_docs" installs HTML renditions of the
|
|
manual pages.
|
|
[Oliver Tappe <zooey@hirschkaefer.de>]
|
|
|
|
*) New utility "genpkey" this is analogous to "genrsa" etc except it can
|
|
generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to
|
|
support key and parameter generation and add initial key generation
|
|
functionality for RSA.
|
|
[Steve Henson]
|
|
|
|
*) Add functions for main EVP_PKEY_method operations. The undocumented
|
|
functions EVP_PKEY_{encrypt,decrypt} have been renamed to
|
|
EVP_PKEY_{encrypt,decrypt}_old.
|
|
[Steve Henson]
|
|
|
|
*) Initial definitions for EVP_PKEY_METHOD. This will be a high level public
|
|
key API, doesn't do much yet.
|
|
[Steve Henson]
|
|
|
|
*) New function EVP_PKEY_asn1_get0_info() to retrieve information about
|
|
public key algorithms. New option to openssl utility:
|
|
"list-public-key-algorithms" to print out info.
|
|
[Steve Henson]
|
|
|
|
*) Implement the Supported Elliptic Curves Extension for
|
|
ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
|
|
[Douglas Stebila]
|
|
|
|
*) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or
|
|
EVP_CIPHER structures to avoid later problems in EVP_cleanup().
|
|
[Steve Henson]
|
|
|
|
*) New utilities pkey and pkeyparam. These are similar to algorithm specific
|
|
utilities such as rsa, dsa, dsaparam etc except they process any key
|
|
type.
|
|
[Steve Henson]
|
|
|
|
*) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New
|
|
functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
|
|
EVP_PKEY_print_param() to print public key data from an EVP_PKEY
|
|
structure.
|
|
[Steve Henson]
|
|
|
|
*) Initial support for pluggable public key ASN1.
|
|
De-spaghettify the public key ASN1 handling. Move public and private
|
|
key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate
|
|
algorithm specific handling to a single module within the relevant
|
|
algorithm directory. Add functions to allow (near) opaque processing
|
|
of public and private key structures.
|
|
[Steve Henson]
|
|
|
|
*) Implement the Supported Point Formats Extension for
|
|
ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
|
|
[Douglas Stebila]
|
|
|
|
*) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members
|
|
for the psk identity [hint] and the psk callback functions to the
|
|
SSL_SESSION, SSL and SSL_CTX structure.
|
|
|
|
New ciphersuites:
|
|
PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA,
|
|
PSK-AES256-CBC-SHA
|
|
|
|
New functions:
|
|
SSL_CTX_use_psk_identity_hint
|
|
SSL_get_psk_identity_hint
|
|
SSL_get_psk_identity
|
|
SSL_use_psk_identity_hint
|
|
|
|
[Mika Kousa and Pasi Eronen of Nokia Corporation]
|
|
|
|
*) Add RFC 3161 compliant time stamp request creation, response generation
|
|
and response verification functionality.
|
|
[Zoltán Glózik <zglozik@opentsa.org>, The OpenTSA Project]
|
|
|
|
*) Add initial support for TLS extensions, specifically for the server_name
|
|
extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now
|
|
have new members for a host name. The SSL data structure has an
|
|
additional member SSL_CTX *initial_ctx so that new sessions can be
|
|
stored in that context to allow for session resumption, even after the
|
|
SSL has been switched to a new SSL_CTX in reaction to a client's
|
|
server_name extension.
|
|
|
|
New functions (subject to change):
|
|
|
|
SSL_get_servername()
|
|
SSL_get_servername_type()
|
|
SSL_set_SSL_CTX()
|
|
|
|
New CTRL codes and macros (subject to change):
|
|
|
|
SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
|
|
- SSL_CTX_set_tlsext_servername_callback()
|
|
SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG
|
|
- SSL_CTX_set_tlsext_servername_arg()
|
|
SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name()
|
|
|
|
openssl s_client has a new '-servername ...' option.
|
|
|
|
openssl s_server has new options '-servername_host ...', '-cert2 ...',
|
|
'-key2 ...', '-servername_fatal' (subject to change). This allows
|
|
testing the HostName extension for a specific single host name ('-cert'
|
|
and '-key' remain fallbacks for handshakes without HostName
|
|
negotiation). If the unrecognized_name alert has to be sent, this by
|
|
default is a warning; it becomes fatal with the '-servername_fatal'
|
|
option.
|
|
|
|
[Peter Sylvester, Remy Allais, Christophe Renou]
|
|
|
|
*) Whirlpool hash implementation is added.
|
|
[Andy Polyakov]
|
|
|
|
*) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to
|
|
bn(64,32). Because of instruction set limitations it doesn't have
|
|
any negative impact on performance. This was done mostly in order
|
|
to make it possible to share assembler modules, such as bn_mul_mont
|
|
implementations, between 32- and 64-bit builds without hassle.
|
|
[Andy Polyakov]
|
|
|
|
*) Move code previously exiled into file crypto/ec/ec2_smpt.c
|
|
to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP
|
|
macro.
|
|
[Bodo Moeller]
|
|
|
|
*) New candidate for BIGNUM assembler implementation, bn_mul_mont,
|
|
dedicated Montgomery multiplication procedure, is introduced.
|
|
BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher
|
|
"64-bit" performance on certain 32-bit targets.
|
|
[Andy Polyakov]
|
|
|
|
*) New option SSL_OP_NO_COMP to disable use of compression selectively
|
|
in SSL structures. New SSL ctrl to set maximum send fragment size.
|
|
Save memory by setting the I/O buffer sizes dynamically instead of
|
|
using the maximum available value.
|
|
[Steve Henson]
|
|
|
|
*) New option -V for 'openssl ciphers'. This prints the ciphersuite code
|
|
in addition to the text details.
|
|
[Bodo Moeller]
|
|
|
|
*) Very, very preliminary EXPERIMENTAL support for printing of general
|
|
ASN1 structures. This currently produces rather ugly output and doesn't
|
|
handle several customised structures at all.
|
|
[Steve Henson]
|
|
|
|
*) Integrated support for PVK file format and some related formats such
|
|
as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
|
|
these in the 'rsa' and 'dsa' utilities.
|
|
[Steve Henson]
|
|
|
|
*) Support for PKCS#1 RSAPublicKey format on rsa utility command line.
|
|
[Steve Henson]
|
|
|
|
*) Remove the ancient ASN1_METHOD code. This was only ever used in one
|
|
place for the (very old) "NETSCAPE" format certificates which are now
|
|
handled using new ASN1 code equivalents.
|
|
[Steve Henson]
|
|
|
|
*) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD
|
|
pointer and make the SSL_METHOD parameter in SSL_CTX_new,
|
|
SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'.
|
|
[Nils Larsch]
|
|
|
|
*) Modify CRL distribution points extension code to print out previously
|
|
unsupported fields. Enhance extension setting code to allow setting of
|
|
all fields.
|
|
[Steve Henson]
|
|
|
|
*) Add print and set support for Issuing Distribution Point CRL extension.
|
|
[Steve Henson]
|
|
|
|
*) Change 'Configure' script to enable Camellia by default.
|
|
[NTT]
|
|
|
|
Changes between 0.9.8m and 0.9.8n [24 Mar 2010]
|
|
|
|
*) When rejecting SSL/TLS records due to an incorrect version number, never
|
|
update s->server with a new major version number. As of
|
|
- OpenSSL 0.9.8m if 'short' is a 16-bit type,
|
|
- OpenSSL 0.9.8f if 'short' is longer than 16 bits,
|
|
the previous behavior could result in a read attempt at NULL when
|
|
receiving specific incorrect SSL/TLS records once record payload
|
|
protection is active. (CVE-2010-0740)
|
|
[Bodo Moeller, Adam Langley <agl@chromium.org>]
|
|
|
|
*) Fix for CVE-2010-0433 where some kerberos enabled versions of OpenSSL
|
|
could be crashed if the relevant tables were not present (e.g. chrooted).
|
|
[Tomas Hoger <thoger@redhat.com>]
|
|
|
|
Changes between 0.9.8l and 0.9.8m [25 Feb 2010]
|
|
|
|
*) Always check bn_wexpand() return values for failure. (CVE-2009-3245)
|
|
[Martin Olsson, Neel Mehta]
|
|
|
|
*) Fix X509_STORE locking: Every 'objs' access requires a lock (to
|
|
accommodate for stack sorting, always a write lock!).
|
|
[Bodo Moeller]
|
|
|
|
*) On some versions of WIN32 Heap32Next is very slow. This can cause
|
|
excessive delays in the RAND_poll(): over a minute. As a workaround
|
|
include a time check in the inner Heap32Next loop too.
|
|
[Steve Henson]
|
|
|
|
*) The code that handled flushing of data in SSL/TLS originally used the
|
|
BIO_CTRL_INFO ctrl to see if any data was pending first. This caused
|
|
the problem outlined in PR#1949. The fix suggested there however can
|
|
trigger problems with buggy BIO_CTRL_WPENDING (e.g. some versions
|
|
of Apache). So instead simplify the code to flush unconditionally.
|
|
This should be fine since flushing with no data to flush is a no op.
|
|
[Steve Henson]
|
|
|
|
*) Handle TLS versions 2.0 and later properly and correctly use the
|
|
highest version of TLS/SSL supported. Although TLS >= 2.0 is some way
|
|
off ancient servers have a habit of sticking around for a while...
|
|
[Steve Henson]
|
|
|
|
*) Modify compression code so it frees up structures without using the
|
|
ex_data callbacks. This works around a problem where some applications
|
|
call CRYPTO_cleanup_all_ex_data() before application exit (e.g. when
|
|
restarting) then use compression (e.g. SSL with compression) later.
|
|
This results in significant per-connection memory leaks and
|
|
has caused some security issues including CVE-2008-1678 and
|
|
CVE-2009-4355.
|
|
[Steve Henson]
|
|
|
|
*) Constify crypto/cast (i.e., <openssl/cast.h>): a CAST_KEY doesn't
|
|
change when encrypting or decrypting.
|
|
[Bodo Moeller]
|
|
|
|
*) Add option SSL_OP_LEGACY_SERVER_CONNECT which will allow clients to
|
|
connect and renegotiate with servers which do not support RI.
|
|
Until RI is more widely deployed this option is enabled by default.
|
|
[Steve Henson]
|
|
|
|
*) Add "missing" ssl ctrls to clear options and mode.
|
|
[Steve Henson]
|
|
|
|
*) If client attempts to renegotiate and doesn't support RI respond with
|
|
a no_renegotiation alert as required by RFC5746. Some renegotiating
|
|
TLS clients will continue a connection gracefully when they receive
|
|
the alert. Unfortunately OpenSSL mishandled this alert and would hang
|
|
waiting for a server hello which it will never receive. Now we treat a
|
|
received no_renegotiation alert as a fatal error. This is because
|
|
applications requesting a renegotiation might well expect it to succeed
|
|
and would have no code in place to handle the server denying it so the
|
|
only safe thing to do is to terminate the connection.
|
|
[Steve Henson]
|
|
|
|
*) Add ctrl macro SSL_get_secure_renegotiation_support() which returns 1 if
|
|
peer supports secure renegotiation and 0 otherwise. Print out peer
|
|
renegotiation support in s_client/s_server.
|
|
[Steve Henson]
|
|
|
|
*) Replace the highly broken and deprecated SPKAC certification method with
|
|
the updated NID creation version. This should correctly handle UTF8.
|
|
[Steve Henson]
|
|
|
|
*) Implement RFC5746. Re-enable renegotiation but require the extension
|
|
as needed. Unfortunately, SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION
|
|
turns out to be a bad idea. It has been replaced by
|
|
SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION which can be set with
|
|
SSL_CTX_set_options(). This is really not recommended unless you
|
|
know what you are doing.
|
|
[Eric Rescorla <ekr@networkresonance.com>, Ben Laurie, Steve Henson]
|
|
|
|
*) Fixes to stateless session resumption handling. Use initial_ctx when
|
|
issuing and attempting to decrypt tickets in case it has changed during
|
|
servername handling. Use a non-zero length session ID when attempting
|
|
stateless session resumption: this makes it possible to determine if
|
|
a resumption has occurred immediately after receiving server hello
|
|
(several places in OpenSSL subtly assume this) instead of later in
|
|
the handshake.
|
|
[Steve Henson]
|
|
|
|
*) The functions ENGINE_ctrl(), OPENSSL_isservice(),
|
|
CMS_get1_RecipientRequest() and RAND_bytes() can return <=0 on error
|
|
fixes for a few places where the return code is not checked
|
|
correctly.
|
|
[Julia Lawall <julia@diku.dk>]
|
|
|
|
*) Add --strict-warnings option to Configure script to include devteam
|
|
warnings in other configurations.
|
|
[Steve Henson]
|
|
|
|
*) Add support for --libdir option and LIBDIR variable in makefiles. This
|
|
makes it possible to install openssl libraries in locations which
|
|
have names other than "lib", for example "/usr/lib64" which some
|
|
systems need.
|
|
[Steve Henson, based on patch from Jeremy Utley]
|
|
|
|
*) Don't allow the use of leading 0x80 in OIDs. This is a violation of
|
|
X690 8.9.12 and can produce some misleading textual output of OIDs.
|
|
[Steve Henson, reported by Dan Kaminsky]
|
|
|
|
*) Delete MD2 from algorithm tables. This follows the recommendation in
|
|
several standards that it is not used in new applications due to
|
|
several cryptographic weaknesses. For binary compatibility reasons
|
|
the MD2 API is still compiled in by default.
|
|
[Steve Henson]
|
|
|
|
*) Add compression id to {d2i,i2d}_SSL_SESSION so it is correctly saved
|
|
and restored.
|
|
[Steve Henson]
|
|
|
|
*) Rename uni2asc and asc2uni functions to OPENSSL_uni2asc and
|
|
OPENSSL_asc2uni conditionally on Netware platforms to avoid a name
|
|
clash.
|
|
[Guenter <lists@gknw.net>]
|
|
|
|
*) Fix the server certificate chain building code to use X509_verify_cert(),
|
|
it used to have an ad-hoc builder which was unable to cope with anything
|
|
other than a simple chain.
|
|
[David Woodhouse <dwmw2@infradead.org>, Steve Henson]
|
|
|
|
*) Don't check self signed certificate signatures in X509_verify_cert()
|
|
by default (a flag can override this): it just wastes time without
|
|
adding any security. As a useful side effect self signed root CAs
|
|
with non-FIPS digests are now usable in FIPS mode.
|
|
[Steve Henson]
|
|
|
|
*) In dtls1_process_out_of_seq_message() the check if the current message
|
|
is already buffered was missing. For every new message was memory
|
|
allocated, allowing an attacker to perform an denial of service attack
|
|
with sending out of seq handshake messages until there is no memory
|
|
left. Additionally every future message was buffered, even if the
|
|
sequence number made no sense and would be part of another handshake.
|
|
So only messages with sequence numbers less than 10 in advance will be
|
|
buffered. (CVE-2009-1378)
|
|
[Robin Seggelmann, discovered by Daniel Mentz]
|
|
|
|
*) Records are buffered if they arrive with a future epoch to be
|
|
processed after finishing the corresponding handshake. There is
|
|
currently no limitation to this buffer allowing an attacker to perform
|
|
a DOS attack with sending records with future epochs until there is no
|
|
memory left. This patch adds the pqueue_size() function to determine
|
|
the size of a buffer and limits the record buffer to 100 entries.
|
|
(CVE-2009-1377)
|
|
[Robin Seggelmann, discovered by Daniel Mentz]
|
|
|
|
*) Keep a copy of frag->msg_header.frag_len so it can be used after the
|
|
parent structure is freed. (CVE-2009-1379)
|
|
[Daniel Mentz]
|
|
|
|
*) Handle non-blocking I/O properly in SSL_shutdown() call.
|
|
[Darryl Miles <darryl-mailinglists@netbauds.net>]
|
|
|

[Ilya O. <vrghost@gmail.com>]
|
|
|
|
Changes between 0.9.8k and 0.9.8l [5 Nov 2009]
|
|
|
|
*) Disable renegotiation completely - this fixes a severe security
|
|
problem (CVE-2009-3555) at the cost of breaking all
|
|
renegotiation. Renegotiation can be re-enabled by setting
|
|
SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION in s3->flags at
|
|
run-time. This is really not recommended unless you know what
|
|
you're doing.
|
|
[Ben Laurie]
|
|
|
|
Changes between 0.9.8j and 0.9.8k [25 Mar 2009]
|
|
|
|
*) Don't set val to NULL when freeing up structures, it is freed up by
|
|
underlying code. If sizeof(void *) > sizeof(long) this can result in
|
|
zeroing past the valid field. (CVE-2009-0789)
|
|
[Paolo Ganci <Paolo.Ganci@AdNovum.CH>]
|
|
|
|
*) Fix bug where return value of CMS_SignerInfo_verify_content() was not
|
|
checked correctly. This would allow some invalid signed attributes to
|
|
appear to verify correctly. (CVE-2009-0591)
|
|
[Ivan Nestlerode <inestlerode@us.ibm.com>]
|
|
|
|
*) Reject UniversalString and BMPString types with invalid lengths. This
|
|
prevents a crash in ASN1_STRING_print_ex() which assumes the strings have
|
|
a legal length. (CVE-2009-0590)
|
|
[Steve Henson]
|
|
|
|
*) Set S/MIME signing as the default purpose rather than setting it
|
|
unconditionally. This allows applications to override it at the store
|
|
level.
|
|
[Steve Henson]
|
|
|
|
*) Permit restricted recursion of ASN1 strings. This is needed in practice
|
|
to handle some structures.
|
|
[Steve Henson]
|
|
|
|
*) Improve efficiency of mem_gets: don't search whole buffer each time
|
|
for a '\n'
|
|
[Jeremy Shapiro <jnshapir@us.ibm.com>]
|
|
|
|
*) New -hex option for openssl rand.
|
|
[Matthieu Herrb]
|
|
|
|
*) Print out UTF8String and NumericString when parsing ASN1.
|
|
[Steve Henson]
|
|
|
|
*) Support NumericString type for name components.
|
|
[Steve Henson]
|
|
|
|
*) Allow CC in the environment to override the automatically chosen
|
|
compiler. Note that nothing is done to ensure flags work with the
|
|
chosen compiler.

[Ben Laurie]
|
|
|

Changes between 0.9.8i and 0.9.8j [07 Jan 2009]
|
|
|
|
*) Properly check EVP_VerifyFinal() and similar return values
|
|
(CVE-2008-5077).
|
|
[Ben Laurie, Bodo Moeller, Google Security Team]
|
|
|
|
*) Enable TLS extensions by default.
|
|
[Ben Laurie]
|
|
|
|
*) Allow the CHIL engine to be loaded, whether the application is
|
|
multithreaded or not. (This does not release the developer from the
|
|
obligation to set up the dynamic locking callbacks.)
|
|
[Sander Temme <sander@temme.net>]
|
|
|
|
*) Use correct exit code if there is an error in dgst command.
|
|
[Steve Henson; problem pointed out by Roland Dirlewanger]
|
|
|
|
*) Tweak Configure so that you need to say "experimental-jpake" to enable
|
|
JPAKE, and need to use -DOPENSSL_EXPERIMENTAL_JPAKE in applications.
|
|
[Bodo Moeller]
|
|
|
|
*) Add experimental JPAKE support, including demo authentication in
|
|
s_client and s_server.
|
|
[Ben Laurie]
|
|
|
|
*) Set the comparison function in v3_addr_canonize().
|
|
[Rob Austein <sra@hactrn.net>]
|
|
|
|
*) Add support for XMPP STARTTLS in s_client.
|
|
[Philip Paeps <philip@freebsd.org>]
|
|
|
|
*) Change the server-side SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG behavior
|
|
to ensure that even with this option, only ciphersuites in the
|
|
server's preference list will be accepted. (Note that the option
|
|
applies only when resuming a session, so the earlier behavior was
|
|
just about the algorithm choice for symmetric cryptography.)

[Bodo Moeller]
|
|
|
|
Changes between 0.9.8h and 0.9.8i [15 Sep 2008]
|
|
|
|
*) Fix NULL pointer dereference if a DTLS server received
|
|
ChangeCipherSpec as first record (CVE-2009-1386).
|
|
[PR #1679]
|
|
|
|
*) Fix a state transition in s3_srvr.c and d1_srvr.c
|
|
(was using SSL3_ST_CW_CLNT_HELLO_B, should be ..._ST_SW_SRVR_...).
|
|
[Nagendra Modadugu]
|
|
|
|
*) The fix in 0.9.8c that supposedly got rid of unsafe
|
|
double-checked locking was incomplete for RSA blinding,
|
|
addressing just one layer of what turns out to have been
|
|
doubly unsafe triple-checked locking.
|
|
|
|
So now fix this for real by retiring the MONT_HELPER macro
|
|
in crypto/rsa/rsa_eay.c.
|
|
|
|
[Bodo Moeller; problem pointed out by Marius Schilder]
|
|
|
|
*) Various precautionary measures:
|
|
|
|
- Avoid size_t integer overflow in HASH_UPDATE (md32_common.h).
|
|
|
|
- Avoid a buffer overflow in d2i_SSL_SESSION() (ssl_asn1.c).
|
|
(NB: This would require knowledge of the secret session ticket key
|
|
to exploit, in which case you'd be SOL either way.)
|
|
|
|
- Change bn_nist.c so that it will properly handle input BIGNUMs
|
|
outside the expected range.
|
|
|
|
- Enforce the 'num' check in BN_div() (bn_div.c) for non-BN_DEBUG
|
|
builds.

*) Allow engines to be "soft loaded" - i.e. optionally don't die if
|
|
the load fails. Useful for distros.

[Steve Henson]
|
|
|
|
*) Add CryptoAPI ENGINE to support use of RSA and DSA keys held in Windows

[Steve Henson]
|
|
|
|
*) Fix bug in X509_ATTRIBUTE creation: don't set attribute using
|
|
ASN1_TYPE_set1 if MBSTRING flag set. This bug would crash certain
|
|
attribute creation routines such as certificate requests and PKCS#12

Changes between 0.9.8g and 0.9.8h [28 May 2008]
|
|
|
|
*) Fix flaw if 'Server Key exchange message' is omitted from a TLS
|
|
handshake which could lead to a client crash as found using the
|
|
Codenomicon TLS test suite (CVE-2008-1672)
|
|
[Steve Henson, Mark Cox]
|

[Joe Orton]
|
|
|
|
*) Clear error queue in SSL_CTX_use_certificate_chain_file()
|
|
|
|
Clear the error queue to ensure that error entries left from
|
|
older function calls do not interfere with the correct operation.
|
|
[Lutz Jaenicke, Erik de Castro Lopo]
|
|
|
|
*) Remove root CA certificates of commercial CAs:
|
|
|
|
The OpenSSL project does not recommend any specific CA and does not
|
|
have any policy with respect to including or excluding any CA.
|
|
Therefore it does not make any sense to ship an arbitrary selection
|
|
of root CA certificates with the OpenSSL software.
|
|
[Lutz Jaenicke]
|
|
|
|
*) RSA OAEP patches to fix two separate invalid memory reads.
|
|
The first one involves inputs when 'lzero' is greater than
|
|
'SHA_DIGEST_LENGTH' (it would read about SHA_DIGEST_LENGTH bytes
|
|
before the beginning of from). The second one involves inputs where
|
|
the 'db' section contains nothing but zeroes (there is a one-byte
|
|
invalid read after the end of 'db').
|
|
[Ivan Nestlerode <inestlerode@us.ibm.com>]
|
|
|
|
*) Partial backport from 0.9.9-dev:
|
|
|
|
Introduce bn_mul_mont (dedicated Montgomery multiplication
|
|
procedure) as a candidate for BIGNUM assembler implementation.
|
|
While 0.9.9-dev uses assembler for various architectures, only
|
|
x86_64 is available by default here in the 0.9.8 branch, and
|
|
32-bit x86 is available through a compile-time setting.
|
|
|
|
To try the 32-bit x86 assembler implementation, use Configure
|
|
option "enable-montasm" (which exists only for this backport).
|
|
|
|
As "enable-montasm" for 32-bit x86 disclaims code stability
|
|
anyway, in this constellation we activate additional code
|
|
backported from 0.9.9-dev for further performance improvements,
|
|
namely BN_from_montgomery_word. (To enable this otherwise,
|
|
e.g. x86_64, try "-DMONT_FROM_WORD___NON_DEFAULT_0_9_8_BUILD".)
|
|
|
|
[Andy Polyakov (backport partially by Bodo Moeller)]
|
|
|
|
*) Add TLS session ticket callback. This allows an application to set
|
|
TLS ticket cipher and HMAC keys rather than relying on hardcoded fixed
|
|
values. This is useful for key rollover for example where several key
|
|
sets may exist with different names.
|
|
[Steve Henson]
|
|
|
|
*) Reverse ENGINE-internal logic for caching default ENGINE handles.
|
|
This was broken until now in 0.9.8 releases, such that the only way
|
|
a registered ENGINE could be used (assuming it initialises
|
|
successfully on the host) was to explicitly set it as the default
|
|
for the relevant algorithms. This is in contradiction with 0.9.7
|
|
behaviour and the documentation. With this fix, when an ENGINE is
|
|
registered into a given algorithm's table of implementations, the
|
|
'uptodate' flag is reset so that auto-discovery will be used next
|
|
time a new context for that algorithm attempts to select an
|
|
implementation.
|
|
[Ian Lister (tweaked by Geoff Thorpe)]
|
|
|
|
*) Backport of CMS code to OpenSSL 0.9.8. This differs from the 0.9.9
|
|
implementation in the following ways:
|
|
|
|
Lack of EVP_PKEY_ASN1_METHOD means algorithm parameters have to be
|
|
hard coded.
|
|
|
|
Lack of BER streaming support means one pass streaming processing is
|
|
only supported if data is detached: setting the streaming flag is
|
|
ignored for embedded content.
|
|
|
|
CMS support is disabled by default and must be explicitly enabled
|
|
with the enable-cms configuration option.
|
|
[Steve Henson]
|
|
|
|
*) Update the GMP engine glue to do direct copies between BIGNUM and
|
|
mpz_t when openssl and GMP use the same limb size. Otherwise the
|
|
existing "conversion via a text string export" trick is still used.
|
|
[Paul Sheer <paulsheer@gmail.com>]
|
|
|
|
*) Zlib compression BIO. This is a filter BIO which compressed and
|
|
uncompresses any data passed through it.
|
|
[Steve Henson]
|
|
|
|
*) Add AES_wrap_key() and AES_unwrap_key() functions to implement
|
|
RFC3394 compatible AES key wrapping.
|
|
[Steve Henson]
|
|
|
|
*) Add utility functions to handle ASN1 structures. ASN1_STRING_set0():
|
|
sets string data without copying. X509_ALGOR_set0() and
|
|
X509_ALGOR_get0(): set and retrieve X509_ALGOR (AlgorithmIdentifier)
|
|
data. Attribute function X509at_get0_data_by_OBJ(): retrieves data
|
|
from an X509_ATTRIBUTE structure optionally checking it occurs only
|
|
once. ASN1_TYPE_set1(): set and ASN1_TYPE structure copying supplied
|
|
data.
|
|
[Steve Henson]
|
|
|
|
*) Fix BN flag handling in RSA_eay_mod_exp() and BN_MONT_CTX_set()
|
|
to get the expected BN_FLG_CONSTTIME behavior.
|
|
[Bodo Moeller (Google)]
|
|
|
|
*) Netware support:
|
|
|
|
- fixed wrong usage of ioctlsocket() when build for LIBC BSD sockets
|
|
- fixed do_tests.pl to run the test suite with CLIB builds too (CLIB_OPT)
|
|
- added some more tests to do_tests.pl
|
|
- fixed RunningProcess usage so that it works with newer LIBC NDKs too
|
|
- removed usage of BN_LLONG for CLIB builds to avoid runtime dependency
|
|
- added new Configure targets netware-clib-bsdsock, netware-clib-gcc,
|
|
netware-clib-bsdsock-gcc, netware-libc-bsdsock-gcc
|
|
- various changes to netware.pl to enable gcc-cross builds on Win32
|
|
platform
|
|
- changed crypto/bio/b_sock.c to work with macro functions (CLIB BSD)
|
|
- various changes to fix missing prototype warnings
|
|
- fixed x86nasm.pl to create correct asm files for NASM COFF output
|
|
- added AES, WHIRLPOOL and CPUID assembler code to build files
|
|
- added missing AES assembler make rules to mk1mf.pl
|
|
- fixed order of includes in apps/ocsp.c so that e_os.h settings apply
|

[Guenter Knauf <eflash@gmx.net>]
|
|
|
|
*) Implement certificate status request TLS extension defined in RFC3546.
|
|
A client can set the appropriate parameters and receive the encoded
|

|
+ Binary incompatibility of ssl_ctx_st structure

|
[Andy Polyakov, Steve Henson]
|
|
|
|
Changes between 0.9.8e and 0.9.8f [11 Oct 2007]
|
|
|
|
*) DTLS Handshake overhaul. There were longstanding issues with
|
|
OpenSSL DTLS implementation, which were making it impossible for
|
|
RFC 4347 compliant client to communicate with OpenSSL server.
|
|
Unfortunately just fixing these incompatibilities would "cut off"
|
|
pre-0.9.8f clients. To allow for hassle free upgrade post-0.9.8e
|
|
server keeps tolerating non RFC compliant syntax. The opposite is
|
|
not true, 0.9.8f client can not communicate with earlier server.
|
|
This update even addresses CVE-2007-4995.
|
|
[Andy Polyakov]
|
|
|
|
*) Changes to avoid need for function casts in OpenSSL: some compilers
|
|
(gcc 4.2 and later) reject their use.
|
|
[Kurt Roeckx <kurt@roeckx.be>, Peter Hartley <pdh@utter.chaos.org.uk>,
|
|
Steve Henson]
|
|
|
|
*) Add RFC4507 support to OpenSSL. This includes the corrections in
|
|
RFC4507bis. The encrypted ticket format is an encrypted encoded
|
|
SSL_SESSION structure, that way new session features are automatically
|
|
supported.
|
|
|
|
If a client application caches session in an SSL_SESSION structure
|
|
support is transparent because tickets are now stored in the encoded
|
|
SSL_SESSION.
|
|
|
|
The SSL_CTX structure automatically generates keys for ticket
|
|
protection in servers so again support should be possible
|
|
with no application modification.
|
|
|
|
If a client or server wishes to disable RFC4507 support then the option
|
|
SSL_OP_NO_TICKET can be set.
|
|
|
|
Add a TLS extension debugging callback to allow the contents of any client
|
|
or server extensions to be examined.
|
|
|
|
This work was sponsored by Google.
|
|
[Steve Henson]
|
|
|
|
*) Add initial support for TLS extensions, specifically for the server_name
|
|
extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now
|
|
have new members for a host name. The SSL data structure has an
|
|
additional member SSL_CTX *initial_ctx so that new sessions can be
|
|
stored in that context to allow for session resumption, even after the
|
|
SSL has been switched to a new SSL_CTX in reaction to a client's
|
|
server_name extension.
|
|
|
|
New functions (subject to change):
|
|
|
|
SSL_get_servername()
|
|
SSL_get_servername_type()
|
|
SSL_set_SSL_CTX()
|
|
|
|
New CTRL codes and macros (subject to change):
|
|
|
|
SSL_CTRL_SET_TLSEXT_SERVERNAME_CB
|
|
- SSL_CTX_set_tlsext_servername_callback()
|
|
SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG
|
|
- SSL_CTX_set_tlsext_servername_arg()
|
|
SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name()
|
|
|
|
openssl s_client has a new '-servername ...' option.
|
|
|
|
openssl s_server has new options '-servername_host ...', '-cert2 ...',
|
|
'-key2 ...', '-servername_fatal' (subject to change). This allows
|
|
testing the HostName extension for a specific single host name ('-cert'
|
|
and '-key' remain fallbacks for handshakes without HostName
|
|
negotiation). If the unrecognized_name alert has to be sent, this by
|
|
default is a warning; it becomes fatal with the '-servername_fatal'
|
|
option.
|
|

|
[Peter Sylvester, Remy Allais, Christophe Renou, Steve Henson]
|
|

|
[Ben Laurie]
|
|
|
|
*) AES IGE mode speedup.
|
|
[Dean Gaudet (Google)]
|
|
|
|
*) Add the Korean symmetric 128-bit cipher SEED (see
|
|
http://www.kisa.or.kr/kisa/seed/jsp/seed_eng.jsp) and
|
|
add SEED ciphersuites from RFC 4162:
|
|
|
|
TLS_RSA_WITH_SEED_CBC_SHA = "SEED-SHA"
|
|
TLS_DHE_DSS_WITH_SEED_CBC_SHA = "DHE-DSS-SEED-SHA"
|
|
TLS_DHE_RSA_WITH_SEED_CBC_SHA = "DHE-RSA-SEED-SHA"
|
|
TLS_DH_anon_WITH_SEED_CBC_SHA = "ADH-SEED-SHA"
|
|
|
|
To minimize changes between patchlevels in the OpenSSL 0.9.8
|
|
series, SEED remains excluded from compilation unless OpenSSL
|
|
is configured with 'enable-seed'.
|
|
[KISA, Bodo Moeller]
|
|
|
|
*) Mitigate branch prediction attacks, which can be practical if a
|
|
single processor is shared, allowing a spy process to extract
|
|
information. For detailed background information, see
|
|
http://eprint.iacr.org/2007/039 (O. Aciicmez, S. Gueron,
|
|
J.-P. Seifert, "New Branch Prediction Vulnerabilities in OpenSSL
|
|
and Necessary Software Countermeasures"). The core of the change
|
|
are new versions BN_div_no_branch() and
|
|
BN_mod_inverse_no_branch() of BN_div() and BN_mod_inverse(),
|
|
respectively, which are slower, but avoid the security-relevant
|
|
conditional branches. These are automatically called by BN_div()
|
|
and BN_mod_inverse() if the flag BN_FLG_CONSTTIME is set for one
|
|
of the input BIGNUMs. Also, BN_is_bit_set() has been changed to
|
|
remove a conditional branch.
|
|
|
|
BN_FLG_CONSTTIME is the new name for the previous
|
|
BN_FLG_EXP_CONSTTIME flag, since it now affects more than just
|
|
modular exponentiation. (Since OpenSSL 0.9.7h, setting this flag
|
|
in the exponent causes BN_mod_exp_mont() to use the alternative
|
|
implementation in BN_mod_exp_mont_consttime().) The old name
|
|
remains as a deprecated alias.
|
|
|
|
Similarly, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general
|
|
RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses
|
|
constant-time implementations for more than just exponentiation.
|
|
Here too the old name is kept as a deprecated alias.
|
|
|
|
BN_BLINDING_new() will now use BN_dup() for the modulus so that
|
|
the BN_BLINDING structure gets an independent copy of the
|
|
modulus. This means that the previous "BIGNUM *m" argument to
|
|
BN_BLINDING_new() and to BN_BLINDING_create_param() now
|
|
essentially becomes "const BIGNUM *m", although we can't actually
|
|
change this in the header file before 0.9.9. It allows
|
|
RSA_setup_blinding() to use BN_with_flags() on the modulus to
|
|
enable BN_FLG_CONSTTIME.
|
|
|
|
[Matthew D Wood (Intel Corp)]
|
|
|
|
*) In the SSL/TLS server implementation, be strict about session ID
|
|
context matching (which matters if an application uses a single
|
|
external cache for different purposes). Previously,
|
|
out-of-context reuse was forbidden only if SSL_VERIFY_PEER was
|
|
set. This did ensure strict client verification, but meant that,
|
|
with applications using a single external cache for quite
|
|
different requirements, clients could circumvent ciphersuite
|
|
restrictions for a given session ID context by starting a session
|
|
in a different context.
|
|
[Bodo Moeller]
|
|
|
|
*) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that
|
|
a ciphersuite string such as "DEFAULT:RSA" cannot enable
|
|
authentication-only ciphersuites.
|
|
[Bodo Moeller]

(CVE-2007-5135) [Ben Laurie]
|
|
|
|
Changes between 0.9.8d and 0.9.8e [23 Feb 2007]
|
|
|
|
*) Since AES128 and AES256 (and similarly Camellia128 and
|
|
Camellia256) share a single mask bit in the logic of
|
|
ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a
|
|
kludge to work properly if AES128 is available and AES256 isn't
|
|
(or if Camellia128 is available and Camellia256 isn't).
|
|
[Victor Duchovni]
|
|
|
|
*) Fix the BIT STRING encoding generated by crypto/ec/ec_asn1.c
|
|
(within i2d_ECPrivateKey, i2d_ECPKParameters, i2d_ECParameters):
|
|
When a point or a seed is encoded in a BIT STRING, we need to
|
|
prevent the removal of trailing zero bits to get the proper DER
|
|
encoding. (By default, crypto/asn1/a_bitstr.c assumes the case
|
|
of a NamedBitList, for which trailing 0 bits need to be removed.)
|
|
[Bodo Moeller]
|
|
|
|
*) Have SSL/TLS server implementation tolerate "mismatched" record
|
|
protocol version while receiving ClientHello even if the
|
|
ClientHello is fragmented. (The server can't insist on the
|
|
particular protocol version it has chosen before the ServerHello
|
|
message has informed the client about his choice.)

[Bodo Moeller]

|
malicious SSLv2 server. (CVE-2006-4343)
|
|
[Tavis Ormandy and Will Drewry, Google Security Team]
|
|
|
|
*) Since 0.9.8b, ciphersuite strings naming explicit ciphersuites
|
|
match only those. Before that, "AES256-SHA" would be interpreted
|
|
as a pattern and match "AES128-SHA" too (since AES128-SHA got
|
|
the same strength classification in 0.9.7h) as we currently only
|
|
have a single AES bit in the ciphersuite description bitmap.
|
|
That change, however, also applied to ciphersuite strings such as
|
|
"RC4-MD5" that intentionally matched multiple ciphersuites --
|
|
namely, SSL 2.0 ciphersuites in addition to the more common ones
|
|
from SSL 3.0/TLS 1.0.
|
|
|
|
So we change the selection algorithm again: Naming an explicit
|
|
ciphersuite selects this one ciphersuite, and any other similar
|
|
ciphersuite (same bitmap) from *other* protocol versions.
|
|
Thus, "RC4-MD5" again will properly select both the SSL 2.0
|
|
ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite.
|
|
|
|
Since SSL 2.0 does not have any ciphersuites for which the
|
|
128/256 bit distinction would be relevant, this works for now.
|
|
The proper fix will be to use different bits for AES128 and
|
|
AES256, which would have avoided the problems from the beginning;
|
|
however, bits are scarce, so we can only do this in a new release
|
|
(not just a patchlevel) when we can change the SSL_CIPHER
|
|
definition to split the single 'unsigned long mask' bitmap into
|
|
multiple values to extend the available space.

*) Add AES IGE and biIGE modes.

undesirable limitations.
|
|
[Darryl Miles via Richard Levitte and Bodo Moeller]
|
|
|
|
*) Disable "ECCdraft" ciphersuites more thoroughly. Now special
|
|
treatment in ssl/ssl_ciph.s makes sure that these ciphersuites
|
|
cannot be implicitly activated as part of, e.g., the "AES" alias.
|
|
However, please upgrade to OpenSSL 0.9.9[-dev] for
|
|
non-experimental use of the ECC ciphersuites to get TLS extension
|
|
support, which is required for curve and point format negotiation
|
|
to avoid potential handshake problems.
|
|
[Bodo Moeller]
|
|
|
|
*) Disable rogue ciphersuites:
|
|
|

- SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")

- SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
|

appear there.

[Bodo Moeller]
|
|
|
|
*) Fix RSA blinding Heisenbug (problems sometimes occurred on
|
|
dual-core machines) and other potential thread-safety issues.
|
|
[Bodo Moeller]
|
|
|
|
*) Add the symmetric cipher Camellia (128-bit, 192-bit, 256-bit key
|
|
versions), which is now available for royalty-free use
|
|
(see http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html).
|
|
Also, add Camellia TLS ciphersuites from RFC 4132.
|
|
|
|
To minimize changes between patchlevels in the OpenSSL 0.9.8
|
|
series, Camellia remains excluded from compilation unless OpenSSL
|
|
is configured with 'enable-camellia'.
|
|
[NTT]
|
|
|
|
*) Disable the padding bug check when compression is in use. The padding
|
|
bug check assumes the first packet is of even length, this is not
|
|
necessarily true if compression is enabled and can result in false
|
|
positives causing handshake failure. The actual bug test is ancient
|
|
code so it is hoped that implementations will either have fixed it by
|
|
now or any which still have the bug do not support compression.
|
|
[Steve Henson]
|
|
|
|
Changes between 0.9.8a and 0.9.8b [04 May 2006]
|
|
|
|
*) When applying a cipher rule check to see if string match is an explicit
|
|
cipher suite and only match that one cipher suite if it is.
|
|
[Steve Henson]
|
|
|
|
*) Link in manifests for VC++ if needed.
|
|
[Austin Ziegler <halostatue@gmail.com>]
|
|
|
|
*) Update support for ECC-based TLS ciphersuites according to
|
|
draft-ietf-tls-ecc-12.txt with proposed changes (but without
|
|
TLS extensions, which are supported starting with the 0.9.9
|
|
branch, not in the OpenSSL 0.9.8 branch).
|
|
[Douglas Stebila]
|
|
|
|
*) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support
|
|
opaque EVP_CIPHER_CTX handling.
|
|
[Steve Henson]
|
|
|
|
*) Fixes and enhancements to zlib compression code. We now only use
|
|
"zlib1.dll" and use the default __cdecl calling convention on Win32
|
|
to conform with the standards mentioned here:
|
|
http://www.zlib.net/DLL_FAQ.txt
|
|
Static zlib linking now works on Windows and the new --with-zlib-include
|
|
--with-zlib-lib options to Configure can be used to supply the location
|
|
of the headers and library. Gracefully handle case where zlib library
|
|
can't be loaded.
|
|
[Steve Henson]
|
|
|
|
*) Several fixes and enhancements to the OID generation code. The old code
|
|
sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't
|
|
handle numbers larger than ULONG_MAX, truncated printing and had a
|
|
non standard OBJ_obj2txt() behaviour.
|
|
[Steve Henson]
|
|
|
|
*) Add support for building of engines under engine/ as shared libraries
|
|
under VC++ build system.
|
|
[Steve Henson]
|
|
|
|
*) Corrected the numerous bugs in the Win32 path splitter in DSO.
|
|
Hopefully, we will not see any false combination of paths any more.
|
|
[Richard Levitte]
|
|
|
|
Changes between 0.9.8 and 0.9.8a [11 Oct 2005]
|
|
|
|
*) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
|
|
(part of SSL_OP_ALL). This option used to disable the
|
|
countermeasure against man-in-the-middle protocol-version
|
|
rollback in the SSL 2.0 server implementation, which is a bad
|
|
idea. (CVE-2005-2969)
|
|
|
|
[Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
|
|
for Information Security, National Institute of Advanced Industrial
|
|
Science and Technology [AIST], Japan)]
|
|
|
|
*) Add two function to clear and return the verify parameter flags.
|
|
[Steve Henson]
|
|
|
|
*) Keep cipherlists sorted in the source instead of sorting them at
|
|
runtime, thus removing the need for a lock.
|
|
[Nils Larsch]
|
|
|
|
*) Avoid some small subgroup attacks in Diffie-Hellman.
|
|
[Nick Mathewson and Ben Laurie]
|
|
|
|
*) Add functions for well-known primes.
|
|
[Nick Mathewson]
|
|
|
|
*) Extended Windows CE support.
|
|
[Satoshi Nakamura and Andy Polyakov]
|
|
|
|
*) Initialize SSL_METHOD structures at compile time instead of during
|
|
runtime, thus removing the need for a lock.
|
|
[Steve Henson]
|
|
|
|
*) Make PKCS7_decrypt() work even if no certificate is supplied by
|
|
attempting to decrypt each encrypted key in turn. Add support to
|
|
smime utility.
|
|
[Steve Henson]
|
|
|
|
Changes between 0.9.7h and 0.9.8 [05 Jul 2005]
|
|
|
|
[NB: OpenSSL 0.9.7i and later 0.9.7 patch levels were released after
|
|
OpenSSL 0.9.8.]
|
|
|
|
*) Add libcrypto.pc and libssl.pc for those who feel they need them.
|
|
[Richard Levitte]
|
|
|
|
*) Change CA.sh and CA.pl so they don't bundle the CSR and the private
|
|
key into the same file any more.
|
|
[Richard Levitte]
|
|
|
|
*) Add initial support for Win64, both IA64 and AMD64/x64 flavors.
|
|
[Andy Polyakov]
|
|
|
|
*) Add -utf8 command line and config file option to 'ca'.
|
|
[Stefan <stf@udoma.org]
|
|
|
|
*) Removed the macro des_crypt(), as it seems to conflict with some
|
|
libraries. Use DES_crypt().
|
|
[Richard Levitte]
|
|
|
|
*) Correct naming of the 'chil' and '4758cca' ENGINEs. This
|
|
involves renaming the source and generated shared-libs for
|
|
both. The engines will accept the corrected or legacy ids
|
|
('ncipher' and '4758_cca' respectively) when binding. NB,
|
|
this only applies when building 'shared'.
|
|
[Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe]
|
|
|
|
*) Add attribute functions to EVP_PKEY structure. Modify
|
|
PKCS12_create() to recognize a CSP name attribute and
|
|
use it. Make -CSP option work again in pkcs12 utility.
|
|
[Steve Henson]
|
|
|
|
*) Add new functionality to the bn blinding code:
|
|
- automatic re-creation of the BN_BLINDING parameters after
|
|
a fixed number of uses (currently 32)
|
|
- add new function for parameter creation
|
|
- introduce flags to control the update behaviour of the
|
|
BN_BLINDING parameters
|
|
- hide BN_BLINDING structure
|
|
Add a second BN_BLINDING slot to the RSA structure to improve
|
|
performance when a single RSA object is shared among several
|
|
threads.
|
|
[Nils Larsch]
|
|
|
|
*) Add support for DTLS.
|
|
[Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie]
|
|
|
|
*) Add support for DER encoded private keys (SSL_FILETYPE_ASN1)
|
|
to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file()
|
|
[Walter Goulet]
|
|
|
|
*) Remove buggy and incomplete DH cert support from
|
|
ssl/ssl_rsa.c and ssl/s3_both.c
|
|
[Nils Larsch]
|
|
|
|
*) Use SHA-1 instead of MD5 as the default digest algorithm for
|
|
the apps/openssl applications.
|
|
[Nils Larsch]
|
|
|
|
*) Compile clean with "-Wall -Wmissing-prototypes
|
|
-Wstrict-prototypes -Wmissing-declarations -Werror". Currently
|
|
DEBUG_SAFESTACK must also be set.
|
|
[Ben Laurie]
|
|
|
|
*) Change ./Configure so that certain algorithms can be disabled by default.
|
|
The new counterpiece to "no-xxx" is "enable-xxx".
|
|
|
|
The patented RC5 and MDC2 algorithms will now be disabled unless
|
|
"enable-rc5" and "enable-mdc2", respectively, are specified.
|
|
|
|
(IDEA remains enabled despite being patented. This is because IDEA
|
|
is frequently required for interoperability, and there is no license
|
|
fee for non-commercial use. As before, "no-idea" can be used to
|
|
avoid this algorithm.)
|
|
|
|
[Bodo Moeller]
|
|
|
|
*) Add processing of proxy certificates (see RFC 3820). This work was
|
|
sponsored by KTH (The Royal Institute of Technology in Stockholm) and
|
|
EGEE (Enabling Grids for E-science in Europe).
|
|
[Richard Levitte]
|
|
|
|
*) RC4 performance overhaul on modern architectures/implementations, such
|
|
as Intel P4, IA-64 and AMD64.
|
|
[Andy Polyakov]
|
|
|
|
*) New utility extract-section.pl. This can be used specify an alternative
|
|
section number in a pod file instead of having to treat each file as
|
|
a separate case in Makefile. This can be done by adding two lines to the
|
|
pod file:
|
|
|
|
=for comment openssl_section:XXX
|
|
|
|
The blank line is mandatory.
|
|
|
|
[Steve Henson]
|
|
|
|
*) New arguments -certform, -keyform and -pass for s_client and s_server
|
|
to allow alternative format key and certificate files and passphrase
|
|
sources.
|
|
[Steve Henson]
|
|
|
|
*) New structure X509_VERIFY_PARAM which combines current verify parameters,
|
|
update associated structures and add various utility functions.
|
|
|
|
Add new policy related verify parameters, include policy checking in
|
|
standard verify code. Enhance 'smime' application with extra parameters
|
|
to support policy checking and print out.
|
|
[Steve Henson]
|
|
|
|
*) Add a new engine to support VIA PadLock ACE extensions in the VIA C3
|
|
Nehemiah processors. These extensions support AES encryption in hardware
|
|
as well as RNG (though RNG support is currently disabled).
|
|
[Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov]
|
|
|
|
*) Deprecate BN_[get|set]_params() functions (they were ignored internally).
|
|
[Geoff Thorpe]
|
|
|
|
*) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented.
|
|
[Andy Polyakov and a number of other people]
|
|
|
|
*) Improved PowerPC platform support. Most notably BIGNUM assembler
|
|
implementation contributed by IBM.
|
|
[Suresh Chari, Peter Waltenberg, Andy Polyakov]
|
|
|
|
*) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public
|
|
exponent rather than 'unsigned long'. There is a corresponding change to
|
|
the new 'rsa_keygen' element of the RSA_METHOD structure.
|
|
[Jelte Jansen, Geoff Thorpe]
|
|
|
|
*) Functionality for creating the initial serial number file is now
|
|
moved from CA.pl to the 'ca' utility with a new option -create_serial.
|
|
|
|
(Before OpenSSL 0.9.7e, CA.pl used to initialize the serial
|
|
number file to 1, which is bound to cause problems. To avoid
|
|
the problems while respecting compatibility between different 0.9.7
|
|
patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in
|
|
CA.pl for serial number initialization. With the new release 0.9.8,
|
|
we can fix the problem directly in the 'ca' utility.)
|
|
[Steve Henson]
|
|
|
|
*) Reduced header interdependencies by declaring more opaque objects in
|
|
ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
|
|
give fewer recursive includes, which could break lazy source code - so
|
|
this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
|
|
developers should define this symbol when building and using openssl to
|
|
ensure they track the recommended behaviour, interfaces, [etc], but
|
|
backwards-compatible behaviour prevails when this isn't defined.
|
|
[Geoff Thorpe]
|
|
|
|
*) New function X509_POLICY_NODE_print() which prints out policy nodes.
|
|
[Steve Henson]
|
|
|
|
*) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
|
|
This will generate a random key of the appropriate length based on the
|
|
cipher context. The EVP_CIPHER can provide its own random key generation
|
|
routine to support keys of a specific form. This is used in the des and
|
|
3des routines to generate a key of the correct parity. Update S/MIME
|
|
code to use new functions and hence generate correct parity DES keys.
|
|
Add EVP_CHECK_DES_KEY #define to return an error if the key is not
|
|
valid (weak or incorrect parity).
|
|
[Steve Henson]
|
|
|
|
*) Add a local set of CRLs that can be used by X509_verify_cert() as well
|
|
as looking them up. This is useful when the verified structure may contain
|
|
CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
|
|
present unless the new PKCS7_NO_CRL flag is asserted.
|
|
[Steve Henson]
|
|
|
|
*) Extend ASN1 oid configuration module. It now additionally accepts the
|
|
syntax:
|
|
|
|
shortName = some long name, 1.2.3.4
|
|
[Steve Henson]
|
|
|
|
*) Reimplemented the BN_CTX implementation. There is now no more static
|
|
limitation on the number of variables it can handle nor the depth of the
|
|
"stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
|
|
information can now expand as required, and rather than having a single
|
|
static array of bignums, BN_CTX now uses a linked-list of such arrays
|
|
allowing it to expand on demand whilst maintaining the usefulness of
|
|
BN_CTX's "bundling".
|
|
[Geoff Thorpe]
|
|
|
|
*) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
|
|
to allow all RSA operations to function using a single BN_CTX.
|
|
[Geoff Thorpe]
|
|
|
|
*) Preliminary support for certificate policy evaluation and checking. This
|
|
is initially intended to pass the tests outlined in "Conformance Testing
|
|
of Relying Party Client Certificate Path Processing Logic" v1.07.
|
|
[Steve Henson]
|
|
|
|
*) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and
|
|
remained unused and not that useful. A variety of other little bignum
|
|
tweaks and fixes have also been made continuing on from the audit (see
|
|
below).
|
|
[Geoff Thorpe]
|
|
|
|
*) Constify all or almost all d2i, c2i, s2i and r2i functions, along with
|
|
associated ASN1, EVP and SSL functions and old ASN1 macros.
|
|
[Richard Levitte]
|
|
|
|
*) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
|
|
and this should never fail. So the return value from the use of
|
|
BN_set_word() (which can fail due to needless expansion) is now deprecated;
|
|
if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro.
|
|
[Geoff Thorpe]
|
|
|
|
*) BN_CTX_get() should return zero-valued bignums, providing the same
|
|
initialised value as BN_new().
|
|
[Geoff Thorpe, suggested by Ulf Möller]
|
|
|
|
*) Support for inhibitAnyPolicy certificate extension.
|
|
[Steve Henson]
|
|
|
|
*) An audit of the BIGNUM code is underway, for which debugging code is
|
|
enabled when BN_DEBUG is defined. This makes stricter enforcements on what
|
|
is considered valid when processing BIGNUMs, and causes execution to
|
|
assert() when a problem is discovered. If BN_DEBUG_RAND is defined,
|
|
further steps are taken to deliberately pollute unused data in BIGNUM
|
|
structures to try and expose faulty code further on. For now, openssl will
|
|
(in its default mode of operation) continue to tolerate the inconsistent
|
|
forms that it has tolerated in the past, but authors and packagers should
|
|
consider trying openssl and their own applications when compiled with
|
|
these debugging symbols defined. It will help highlight potential bugs in
|
|
their own code, and will improve the test coverage for OpenSSL itself. At
|
|
some point, these tighter rules will become openssl's default to improve
|
|
maintainability, though the assert()s and other overheads will remain only
|
|
in debugging configurations. See bn.h for more details.
|
|
[Geoff Thorpe, Nils Larsch, Ulf Möller]
|
|
|
|
*) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure
|
|
that can only be obtained through BN_CTX_new() (which implicitly
|
|
initialises it). The presence of this function only made it possible
|
|
to overwrite an existing structure (and cause memory leaks).
|
|
[Geoff Thorpe]
|
|
|
|
*) Because of the callback-based approach for implementing LHASH as a
|
|
template type, lh_insert() adds opaque objects to hash-tables and
|
|
lh_doall() or lh_doall_arg() are typically used with a destructor callback
|
|
to clean up those corresponding objects before destroying the hash table
|
|
(and losing the object pointers). So some over-zealous constifications in
|
|
LHASH have been relaxed so that lh_insert() does not take (nor store) the
|
|
objects as "const" and the lh_doall[_arg] callback wrappers are not
|
|
prototyped to have "const" restrictions on the object pointers they are
|
|
given (and so aren't required to cast them away any more).
|
|
[Geoff Thorpe]
|
|
|
|
*) The tmdiff.h API was so ugly and minimal that our own timing utility
|
|
(speed) prefers to use its own implementation. The two implementations
|
|
haven't been consolidated as yet (volunteers?) but the tmdiff API has had
|
|
its object type properly exposed (MS_TM) instead of casting to/from "char
|
|
*". This may still change yet if someone realises MS_TM and "ms_time_***"
|
|
aren't necessarily the greatest nomenclatures - but this is what was used
|
|
internally to the implementation so I've used that for now.
|
|
[Geoff Thorpe]
|
|
|
|
*) Ensure that deprecated functions do not get compiled when
|
|
OPENSSL_NO_DEPRECATED is defined. Some "openssl" subcommands and a few of
|
|
the self-tests were still using deprecated key-generation functions so
|
|
these have been updated also.
|
|
[Geoff Thorpe]
|
|
|
|
*) Reorganise PKCS#7 code to separate the digest location functionality
|
|
into PKCS7_find_digest(), digest addition into PKCS7_bio_add_digest().
|
|
New function PKCS7_set_digest() to set the digest type for PKCS#7
|
|
digestedData type. Add additional code to correctly generate the
|
|
digestedData type and add support for this type in PKCS7 initialization
|
|
functions.
|
|
[Steve Henson]
|
|
|
|
*) New function PKCS7_set0_type_other() this initializes a PKCS7
|
|
structure of type "other".
|
|
[Steve Henson]
|
|
|
|
*) Fix prime generation loop in crypto/bn/bn_prime.pl by making
|
|
sure the loop does correctly stop and breaking ("division by zero")
|
|
modulus operations are not performed. The (pre-generated) prime
|
|
table crypto/bn/bn_prime.h was already correct, but it could not be
|
|
re-generated on some platforms because of the "division by zero"
|
|
situation in the script.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Update support for ECC-based TLS ciphersuites according to
|
|
draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with
|
|
SHA-1 now is only used for "small" curves (where the
|
|
representation of a field element takes up to 24 bytes); for
|
|
larger curves, the field element resulting from ECDH is directly
|
|
used as premaster secret.
|
|
[Douglas Stebila (Sun Microsystems Laboratories)]
|
|
|
|
*) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2
|
|
curve secp160r1 to the tests.
|
|
[Douglas Stebila (Sun Microsystems Laboratories)]
|
|
|
|
*) Add the possibility to load symbols globally with DSO.
|
|
[Götz Babin-Ebell <babin-ebell@trustcenter.de> via Richard Levitte]
|
|
|
|
*) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better
|
|
control of the error stack.
|
|
[Richard Levitte]
|
|
|
|
*) Add support for STORE in ENGINE.
|
|
[Richard Levitte]
|
|
|
|
*) Add the STORE type. The intention is to provide a common interface
|
|
to certificate and key stores, be they simple file-based stores, or
|
|
HSM-type store, or LDAP stores, or...
|
|
NOTE: The code is currently UNTESTED and isn't really used anywhere.
|
|
[Richard Levitte]
|
|
|
|
*) Add a generic structure called OPENSSL_ITEM. This can be used to
|
|
pass a list of arguments to any function as well as provide a way
|
|
for a function to pass data back to the caller.
|
|
[Richard Levitte]
|
|
|
|
*) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup()
|
|
works like BUF_strdup() but can be used to duplicate a portion of
|
|
a string. The copy gets NUL-terminated. BUF_memdup() duplicates
|
|
a memory area.
|
|
[Richard Levitte]
|
|
|
|
*) Add the function sk_find_ex() which works like sk_find(), but will
|
|
return an index to an element even if an exact match couldn't be
|
|
found. The index is guaranteed to point at the element where the
|
|
searched-for key would be inserted to preserve sorting order.
|
|
[Richard Levitte]
|
|
|
|
*) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but
|
|
takes an extra flags argument for optional functionality. Currently,
|
|
the following flags are defined:
|
|
|
|
OBJ_BSEARCH_VALUE_ON_NOMATCH
|
|
This one gets OBJ_bsearch_ex() to return a pointer to the first
|
|
element where the comparing function returns a negative or zero
|
|
number.
|
|
|
|
OBJ_BSEARCH_FIRST_VALUE_ON_MATCH
|
|
This one gets OBJ_bsearch_ex() to return a pointer to the first
|
|
element where the comparing function returns zero. This is useful
|
|
if there are more than one element where the comparing function
|
|
returns zero.
|
|
[Richard Levitte]
|
|
|
|
*) Make it possible to create self-signed certificates with 'openssl ca'
|
|
in such a way that the self-signed certificate becomes part of the
|
|
CA database and uses the same mechanisms for serial number generation
|
|
as all other certificate signing. The new flag '-selfsign' enables
|
|
this functionality. Adapt CA.sh and CA.pl.in.
|
|
[Richard Levitte]
|
|
|
|
*) Add functionality to check the public key of a certificate request
|
|
against a given private. This is useful to check that a certificate
|
|
request can be signed by that key (self-signing).
|
|
[Richard Levitte]
|
|
|
|
*) Make it possible to have multiple active certificates with the same
|
|
subject in the CA index file. This is done only if the keyword
|
|
'unique_subject' is set to 'no' in the main CA section (default
|
|
if 'CA_default') of the configuration file. The value is saved
|
|
with the database itself in a separate index attribute file,
|
|
named like the index file with '.attr' appended to the name.
|
|
[Richard Levitte]
|
|
|
|
*) Generate multi-valued AVAs using '+' notation in config files for
|
|
req and dirName.
|
|
[Steve Henson]
|
|
|
|
*) Support for nameConstraints certificate extension.
|
|
[Steve Henson]
|
|
|
|
*) Support for policyConstraints certificate extension.
|
|
[Steve Henson]
|
|
|
|
*) Support for policyMappings certificate extension.
|
|
[Steve Henson]
|
|
|
|
*) Make sure the default DSA_METHOD implementation only uses its
|
|
dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL,
|
|
and change its own handlers to be NULL so as to remove unnecessary
|
|
indirection. This lets alternative implementations fallback to the
|
|
default implementation more easily.
|
|
[Geoff Thorpe]
|
|
|
|
*) Support for directoryName in GeneralName related extensions
|
|
in config files.
|
|
[Steve Henson]
|
|
|
|
*) Make it possible to link applications using Makefile.shared.
|
|
Make that possible even when linking against static libraries!
|
|
[Richard Levitte]
|
|
|
|
*) Support for single pass processing for S/MIME signing. This now
|
|
means that S/MIME signing can be done from a pipe, in addition
|
|
cleartext signing (multipart/signed type) is effectively streaming
|
|
and the signed data does not need to be all held in memory.
|
|
|
|
This is done with a new flag PKCS7_STREAM. When this flag is set
|
|
PKCS7_sign() only initializes the PKCS7 structure and the actual signing
|
|
is done after the data is output (and digests calculated) in
|
|
SMIME_write_PKCS7().
|
|
[Steve Henson]
|
|
|
|
*) Add full support for -rpath/-R, both in shared libraries and
|
|
applications, at least on the platforms where it's known how
|
|
to do it.
|
|
[Richard Levitte]
|
|
|
|
*) In crypto/ec/ec_mult.c, implement fast point multiplication with
|
|
precomputation, based on wNAF splitting: EC_GROUP_precompute_mult()
|
|
will now compute a table of multiples of the generator that
|
|
makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul()
|
|
faster (notably in the case of a single point multiplication,
|
|
scalar * generator).
|
|
[Nils Larsch, Bodo Moeller]
|
|
|
|
*) IPv6 support for certificate extensions. The various extensions
|
|
which use the IP:a.b.c.d can now take IPv6 addresses using the
|
|
formats of RFC1884 2.2 . IPv6 addresses are now also displayed
|
|
correctly.
|
|
[Steve Henson]
|
|
|
|
*) Added an ENGINE that implements RSA by performing private key
|
|
exponentiations with the GMP library. The conversions to and from
|
|
GMP's mpz_t format aren't optimised nor are any montgomery forms
|
|
cached, and on x86 it appears OpenSSL's own performance has caught up.
|
|
However there are likely to be other architectures where GMP could
|
|
provide a boost. This ENGINE is not built in by default, but it can be
|
|
specified at Configure time and should be accompanied by the necessary
|
|
linker additions, eg;
|
|
./config -DOPENSSL_USE_GMP -lgmp
|
|
[Geoff Thorpe]
|
|
|
|
*) "openssl engine" will not display ENGINE/DSO load failure errors when
|
|
testing availability of engines with "-t" - the old behaviour is
|
|
produced by increasing the feature's verbosity with "-tt".
|
|
[Geoff Thorpe]
|
|
|
|
*) ECDSA routines: under certain error conditions uninitialized BN objects
|
|
could be freed. Solution: make sure initialization is performed early
|
|
enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de>
|
|
via PR#459)
|
|
[Lutz Jaenicke]
|
|
|
|
*) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD
|
|
and DH_METHOD (eg. by ENGINE implementations) to override the normal
|
|
software implementations. For DSA and DH, parameter generation can
|
|
also be overridden by providing the appropriate method callbacks.
|
|
[Geoff Thorpe]
|
|
|
|
*) Change the "progress" mechanism used in key-generation and
|
|
primality testing to functions that take a new BN_GENCB pointer in
|
|
place of callback/argument pairs. The new API functions have "_ex"
|
|
postfixes and the older functions are reimplemented as wrappers for
|
|
the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide
|
|
declarations of the old functions to help (graceful) attempts to
|
|
migrate to the new functions. Also, the new key-generation API
|
|
functions operate on a caller-supplied key-structure and return
|
|
success/failure rather than returning a key or NULL - this is to
|
|
help make "keygen" another member function of RSA_METHOD etc.
|
|
|
|
Example for using the new callback interface:
|
|
|
|
int (*my_callback)(int a, int b, BN_GENCB *cb) = ...;
|
|
void *my_arg = ...;
|
|
BN_GENCB my_cb;
|
|
|
|
BN_GENCB_set(&my_cb, my_callback, my_arg);
|
|
|
|
return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb);
|
|
/* For the meaning of a, b in calls to my_callback(), see the
|
|
* documentation of the function that calls the callback.
|
|
* cb will point to my_cb; my_arg can be retrieved as cb->arg.
|
|
* my_callback should return 1 if it wants BN_is_prime_ex()
|
|
* to continue, or 0 to stop.
|
|
*/
|
|
|
|
[Geoff Thorpe]
|
|
|
|
*) Change the ZLIB compression method to be stateful, and make it
|
|
available to TLS with the number defined in
|
|
draft-ietf-tls-compression-04.txt.
|
|
[Richard Levitte]
|
|
|
|
*) Add the ASN.1 structures and functions for CertificatePair, which
|
|
is defined as follows (according to X.509_4thEditionDraftV6.pdf):
|
|
|
|
CertificatePair ::= SEQUENCE {
|
|
forward [0] Certificate OPTIONAL,
|
|
reverse [1] Certificate OPTIONAL,
|
|
-- at least one of the pair shall be present -- }
|
|
|
|
Also implement the PEM functions to read and write certificate
|
|
pairs, and defined the PEM tag as "CERTIFICATE PAIR".
|
|
|
|
This needed to be defined, mostly for the sake of the LDAP
|
|
attribute crossCertificatePair, but may prove useful elsewhere as
|
|
well.
|
|
[Richard Levitte]
|
|
|
|
*) Make it possible to inhibit symlinking of shared libraries in
|
|
Makefile.shared, for Cygwin's sake.
|
|
[Richard Levitte]
|
|
|
|
*) Extend the BIGNUM API by creating a function
|
|
void BN_set_negative(BIGNUM *a, int neg);
|
|
and a macro that behave like
|
|
int BN_is_negative(const BIGNUM *a);
|
|
|
|
to avoid the need to access 'a->neg' directly in applications.
|
|
[Nils Larsch]
|
|
|
|
*) Implement fast modular reduction for pseudo-Mersenne primes
|
|
used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
|
|
EC_GROUP_new_curve_GFp() will now automatically use this
|
|
if applicable.
|
|
[Nils Larsch <nla@trustcenter.de>]
|
|
|
|
*) Add new lock type (CRYPTO_LOCK_BN).
|
|
[Bodo Moeller]
|
|
|
|
*) Change the ENGINE framework to automatically load engines
|
|
dynamically from specific directories unless they could be
|
|
found to already be built in or loaded. Move all the
|
|
current engines except for the cryptodev one to a new
|
|
directory engines/.
|
|
The engines in engines/ are built as shared libraries if
|
|
the "shared" options was given to ./Configure or ./config.
|
|
Otherwise, they are inserted in libcrypto.a.
|
|
/usr/local/ssl/engines is the default directory for dynamic
|
|
engines, but that can be overridden at configure time through
|
|
the usual use of --prefix and/or --openssldir, and at run
|
|
time with the environment variable OPENSSL_ENGINES.
|
|
[Geoff Thorpe and Richard Levitte]
|
|
|
|
*) Add Makefile.shared, a helper makefile to build shared
|
|
libraries. Adapt Makefile.org.
|
|
[Richard Levitte]
|
|
|
|
*) Add version info to Win32 DLLs.
|
|
[Peter 'Luna' Runestig" <peter@runestig.com>]
|
|
|
|
*) Add new 'medium level' PKCS#12 API. Certificates and keys
|
|
can be added using this API to created arbitrary PKCS#12
|
|
files while avoiding the low level API.
|
|
|
|
New options to PKCS12_create(), key or cert can be NULL and
|
|
will then be omitted from the output file. The encryption
|
|
algorithm NIDs can be set to -1 for no encryption, the mac
|
|
iteration count can be set to 0 to omit the mac.
|
|
|
|
Enhance pkcs12 utility by making the -nokeys and -nocerts
|
|
options work when creating a PKCS#12 file. New option -nomac
|
|
to omit the mac, NONE can be set for an encryption algorithm.
|
|
New code is modified to use the enhanced PKCS12_create()
|
|
instead of the low level API.
|
|
[Steve Henson]
|
|
|
|
*) Extend ASN1 encoder to support indefinite length constructed
|
|
encoding. This can output sequences tags and octet strings in
|
|
this form. Modify pk7_asn1.c to support indefinite length
|
|
encoding. This is experimental and needs additional code to
|
|
be useful, such as an ASN1 bio and some enhanced streaming
|
|
PKCS#7 code.
|
|
|
|
Extend template encode functionality so that tagging is passed
|
|
down to the template encoder.
|
|
[Steve Henson]
|
|
|
|
*) Let 'openssl req' fail if an argument to '-newkey' is not
|
|
recognized instead of using RSA as a default.
|
|
[Bodo Moeller]
|
|
|
|
*) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
|
|
As these are not official, they are not included in "ALL";
|
|
the "ECCdraft" ciphersuite group alias can be used to select them.
|
|
[Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
|
|
|
|
*) Add ECDH engine support.
|
|
[Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
|
|
|
|
*) Add ECDH in new directory crypto/ecdh/.
|
|
[Douglas Stebila (Sun Microsystems Laboratories)]
|
|
|
|
*) Let BN_rand_range() abort with an error after 100 iterations
|
|
without success (which indicates a broken PRNG).
|
|
[Bodo Moeller]
|
|
|
|
*) Change BN_mod_sqrt() so that it verifies that the input value
|
|
is really the square of the return value. (Previously,
|
|
BN_mod_sqrt would show GIGO behaviour.)
|
|
[Bodo Moeller]
|
|
|
|
*) Add named elliptic curves over binary fields from X9.62, SECG,
|
|
and WAP/WTLS; add OIDs that were still missing.
|
|
|
|
[Sheueling Chang Shantz and Douglas Stebila
|
|
(Sun Microsystems Laboratories)]
|
|
|
|
*) Extend the EC library for elliptic curves over binary fields
|
|
(new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
|
|
New EC_METHOD:
|
|
|
|
EC_GF2m_simple_method
|
|
|
|
New API functions:
|
|
|
|
EC_GROUP_new_curve_GF2m
|
|
EC_GROUP_set_curve_GF2m
|
|
EC_GROUP_get_curve_GF2m
|
|
EC_POINT_set_affine_coordinates_GF2m
|
|
EC_POINT_get_affine_coordinates_GF2m
|
|
EC_POINT_set_compressed_coordinates_GF2m
|
|
|
|
Point compression for binary fields is disabled by default for
|
|
patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
|
|
enable it).
|
|
|
|
As binary polynomials are represented as BIGNUMs, various members
|
|
of the EC_GROUP and EC_POINT data structures can be shared
|
|
between the implementations for prime fields and binary fields;
|
|
the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
|
|
are essentially identical to their ..._GFp counterparts.
|
|
(For simplicity, the '..._GFp' prefix has been dropped from
|
|
various internal method names.)
|
|
|
|
An internal 'field_div' method (similar to 'field_mul' and
|
|
'field_sqr') has been added; this is used only for binary fields.
|
|
|
|
[Sheueling Chang Shantz and Douglas Stebila
|
|
(Sun Microsystems Laboratories)]
|
|
|
|
*) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
|
|
through methods ('mul', 'precompute_mult').
|
|
|
|
The generic implementations (now internally called 'ec_wNAF_mul'
|
|
and 'ec_wNAF_precomputed_mult') remain the default if these
|
|
methods are undefined.
|
|
|
|
[Sheueling Chang Shantz and Douglas Stebila
|
|
(Sun Microsystems Laboratories)]
|
|
|
|
*) New function EC_GROUP_get_degree, which is defined through
|
|
EC_METHOD. For curves over prime fields, this returns the bit
|
|
length of the modulus.
|
|
|
|
[Sheueling Chang Shantz and Douglas Stebila
|
|
(Sun Microsystems Laboratories)]
|
|
|
|
*) New functions EC_GROUP_dup, EC_POINT_dup.
|
|
(These simply call ..._new and ..._copy).
|
|
|
|
[Sheueling Chang Shantz and Douglas Stebila
|
|
(Sun Microsystems Laboratories)]
|
|
|
|
*) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
|
|
Polynomials are represented as BIGNUMs (where the sign bit is not
|
|
used) in the following functions [macros]:
|
|
|
|
BN_GF2m_add
|
|
BN_GF2m_sub [= BN_GF2m_add]
|
|
BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
|
|
BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
|
|
BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
|
|
BN_GF2m_mod_inv
|
|
BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
|
|
BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
|
|
BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
|
|
BN_GF2m_cmp [= BN_ucmp]
|
|
|
|
(Note that only the 'mod' functions are actually for fields GF(2^m).
|
|
BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
|
|
|
|
For some functions, an the irreducible polynomial defining a
|
|
field can be given as an 'unsigned int[]' with strictly
|
|
decreasing elements giving the indices of those bits that are set;
|
|
i.e., p[] represents the polynomial
|
|
f(t) = t^p[0] + t^p[1] + ... + t^p[k]
|
|
where
|
|
p[0] > p[1] > ... > p[k] = 0.
|
|
This applies to the following functions:
|
|
|
|
BN_GF2m_mod_arr
|
|
BN_GF2m_mod_mul_arr
|
|
BN_GF2m_mod_sqr_arr
|
|
BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
|
|
BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
|
|
BN_GF2m_mod_exp_arr
|
|
BN_GF2m_mod_sqrt_arr
|
|
BN_GF2m_mod_solve_quad_arr
|
|
BN_GF2m_poly2arr
|
|
BN_GF2m_arr2poly
|
|
|
|
Conversion can be performed by the following functions:
|
|
|
|
BN_GF2m_poly2arr
|
|
BN_GF2m_arr2poly
|
|
|
|
bntest.c has additional tests for binary polynomial arithmetic.
|
|
|
|
Two implementations for BN_GF2m_mod_div() are available.
|
|
The default algorithm simply uses BN_GF2m_mod_inv() and
|
|
BN_GF2m_mod_mul(). The alternative algorithm is compiled in only
|
|
if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
|
|
copyright notice in crypto/bn/bn_gf2m.c before enabling it).
|
|
|
|
[Sheueling Chang Shantz and Douglas Stebila
|
|
(Sun Microsystems Laboratories)]
|
|
|
|
*) Add new error code 'ERR_R_DISABLED' that can be used when some
|
|
functionality is disabled at compile-time.
|
|
[Douglas Stebila <douglas.stebila@sun.com>]
|
|
|
|
*) Change default behaviour of 'openssl asn1parse' so that more
|
|
information is visible when viewing, e.g., a certificate:
|
|
|
|
Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
|
|
mode the content of non-printable OCTET STRINGs is output in a
|
|
style similar to INTEGERs, but with '[HEX DUMP]' prepended to
|
|
avoid the appearance of a printable string.
|
|
[Nils Larsch <nla@trustcenter.de>]
|
|
|
|
*) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
|
|
functions
|
|
EC_GROUP_set_asn1_flag()
|
|
EC_GROUP_get_asn1_flag()
|
|
EC_GROUP_set_point_conversion_form()
|
|
EC_GROUP_get_point_conversion_form()
|
|
These control ASN1 encoding details:
|
|
- Curves (i.e., groups) are encoded explicitly unless asn1_flag
|
|
has been set to OPENSSL_EC_NAMED_CURVE.
|
|
- Points are encoded in uncompressed form by default; options for
|
|
asn1_for are as for point2oct, namely
|
|
POINT_CONVERSION_COMPRESSED
|
|
POINT_CONVERSION_UNCOMPRESSED
|
|
POINT_CONVERSION_HYBRID
|
|
|
|
Also add 'seed' and 'seed_len' members to EC_GROUP with access
|
|
functions
|
|
EC_GROUP_set_seed()
|
|
EC_GROUP_get0_seed()
|
|
EC_GROUP_get_seed_len()
|
|
This is used only for ASN1 purposes (so far).
|
|
[Nils Larsch <nla@trustcenter.de>]
|
|
|
|
*) Add 'field_type' member to EC_METHOD, which holds the NID
|
|
of the appropriate field type OID. The new function
|
|
EC_METHOD_get_field_type() returns this value.
|
|
[Nils Larsch <nla@trustcenter.de>]
|
|
|
|
*) Add functions
|
|
EC_POINT_point2bn()
|
|
EC_POINT_bn2point()
|
|
EC_POINT_point2hex()
|
|
EC_POINT_hex2point()
|
|
providing useful interfaces to EC_POINT_point2oct() and
|
|
EC_POINT_oct2point().
|
|
[Nils Larsch <nla@trustcenter.de>]
|
|
|
|
*) Change internals of the EC library so that the functions
|
|
EC_GROUP_set_generator()
|
|
EC_GROUP_get_generator()
|
|
EC_GROUP_get_order()
|
|
EC_GROUP_get_cofactor()
|
|
are implemented directly in crypto/ec/ec_lib.c and not dispatched
|
|
to methods, which would lead to unnecessary code duplication when
|
|
adding different types of curves.
|
|
[Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
|
|
|
|
*) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
|
|
arithmetic, and such that modified wNAFs are generated
|
|
(which avoid length expansion in many cases).
|
|
[Bodo Moeller]
|
|
|
|
*) Add a function EC_GROUP_check_discriminant() (defined via
|
|
EC_METHOD) that verifies that the curve discriminant is non-zero.
|
|
|
|
Add a function EC_GROUP_check() that makes some sanity tests
|
|
on a EC_GROUP, its generator and order. This includes
|
|
EC_GROUP_check_discriminant().
|
|
[Nils Larsch <nla@trustcenter.de>]
|
|
|
|
*) Add ECDSA in new directory crypto/ecdsa/.
|
|
|
|
Add applications 'openssl ecparam' and 'openssl ecdsa'
|
|
(these are based on 'openssl dsaparam' and 'openssl dsa').
|
|
|
|
ECDSA support is also included in various other files across the
|
|
library. Most notably,
|
|
- 'openssl req' now has a '-newkey ecdsa:file' option;
|
|
- EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
|
|
- X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
|
|
d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
|
|
them suitable for ECDSA where domain parameters must be
|
|
extracted before the specific public key;
|
|
- ECDSA engine support has been added.
|
|
[Nils Larsch <nla@trustcenter.de>]
|
|
|
|
*) Include some named elliptic curves, and add OIDs from X9.62,
|
|
SECG, and WAP/WTLS. Each curve can be obtained from the new
|
|
function
|
|
EC_GROUP_new_by_curve_name(),
|
|
and the list of available named curves can be obtained with
|
|
EC_get_builtin_curves().
|
|
Also add a 'curve_name' member to EC_GROUP objects, which can be
|
|
accessed via
|
|
EC_GROUP_set_curve_name()
|
|
EC_GROUP_get_curve_name()
|
|
[Nils Larsch <larsch@trustcenter.de, Bodo Moeller]
|
|
|
|
*) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
|
|
was actually never needed) and in BN_mul(). The removal in BN_mul()
|
|
required a small change in bn_mul_part_recursive() and the addition
|
|
of the functions bn_cmp_part_words(), bn_sub_part_words() and
|
|
bn_add_part_words(), which do the same thing as bn_cmp_words(),
|
|
bn_sub_words() and bn_add_words() except they take arrays with
|
|
differing sizes.
|
|
[Richard Levitte]
|
|
|
|
Changes between 0.9.7l and 0.9.7m [23 Feb 2007]
|
|
|
|
*) Cleanse PEM buffers before freeing them since they may contain
|
|
sensitive data.
|
|
[Benjamin Bennett <ben@psc.edu>]
|
|
|
|
*) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that
|
|
a ciphersuite string such as "DEFAULT:RSA" cannot enable
|
|
authentication-only ciphersuites.
|
|
[Bodo Moeller]
|
|
|
|
*) Since AES128 and AES256 share a single mask bit in the logic of
|
|
ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a
|
|
kludge to work properly if AES128 is available and AES256 isn't.
|
|
[Victor Duchovni]
|
|
|
|
*) Expand security boundary to match 1.1.1 module.
|
|
[Steve Henson]
|
|
|
|
*) Remove redundant features: hash file source, editing of test vectors
|
|
modify fipsld to use external fips_premain.c signature.
|
|
[Steve Henson]
|
|
|
|
*) New perl script mkfipsscr.pl to create shell scripts or batch files to
|
|
run algorithm test programs.
|
|
[Steve Henson]
|
|
|
|
*) Make algorithm test programs more tolerant of whitespace.
|
|
[Steve Henson]
|
|
|
|
*) Have SSL/TLS server implementation tolerate "mismatched" record
|
|
protocol version while receiving ClientHello even if the
|
|
ClientHello is fragmented. (The server can't insist on the
|
|
particular protocol version it has chosen before the ServerHello
|
|
message has informed the client about his choice.)
|
|
[Bodo Moeller]
|
|
|
|
*) Load error codes if they are not already present instead of using a
|
|
static variable. This allows them to be cleanly unloaded and reloaded.
|
|
[Steve Henson]
|
|
|
|
Changes between 0.9.7k and 0.9.7l [28 Sep 2006]
|
|
|
|
*) Introduce limits to prevent malicious keys being able to
|
|
cause a denial of service. (CVE-2006-2940)
|
|
[Steve Henson, Bodo Moeller]
|
|
|
|
*) Fix ASN.1 parsing of certain invalid structures that can result
|
|
in a denial of service. (CVE-2006-2937) [Steve Henson]
|
|
|
|
*) Fix buffer overflow in SSL_get_shared_ciphers() function.
|
|
(CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team]
|
|
|
|
*) Fix SSL client code which could crash if connecting to a
|
|
malicious SSLv2 server. (CVE-2006-4343)
|
|
[Tavis Ormandy and Will Drewry, Google Security Team]
|
|
|
|
*) Change ciphersuite string processing so that an explicit
|
|
ciphersuite selects this one ciphersuite (so that "AES256-SHA"
|
|
will no longer include "AES128-SHA"), and any other similar
|
|
ciphersuite (same bitmap) from *other* protocol versions (so that
|
|
"RC4-MD5" will still include both the SSL 2.0 ciphersuite and the
|
|
SSL 3.0/TLS 1.0 ciphersuite). This is a backport combining
|
|
changes from 0.9.8b and 0.9.8d.
|
|
[Bodo Moeller]
|
|
|
|
Changes between 0.9.7j and 0.9.7k [05 Sep 2006]
|
|
|
|
*) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher
|
|
(CVE-2006-4339) [Ben Laurie and Google Security Team]
|
|
|
|
*) Change the Unix randomness entropy gathering to use poll() when
|
|
possible instead of select(), since the latter has some
|
|
undesirable limitations.
|
|
[Darryl Miles via Richard Levitte and Bodo Moeller]
|
|
|
|
*) Disable rogue ciphersuites:
|
|
|
|
- SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
|
|
- SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
|
|
- SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
|
|
|
|
The latter two were purportedly from
|
|
draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
|
|
appear there.
|
|
|
|
Also deactivate the remaining ciphersuites from
|
|
draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as
|
|
unofficial, and the ID has long expired.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix RSA blinding Heisenbug (problems sometimes occurred on
|
|
dual-core machines) and other potential thread-safety issues.
|
|
[Bodo Moeller]
|
|
|
|
Changes between 0.9.7i and 0.9.7j [04 May 2006]
|
|
|
|
*) Adapt fipsld and the build system to link against the validated FIPS
|
|
module in FIPS mode.
|
|
[Steve Henson]
|
|
|
|
*) Fixes for VC++ 2005 build under Windows.
|
|
[Steve Henson]
|
|
|
|
*) Add new Windows build target VC-32-GMAKE for VC++. This uses GNU make
|
|
from a Windows bash shell such as MSYS. It is autodetected from the
|
|
"config" script when run from a VC++ environment. Modify standard VC++
|
|
build to use fipscanister.o from the GNU make build.
|
|
[Steve Henson]
|
|
|
|
Changes between 0.9.7h and 0.9.7i [14 Oct 2005]
|
|
|
|
*) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS.
|
|
The value now differs depending on if you build for FIPS or not.
|
|
BEWARE! A program linked with a shared FIPSed libcrypto can't be
|
|
safely run with a non-FIPSed libcrypto, as it may crash because of
|
|
the difference induced by this change.
|
|
[Andy Polyakov]
|
|
|
|
Changes between 0.9.7g and 0.9.7h [11 Oct 2005]
|
|
|
|
*) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
|
|
(part of SSL_OP_ALL). This option used to disable the
|
|
countermeasure against man-in-the-middle protocol-version
|
|
rollback in the SSL 2.0 server implementation, which is a bad
|
|
idea. (CVE-2005-2969)
|
|
|
|
[Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
|
|
for Information Security, National Institute of Advanced Industrial
|
|
Science and Technology [AIST], Japan)]
|
|
|
|
*) Minimal support for X9.31 signatures and PSS padding modes. This is
|
|
mainly for FIPS compliance and not fully integrated at this stage.
|
|
[Steve Henson]
|
|
|
|
*) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform
|
|
the exponentiation using a fixed-length exponent. (Otherwise,
|
|
the information leaked through timing could expose the secret key
|
|
after many signatures; cf. Bleichenbacher's attack on DSA with
|
|
biased k.)
|
|
[Bodo Moeller]
|
|
|
|
*) Make a new fixed-window mod_exp implementation the default for
|
|
RSA, DSA, and DH private-key operations so that the sequence of
|
|
squares and multiplies and the memory access pattern are
|
|
independent of the particular secret key. This will mitigate
|
|
cache-timing and potential related attacks.
|
|
|
|
BN_mod_exp_mont_consttime() is the new exponentiation implementation,
|
|
and this is automatically used by BN_mod_exp_mont() if the new flag
|
|
BN_FLG_EXP_CONSTTIME is set for the exponent. RSA, DSA, and DH
|
|
will use this BN flag for private exponents unless the flag
|
|
RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or
|
|
DH_FLAG_NO_EXP_CONSTTIME, respectively, is set.
|
|
|
|
[Matthew D Wood (Intel Corp), with some changes by Bodo Moeller]
|
|
|
|
*) Change the client implementation for SSLv23_method() and
|
|
SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0
|
|
Client Hello message format if the SSL_OP_NO_SSLv2 option is set.
|
|
(Previously, the SSL 2.0 backwards compatible Client Hello
|
|
message format would be used even with SSL_OP_NO_SSLv2.)
|
|
[Bodo Moeller]
|
|
|
|
*) Add support for smime-type MIME parameter in S/MIME messages which some
|
|
clients need.
|
|
[Steve Henson]
|
|
|
|
*) New function BN_MONT_CTX_set_locked() to set montgomery parameters in
|
|
a threadsafe manner. Modify rsa code to use new function and add calls
|
|
to dsa and dh code (which had race conditions before).
|
|
[Steve Henson]
|
|
|
|
*) Include the fixed error library code in the C error file definitions
|
|
instead of fixing them up at runtime. This keeps the error code
|
|
structures constant.
|
|
[Steve Henson]
|
|
|
|
Changes between 0.9.7f and 0.9.7g [11 Apr 2005]
|
|
|
|
[NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after
|
|
OpenSSL 0.9.8.]
|
|
|
|
*) Fixes for newer kerberos headers. NB: the casts are needed because
|
|
the 'length' field is signed on one version and unsigned on another
|
|
with no (?) obvious way to tell the difference, without these VC++
|
|
complains. Also the "definition" of FAR (blank) is no longer included
|
|
nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up
|
|
some needed definitions.
|
|
[Steve Henson]
|
|
|
|
*) Undo Cygwin change.
|
|
[Ulf Möller]
|
|
|
|
*) Added support for proxy certificates according to RFC 3820.
|
|
Because they may be a security thread to unaware applications,
|
|
they must be explicitly allowed in run-time. See
|
|
docs/HOWTO/proxy_certificates.txt for further information.
|
|
[Richard Levitte]
|
|
|
|
Changes between 0.9.7e and 0.9.7f [22 Mar 2005]
|
|
|
|
*) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating
|
|
server and client random values. Previously
|
|
(SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in
|
|
less random data when sizeof(time_t) > 4 (some 64 bit platforms).
|
|
|
|
This change has negligible security impact because:
|
|
|
|
1. Server and client random values still have 24 bytes of pseudo random
|
|
data.
|
|
|
|
2. Server and client random values are sent in the clear in the initial
|
|
handshake.
|
|
|
|
3. The master secret is derived using the premaster secret (48 bytes in
|
|
size for static RSA ciphersuites) as well as client server and random
|
|
values.
|
|
|
|
The OpenSSL team would like to thank the UK NISCC for bringing this issue
|
|
to our attention.
|
|
|
|
[Stephen Henson, reported by UK NISCC]
|
|
|
|
*) Use Windows randomness collection on Cygwin.
|
|
[Ulf Möller]
|
|
|
|
*) Fix hang in EGD/PRNGD query when communication socket is closed
|
|
prematurely by EGD/PRNGD.
|
|
[Darren Tucker <dtucker@zip.com.au> via Lutz Jänicke, resolves #1014]
|
|
|
|
*) Prompt for pass phrases when appropriate for PKCS12 input format.
|
|
[Steve Henson]
|
|
|
|
*) Back-port of selected performance improvements from development
|
|
branch, as well as improved support for PowerPC platforms.
|
|
[Andy Polyakov]
|
|
|
|
*) Add lots of checks for memory allocation failure, error codes to indicate
|
|
failure and freeing up memory if a failure occurs.
|
|
[Nauticus Networks SSL Team <openssl@nauticusnet.com>, Steve Henson]
|
|
|
|
*) Add new -passin argument to dgst.
|
|
[Steve Henson]
|
|
|
|
*) Perform some character comparisons of different types in X509_NAME_cmp:
|
|
this is needed for some certificates that re-encode DNs into UTF8Strings
|
|
(in violation of RFC3280) and can't or won't issue name rollover
|
|
certificates.
|
|
[Steve Henson]
|
|
|
|
*) Make an explicit check during certificate validation to see that
|
|
the CA setting in each certificate on the chain is correct. As a
|
|
side effect always do the following basic checks on extensions,
|
|
not just when there's an associated purpose to the check:
|
|
|
|
- if there is an unhandled critical extension (unless the user
|
|
has chosen to ignore this fault)
|
|
- if the path length has been exceeded (if one is set at all)
|
|
- that certain extensions fit the associated purpose (if one has
|
|
been given)
|
|
[Richard Levitte]
|
|
|
|
Changes between 0.9.7d and 0.9.7e [25 Oct 2004]
|
|
|
|
*) Avoid a race condition when CRLs are checked in a multi threaded
|
|
environment. This would happen due to the reordering of the revoked
|
|
entries during signature checking and serial number lookup. Now the
|
|
encoding is cached and the serial number sort performed under a lock.
|
|
Add new STACK function sk_is_sorted().
|
|
[Steve Henson]
|
|
|
|
*) Add Delta CRL to the extension code.
|
|
[Steve Henson]
|
|
|
|
*) Various fixes to s3_pkt.c so alerts are sent properly.
|
|
[David Holmes <d.holmes@f5.com>]
|
|
|
|
*) Reduce the chances of duplicate issuer name and serial numbers (in
|
|
violation of RFC3280) using the OpenSSL certificate creation utilities.
|
|
This is done by creating a random 64 bit value for the initial serial
|
|
number when a serial number file is created or when a self signed
|
|
certificate is created using 'openssl req -x509'. The initial serial
|
|
number file is created using 'openssl x509 -next_serial' in CA.pl
|
|
rather than being initialized to 1.

|
[Steve Henson]
|
|
|
|
Changes between 0.9.7c and 0.9.7d [17 Mar 2004]
|
|
|
|
*) Fix null-pointer assignment in do_change_cipher_spec() revealed
|
|
by using the Codenomicon TLS Test Tool (CVE-2004-0079)
|
|
[Joe Orton, Steve Henson]
|
|
|
|
*) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites
|
|
(CVE-2004-0112)
|
|
[Joe Orton, Steve Henson]
|
|
|
|
*) Make it possible to have multiple active certificates with the same
|
|
subject in the CA index file. This is done only if the keyword
|
|
'unique_subject' is set to 'no' in the main CA section (default
|
|
if 'CA_default') of the configuration file. The value is saved
|
|
with the database itself in a separate index attribute file,
|
|
named like the index file with '.attr' appended to the name.
|
|
[Richard Levitte]
|
|
|
|
*) X509 verify fixes. Disable broken certificate workarounds when
|
|
X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if
|
|
keyUsage extension present. Don't accept CRLs with unhandled critical
|
|
extensions: since verify currently doesn't process CRL extensions this
|
|
rejects a CRL with *any* critical extensions. Add new verify error codes
|
|
for these cases.
|
|
[Steve Henson]
|
|
|
|
*) When creating an OCSP nonce use an OCTET STRING inside the extnValue.
|
|
A clarification of RFC2560 will require the use of OCTET STRINGs and
|
|
some implementations cannot handle the current raw format. Since OpenSSL
|
|
copies and compares OCSP nonces as opaque blobs without any attempt at
|
|
parsing them this should not create any compatibility issues.
|
|
[Steve Henson]
|
|
|
|
*) New md flag EVP_MD_CTX_FLAG_REUSE this allows md_data to be reused when
|
|
calling EVP_MD_CTX_copy_ex() to avoid calling OPENSSL_malloc(). Without
|
|
this HMAC (and other) operations are several times slower than OpenSSL
|
|
< 0.9.7.
|
|
[Steve Henson]
|
|
|
|
*) Print out GeneralizedTime and UTCTime in ASN1_STRING_print_ex().
|
|
[Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
|
|
|
|
*) Use the correct content when signing type "other".

|
[Steve Henson]
|
|
|
|
Changes between 0.9.7b and 0.9.7c [30 Sep 2003]
|
|
|
|
*) Fix various bugs revealed by running the NISCC test suite:
|
|
|
|
Stop out of bounds reads in the ASN1 code when presented with
|
|
invalid tags (CVE-2003-0543 and CVE-2003-0544).
|
|
|
|
Free up ASN1_TYPE correctly if ANY type is invalid (CVE-2003-0545).
|
|
|
|
If verify callback ignores invalid public key errors don't try to check
|
|
certificate signature with the NULL public key.
|
|
|
|
[Steve Henson]
|
|
|
|
*) New -ignore_err option in ocsp application to stop the server
|
|
exiting on the first error in a request.
|
|
[Steve Henson]
|
|
|
|
*) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
|
|
if the server requested one: as stated in TLS 1.0 and SSL 3.0
|
|
specifications.
|
|
[Steve Henson]
|
|
|
|
*) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
|
|
extra data after the compression methods not only for TLS 1.0
|
|
but also for SSL 3.0 (as required by the specification).
|
|
[Bodo Moeller; problem pointed out by Matthias Loepfe]
|
|
|
|
*) Change X509_certificate_type() to mark the key as exported/exportable
|
|
when it's 512 *bits* long, not 512 bytes.
|
|
[Richard Levitte]
|
|
|
|
*) Change AES_cbc_encrypt() so it outputs exact multiple of
|
|
blocks during encryption.
|
|
[Richard Levitte]
|
|
|
|
*) Various fixes to base64 BIO and non blocking I/O. On write
|
|
flushes were not handled properly if the BIO retried. On read
|
|
data was not being buffered properly and had various logic bugs.
|
|
This also affects blocking I/O when the data being decoded is a
|
|
certain size.
|
|
[Steve Henson]
|
|
|
|
*) Various S/MIME bugfixes and compatibility changes:
|
|
output correct application/pkcs7 MIME type if
|
|
PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures.
|
|
Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening
|
|
of files as .eml work). Correctly handle very long lines in MIME
|
|
parser.
|
|
[Steve Henson]
|
|
|
|
Changes between 0.9.7a and 0.9.7b [10 Apr 2003]
|
|
|
|
*) Countermeasure against the Klima-Pokorny-Rosa extension of
|
|
Bleichbacher's attack on PKCS #1 v1.5 padding: treat
|
|
a protocol version number mismatch like a decryption error
|
|
in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
|
|
[Bodo Moeller]
|
|
|
|
*) Turn on RSA blinding by default in the default implementation
|
|
to avoid a timing attack. Applications that don't want it can call
|
|
RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
|
|
They would be ill-advised to do so in most cases.
|
|
[Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
|
|
|
|
*) Change RSA blinding code so that it works when the PRNG is not
|
|
seeded (in this case, the secret RSA exponent is abused as
|
|
an unpredictable seed -- if it is not unpredictable, there
|
|
is no point in blinding anyway). Make RSA blinding thread-safe
|
|
by remembering the creator's thread ID in rsa->blinding and
|
|
having all other threads use local one-time blinding factors
|
|
(this requires more computation than sharing rsa->blinding, but
|
|
avoids excessive locking; and if an RSA object is not shared
|
|
between threads, blinding will still be very fast).
|
|
[Bodo Moeller]
|
|
|
|
*) Fixed a typo bug that would cause ENGINE_set_default() to set an
|
|
ENGINE as defaults for all supported algorithms irrespective of
|
|
the 'flags' parameter. 'flags' is now honoured, so applications
|
|
should make sure they are passing it correctly.
|
|
[Geoff Thorpe]
|
|
|
|
*) Target "mingw" now allows native Windows code to be generated in
|
|
the Cygwin environment as well as with the MinGW compiler.

|
[Ulf Moeller]
|
|
|
|
Changes between 0.9.7 and 0.9.7a [19 Feb 2003]
|
|
|
|
*) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
|
|
via timing by performing a MAC computation even if incorrect
|
|
block cipher padding has been found. This is a countermeasure
|
|
against active attacks where the attacker has to distinguish
|
|
between bad padding and a MAC verification error. (CVE-2003-0078)
|
|
|
|
[Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
|
|
Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
|
|
Martin Vuagnoux (EPFL, Ilion)]
|
|
|
|
*) Make the no-err option work as intended. The intention with no-err
|
|
is not to have the whole error stack handling routines removed from
|
|
libcrypto, it's only intended to remove all the function name and
|
|
reason texts, thereby removing some of the footprint that may not
|
|
be interesting if those errors aren't displayed anyway.
|
|
|
|
NOTE: it's still possible for any application or module to have its
|
|
own set of error texts inserted. The routines are there, just not
|
|
used by default when no-err is given.
|
|
[Richard Levitte]
|
|
|
|
*) Add support for FreeBSD on IA64.
|
|
[dirk.meyer@dinoex.sub.org via Richard Levitte, resolves #454]
|
|
|
|
*) Adjust DES_cbc_cksum() so it returns the same value as the MIT
|
|
Kerberos function mit_des_cbc_cksum(). Before this change,
|
|
the value returned by DES_cbc_cksum() was like the one from
|
|
mit_des_cbc_cksum(), except the bytes were swapped.
|
|
[Kevin Greaney <Kevin.Greaney@hp.com> and Richard Levitte]
|
|
|
|
*) Allow an application to disable the automatic SSL chain building.
|
|
Before this a rather primitive chain build was always performed in
|
|
ssl3_output_cert_chain(): an application had no way to send the
|
|
correct chain if the automatic operation produced an incorrect result.
|
|
|
|
Now the chain builder is disabled if either:
|
|
|
|
1. Extra certificates are added via SSL_CTX_add_extra_chain_cert().
|
|
|
|
2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set.
|
|
|
|
The reasoning behind this is that an application would not want the
|
|
auto chain building to take place if extra chain certificates are
|
|
present and it might also want a means of sending no additional
|
|
certificates (for example the chain has two certificates and the
|
|
root is omitted).
|
|
[Steve Henson]
|
|
|
|
*) Add the possibility to build without the ENGINE framework.
|
|
[Steven Reddie <smr@essemer.com.au> via Richard Levitte]
|
|
|
|
*) Under Win32 gmtime() can return NULL: check return value in
|
|
OPENSSL_gmtime(). Add error code for case where gmtime() fails.
|
|
[Steve Henson]
|
|
|
|
*) DSA routines: under certain error conditions uninitialized BN objects
|
|
could be freed. Solution: make sure initialization is performed early

|
|
[Lutz Jaenicke]
|
|
|
|
*) Another fix for SSLv2 session ID handling: the session ID was incorrectly
|
|
checked on reconnect on the client side, therefore session resumption
|
|
could still fail with a "ssl session id is different" error. This
|
|
behaviour is masked when SSL_OP_ALL is used due to
|
|
SSL_OP_MICROSOFT_SESS_ID_BUG being set.
|
|
Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
|
|
followup to PR #377.

*) IA-32 assembler support enhancements: unified ELF targets, support
|
|
for SCO/Caldera platforms, fix for Cygwin shared build.
|
|
[Andy Polyakov]
|
|
|
|
*) Add support for FreeBSD on sparc64. As a consequence, support for
|
|
FreeBSD on non-x86 processors is separate from x86 processors on
|
|
the config script, much like the NetBSD support.

Changes between 0.9.6h and 0.9.7 [31 Dec 2002]
|
|
|
|
[NB: OpenSSL 0.9.6i and later 0.9.6 patch levels were released after
|
|
OpenSSL 0.9.7.]
|
|
|
|
*) Fix session ID handling in SSLv2 client code: the SERVER FINISHED
|
|
code (06) was taken as the first octet of the session ID and the last
|
|
octet was ignored consequently. As a result SSLv2 client side session
|
|
caching could not have worked due to the session ID mismatch between
|
|
client and server.
|
|
Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
|
|
PR #377.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Change the declaration of needed Kerberos libraries to use EX_LIBS
|
|
instead of the special (and badly supported) LIBKRB5. LIBKRB5 is
|
|
removed entirely.
|
|
[Richard Levitte]
|
|
|
|
*) The hw_ncipher.c engine requires dynamic locks. Unfortunately, it
|
|
seems that in spite of existing for more than a year, many application
|
|
author have done nothing to provide the necessary callbacks, which
|
|
means that this particular engine will not work properly anywhere.
|
|
This is a very unfortunate situation which forces us, in the name
|
|
of usability, to give the hw_ncipher.c a static lock, which is part
|
|
of libcrypto.
|
|
NOTE: This is for the 0.9.7 series ONLY. This hack will never
|
|
appear in 0.9.8 or later. We EXPECT application authors to have
|
|
dealt properly with this when 0.9.8 is released (unless we actually
|
|
make such changes in the libcrypto locking code that changes will
|
|
have to be made anyway).
|
|
[Richard Levitte]
|
|
|
|
*) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content
|
|
octets have been read, EOF or an error occurs. Without this change
|
|
some truncated ASN1 structures will not produce an error.
|
|
[Steve Henson]
|
|
|
|
*) Disable Heimdal support, since it hasn't been fully implemented.
|
|
Still give the possibility to force the use of Heimdal, but with
|
|
warnings and a request that patches get sent to openssl-dev.
|
|
[Richard Levitte]
|
|
|
|
*) Add the VC-CE target, introduce the WINCE sysname, and add
|
|
INSTALL.WCE and appropriate conditionals to make it build.
|
|
[Steven Reddie <smr@essemer.com.au> via Richard Levitte]
|
|
|
|
*) Change the DLL names for Cygwin to cygcrypto-x.y.z.dll and
|
|
cygssl-x.y.z.dll, where x, y and z are the major, minor and
|
|
edit numbers of the version.
|
|
[Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
|
|
|
|
*) Introduce safe string copy and catenation functions
|
|
(BUF_strlcpy() and BUF_strlcat()).
|
|
[Ben Laurie (CHATS) and Richard Levitte]
|
|
|
|
*) Avoid using fixed-size buffers for one-line DNs.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Add BUF_MEM_grow_clean() to avoid information leakage when
|
|
resizing buffers containing secrets, and use where appropriate.

[Ben Laurie (CHATS)]
|
|
|
|
*) Avoid using fixed size buffers for configuration file location.

|
[Ben Laurie (CHATS)]
|
|
|

*) Avoid filename truncation for various CA files.
|
|
[Ben Laurie (CHATS)]
|
|
|

*) Use sizeof in preference to magic numbers.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Avoid filename truncation in cert requests.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Add assertions to check for (supposedly impossible) buffer
|
|
overflows.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Don't cache truncated DNS entries in the local cache (this could
|
|
potentially lead to a spoofing attack).
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Fix various buffers to be large enough for hex/decimal
|
|
representations in a platform independent manner.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Add CRYPTO_realloc_clean() to avoid information leakage when
|
|
resizing buffers containing secrets, and use where appropriate.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Add BIO_indent() to avoid much slightly worrying code to do
|
|
indents.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Convert sprintf()/BIO_puts() to BIO_printf().
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) buffer_gets() could terminate with the buffer only half
|
|
full. Fixed.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Add assertions to prevent user-supplied crypto functions from
|
|
overflowing internal buffers by having large block sizes, etc.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) New OPENSSL_assert() macro (similar to assert(), but enabled
|
|
unconditionally).
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Eliminate unused copy of key in RC4.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Eliminate unused and incorrectly sized buffers for IV in pem.h.

|
[Ben Laurie (CHATS)]

|
|
|
*) Eliminate unused and incorrectly sized X.509 structure

[Ben Laurie (CHATS)]
|
|

|
[Ben Laurie (CHATS)]
|
|
|
|
*) Protect against overlong session ID context length in an encoded
|
|
session object. Since these are local, this does not appear to be

exploitable.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Change from security patch (see 0.9.6e below) that did not affect
|
|
the 0.9.6 release series:
|
|
|
|
Remote buffer overflow in SSL3 protocol - an attacker could
|
|
supply an oversized master key in Kerberos-enabled versions.
|
|
(CVE-2002-0657)
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Change the SSL kerb5 codes to match RFC 2712.
|
|
[Richard Levitte]
|
|
|
|
*) Make -nameopt work fully for req and add -reqopt switch.
|
|
[Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
|
|
|
|
*) The "block size" for block ciphers in CFB and OFB mode should be 1.
|
|
[Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
|
|
|
|
*) Make sure tests can be performed even if the corresponding algorithms
|
|
have been removed entirely. This was also the last step to make
|
|
OpenSSL compilable with DJGPP under all reasonable conditions.
|
|
[Richard Levitte, Doug Kaufman <dkaufman@rahul.net>]
|
|
|
|
*) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT
|
|
to allow version independent disabling of normally unselected ciphers,
|
|
which may be activated as a side-effect of selecting a single cipher.
|
|
|
|
(E.g., cipher list string "RSA" enables ciphersuites that are left
|
|
out of "ALL" because they do not provide symmetric encryption.
|
|
"RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.)
|
|
[Lutz Jaenicke, Bodo Moeller]
|
|
|
|
*) Add appropriate support for separate platform-dependent build
|
|
directories. The recommended way to make a platform-dependent
|
|
build directory is the following (tested on Linux), maybe with
|
|
some local tweaks:
|
|
|
|
# Place yourself outside of the OpenSSL source tree. In
|
|
# this example, the environment variable OPENSSL_SOURCE
|
|
# is assumed to contain the absolute OpenSSL source directory.
|
|
mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
|
|
cd objtree/"`uname -s`-`uname -r`-`uname -m`"
|
|
(cd $OPENSSL_SOURCE; find . -type f) | while read F; do
|
|
mkdir -p `dirname $F`
|
|
ln -s $OPENSSL_SOURCE/$F $F
|
|
done
|
|
|
|
To be absolutely sure not to disturb the source tree, a "make clean"
|
|
is a good thing. If it isn't successful, don't worry about it,
|
|
it probably means the source directory is very clean.
|
|
[Richard Levitte]
|
|
|
|
*) Make sure any ENGINE control commands make local copies of string
|
|
pointers passed to them whenever necessary. Otherwise it is possible
|
|
the caller may have overwritten (or deallocated) the original string
|
|
data when a later ENGINE operation tries to use the stored values.
|
|
[Götz Babin-Ebell <babinebell@trustcenter.de>]
|
|
|
|
*) Improve diagnostics in file reading and command-line digests.
|
|
[Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>]
|
|
|
|
*) Add AES modes CFB and OFB to the object database. Correct an
|
|
error in AES-CFB decryption.
|
|
[Richard Levitte]
|
|
|
|
*) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
|
|
allows existing EVP_CIPHER_CTX structures to be reused after
|
|
calling EVP_*Final(). This behaviour is used by encryption
|
|
BIOs and some applications. This has the side effect that
|
|
applications must explicitly clean up cipher contexts with
|
|
EVP_CIPHER_CTX_cleanup() or they will leak memory.
|
|
[Steve Henson]
|
|
|
|
*) Check the values of dna and dnb in bn_mul_recursive before calling
|
|
bn_mul_comba (a non zero value means the a or b arrays do not contain
|
|
n2 elements) and fallback to bn_mul_normal if either is not zero.
|
|
[Steve Henson]
|
|
|
|
*) Fix escaping of non-ASCII characters when using the -subj option
|
|
of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
|
|
[Lutz Jaenicke]
|
|
|
|
*) Make object definitions compliant to LDAP (RFC2256): SN is the short
|
|
form for "surname", serialNumber has no short form.
|
|
Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
|
|
therefore remove "mail" short name for "internet 7".
|
|
The OID for unique identifiers in X509 certificates is
|
|
x500UniqueIdentifier, not uniqueIdentifier.
|
|
Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>)
|
|
[Lutz Jaenicke]
|
|
|
|
*) Add an "init" command to the ENGINE config module and auto initialize
|
|
ENGINEs. Without any "init" command the ENGINE will be initialized
|
|
after all ctrl commands have been executed on it. If init=1 the
|
|
ENGINE is initialized at that point (ctrls before that point are run
|
|
on the uninitialized ENGINE and after on the initialized one). If
|
|
init=0 then the ENGINE will not be initialized at all.
|
|
[Steve Henson]
|
|
|
|
*) Fix the 'app_verify_callback' interface so that the user-defined
|
|
argument is actually passed to the callback: In the
|
|
SSL_CTX_set_cert_verify_callback() prototype, the callback
|
|
declaration has been changed from
|
|
int (*cb)()
|
|
into
|
|
int (*cb)(X509_STORE_CTX *,void *);
|
|
in ssl_verify_cert_chain (ssl/ssl_cert.c), the call
|
|
i=s->ctx->app_verify_callback(&ctx)
|
|
has been changed into
|
|
i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg).
|
|
|
|
To update applications using SSL_CTX_set_cert_verify_callback(),
|
|
a dummy argument can be added to their callback functions.
|
|
[D. K. Smetters <smetters@parc.xerox.com>]

|
*) Added the '4758cca' ENGINE to support IBM 4758 cards.
|
|
[Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe]
|
|
|
|
*) Add and OPENSSL_LOAD_CONF define which will cause
|
|
OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
|
|
This allows older applications to transparently support certain
|
|
OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.
|
|
Two new functions OPENSSL_add_all_algorithms_noconf() which will never
|
|
load the config file and OPENSSL_add_all_algorithms_conf() which will
|
|
always load it have also been added.
|
|
[Steve Henson]
|
|
|
|
*) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
|
|
Adjust NIDs and EVP layer.
|
|
[Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
|
|
|
|
*) Config modules support in openssl utility.
|
|
|
|
Most commands now load modules from the config file,
|
|
though in a few (such as version) this isn't done
|
|
because it couldn't be used for anything.
|
|
|
|
In the case of ca and req the config file used is
|
|
the same as the utility itself: that is the -config
|
|
command line option can be used to specify an
|
|
alternative file.
|
|
[Steve Henson]
|
|
|
|
*) Move default behaviour from OPENSSL_config(). If appname is NULL
|
|
use "openssl_conf" if filename is NULL use default openssl config file.
|
|
[Steve Henson]
|
|
|
|
*) Add an argument to OPENSSL_config() to allow the use of an alternative
|
|
config section name. Add a new flag to tolerate a missing config file
|
|
and move code to CONF_modules_load_file().
|
|
[Steve Henson]
|
|
|
|
*) Support for crypto accelerator cards from Accelerated Encryption
|
|
Processing, www.aep.ie. (Use engine 'aep')
|
|
The support was copied from 0.9.6c [engine] and adapted/corrected
|
|
to work with the new engine framework.
|
|
[AEP Inc. and Richard Levitte]
|
|
|
|
*) Support for SureWare crypto accelerator cards from Baltimore
|
|
Technologies. (Use engine 'sureware')
|
|
The support was copied from 0.9.6c [engine] and adapted
|
|
to work with the new engine framework.
|
|
[Richard Levitte]
|
|
|
|
*) Have the CHIL engine fork-safe (as defined by nCipher) and actually
|
|
make the newer ENGINE framework commands for the CHIL engine work.
|
|
[Toomas Kiisk <vix@cyber.ee> and Richard Levitte]
|

|
*) Make it possible to produce shared libraries on ReliantUNIX.
|
|
[Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte]
|
|
|
|
*) Add the configuration target debug-linux-ppro.
|
|
Make 'openssl rsa' use the general key loading routines
|
|
implemented in apps.c, and make those routines able to
|
|
handle the key format FORMAT_NETSCAPE and the variant
|
|
FORMAT_IISSGC.

|
|
*) Add -keyform to rsautl, and document -engine.
|
|
[Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>]
|
|
|
|
*) Change BIO_new_file (crypto/bio/bss_file.c) to use new
|
|
BIO_R_NO_SUCH_FILE error code rather than the generic
|
|
ERR_R_SYS_LIB error code if fopen() fails with ENOENT.
|
|
[Ben Laurie]
|
|
|
|
*) Add new functions
|
|
ERR_peek_last_error
|
|
ERR_peek_last_error_line
|
|
ERR_peek_last_error_line_data.
|
|
These are similar to
|
|
ERR_peek_error
|
|
ERR_peek_error_line
|
|
ERR_peek_error_line_data,
|
|
but report on the latest error recorded rather than the first one
|
|
still in the error queue.
|
|
[Ben Laurie, Bodo Moeller]
|
|
|
|
*) default_algorithms option in ENGINE config module. This allows things
|
|
like:
|
|
default_algorithms = ALL
|
|
default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS
|
|
[Steve Henson]
|
|
|
|
*) Preliminary ENGINE config module.
|
|
[Steve Henson]
|
|
|
|
*) New experimental application configuration code.
|
|
[Steve Henson]
|
|
|
|
*) Change the AES code to follow the same name structure as all other
|
|
symmetric ciphers, and behave the same way. Move everything to
|
|
the directory crypto/aes, thereby obsoleting crypto/rijndael.
|
|
[Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
|
|
|
|
*) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c.
|
|
[Ben Laurie and Theo de Raadt]
|
|
|
|
*) Add option to output public keys in req command.
|
|
[Massimiliano Pala madwolf@openca.org]
|
|
|
|
*) Use wNAFs in EC_POINTs_mul() for improved efficiency
|
|
(up to about 10% better than before for P-192 and P-224).
|
|
[Bodo Moeller]
|
|
|
|
*) New functions/macros
|
|
|
|
SSL_CTX_set_msg_callback(ctx, cb)
|
|
SSL_CTX_set_msg_callback_arg(ctx, arg)
|
|
SSL_set_msg_callback(ssl, cb)
|
|
SSL_set_msg_callback_arg(ssl, arg)
|
|
|
|
to request calling a callback function
|
|
|
|
void cb(int write_p, int version, int content_type,
|
|
const void *buf, size_t len, SSL *ssl, void *arg)
|
|
|
|
whenever a protocol message has been completely received
|
|
(write_p == 0) or sent (write_p == 1). Here 'version' is the
|
|
protocol version according to which the SSL library interprets
|
|
the current protocol message (SSL2_VERSION, SSL3_VERSION, or
|
|
TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or
|
|
the content type as defined in the SSL 3.0/TLS 1.0 protocol
|
|
specification (change_cipher_spec(20), alert(21), handshake(22)).
|
|
'buf' and 'len' point to the actual message, 'ssl' to the
|
|
SSL object, and 'arg' is the application-defined value set by
|
|
SSL[_CTX]_set_msg_callback_arg().
|
|
|
|
'openssl s_client' and 'openssl s_server' have new '-msg' options
|
|
to enable a callback that displays all protocol messages.
|
|
[Bodo Moeller]
|
|
|
|
*) Change the shared library support so shared libraries are built as
|
|
soon as the corresponding static library is finished, and thereby get
|
|
openssl and the test programs linked against the shared library.
|
|
This still only happens when the keyword "shard" has been given to
|
|
the configuration scripts.
|
|
|
|
NOTE: shared library support is still an experimental thing, and
|
|
backward binary compatibility is still not guaranteed.
|
|
["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte]
|
|
|
|
*) Add support for Subject Information Access extension.
|
|
[Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
|
|
|
|
*) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero
|
|
additional bytes when new memory had to be allocated, not just
|
|
when reusing an existing buffer.
|
|
[Bodo Moeller]
|
|
|
|
*) New command line and configuration option 'utf8' for the req command.
|
|
This allows field values to be specified as UTF8 strings.
|
|
[Steve Henson]
|
|
|
|
*) Add -multi and -mr options to "openssl speed" - giving multiple parallel
|
|
runs for the former and machine-readable output for the latter.
|
|
[Ben Laurie]
|
|
|
|
*) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion
|
|
of the e-mail address in the DN (i.e., it will go into a certificate
|
|
extension only). The new configuration file option 'email_in_dn = no'
|
|
has the same effect.
|
|
[Massimiliano Pala madwolf@openca.org]
|
|
|
|
*) Change all functions with names starting with des_ to be starting
|
|
with DES_ instead. Add wrappers that are compatible with libdes,
|
|
but are named _ossl_old_des_*. Finally, add macros that map the
|
|
des_* symbols to the corresponding _ossl_old_des_* if libdes
|
|
compatibility is desired. If OpenSSL 0.9.6c compatibility is
|
|
desired, the des_* symbols will be mapped to DES_*, with one
|
|
exception.
|
|
|
|
Since we provide two compatibility mappings, the user needs to
|
|
define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes
|
|
compatibility is desired. The default (i.e., when that macro
|
|
isn't defined) is OpenSSL 0.9.6c compatibility.
|
|
|
|
There are also macros that enable and disable the support of old
|
|
des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT
|
|
and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those
|
|
are defined, the default will apply: to support the old des routines.
|
|
|
|
In either case, one must include openssl/des.h to get the correct
|
|
definitions. Do not try to just include openssl/des_old.h, that
|
|
won't work.
|
|
|
|
NOTE: This is a major break of an old API into a new one. Software
|
|
authors are encouraged to switch to the DES_ style functions. Some
|
|
time in the future, des_old.h and the libdes compatibility functions
|
|
will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the
|
|
default), and then completely removed.

*) Test for certificates which contain unsupported critical extensions.
|
|
If such a certificate is found during a verify operation it is
|
|
rejected by default: this behaviour can be overridden by either
|
|
handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
|
|
by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
|
|
X509_supported_extension() has also been added which returns 1 if a
|
|
particular extension is supported.
|
|
[Steve Henson]
|
|
|
|
*) Modify the behaviour of EVP cipher functions in similar way to digests
|
|
to retain compatibility with existing code.
|
|
[Steve Henson]
|
|
|
|
*) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain
|
|
compatibility with existing code. In particular the 'ctx' parameter does
|
|
not have to be to be initialized before the call to EVP_DigestInit() and
|
|
it is tidied up after a call to EVP_DigestFinal(). New function
|
|
EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
|
|
EVP_MD_CTX_copy() changed to not require the destination to be
|
|
initialized valid and new function EVP_MD_CTX_copy_ex() added which
|
|
requires the destination to be valid.
|
|
|
|
Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
|
|
EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
|
|
[Steve Henson]
|
|
|
|
*) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
|
|
so that complete 'Handshake' protocol structures are kept in memory
|
|
instead of overwriting 'msg_type' and 'length' with 'body' data.
|
|
[Bodo Moeller]
|
|
|
|
*) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
|
|
[Massimo Santin via Richard Levitte]
|
|
|
|
*) Major restructuring to the underlying ENGINE code. This includes
|
|
reduction of linker bloat, separation of pure "ENGINE" manipulation
|
|
(initialisation, etc) from functionality dealing with implementations
|
|
of specific crypto interfaces. This change also introduces integrated
|
|
support for symmetric ciphers and digest implementations - so ENGINEs
|
|
can now accelerate these by providing EVP_CIPHER and EVP_MD
|
|
implementations of their own. This is detailed in crypto/engine/README
|
|
as it couldn't be adequately described here. However, there are a few
|
|
API changes worth noting - some RSA, DSA, DH, and RAND functions that
|
|
were changed in the original introduction of ENGINE code have now
|
|
reverted back - the hooking from this code to ENGINE is now a good
|
|
deal more passive and at run-time, operations deal directly with
|
|
RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
|
|
dereferencing through an ENGINE pointer any more. Also, the ENGINE
|
|
functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
|
|
they were not being used by the framework as there is no concept of a
|
|
BIGNUM_METHOD and they could not be generalised to the new
|
|
'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
|
|
ENGINE_cpy() has been removed as it cannot be consistently defined in
|
|
the new code.
|
|
[Geoff Thorpe]
|
|
|
|
*) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
|
|
[Steve Henson]
|
|
|
|
*) Change mkdef.pl to sort symbols that get the same entry number,
|
|
and make sure the automatically generated functions ERR_load_*
|
|
become part of libeay.num as well.
|
|
[Richard Levitte]
|
|
|
|
*) New function SSL_renegotiate_pending(). This returns true once
|
|
renegotiation has been requested (either SSL_renegotiate() call
|
|
or HelloRequest/ClientHello received from the peer) and becomes
|
|
false once a handshake has been completed.
|
|
(For servers, SSL_renegotiate() followed by SSL_do_handshake()
|
|
sends a HelloRequest, but does not ensure that a handshake takes
|
|
place. SSL_renegotiate_pending() is useful for checking if the
|
|
client has followed the request.)
|
|
[Bodo Moeller]
|
|
|
|
*) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
|
|
By default, clients may request session resumption even during
|
|
renegotiation (if session ID contexts permit); with this option,
|
|
session resumption is possible only in the first handshake.
|
|
|
|
SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes
|
|
more bits available for options that should not be part of
|
|
SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION).
|
|
[Bodo Moeller]
|
|
|
|
*) Add some demos for certificate and certificate request creation.
|
|
[Steve Henson]
|
|
|
|
*) Make maximum certificate chain size accepted from the peer application
|
|
settable (SSL*_get/set_max_cert_list()), as proposed by
|
|
"Douglas E. Engert" <deengert@anl.gov>.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Add support for shared libraries for Unixware-7
|
|
(Boyd Lynn Gerber <gerberb@zenez.com>).
|
|
[Lutz Jaenicke]
|
|
|
|
*) Add a "destroy" handler to ENGINEs that allows structural cleanup to
|
|
be done prior to destruction. Use this to unload error strings from
|
|
ENGINEs that load their own error strings. NB: This adds two new API
|
|
functions to "get" and "set" this destroy handler in an ENGINE.
|
|
[Geoff Thorpe]
|
|
|
|
*) Alter all existing ENGINE implementations (except "openssl" and
|
|
"openbsd") to dynamically instantiate their own error strings. This
|
|
makes them more flexible to be built both as statically-linked ENGINEs
|
|
and self-contained shared-libraries loadable via the "dynamic" ENGINE.
|
|
Also, add stub code to each that makes building them as self-contained
|
|
shared-libraries easier (see README.ENGINE).
|
|
[Geoff Thorpe]
|
|
|
|
*) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
|
|
implementations into applications that are completely implemented in
|
|
self-contained shared-libraries. The "dynamic" ENGINE exposes control
|
|
commands that can be used to configure what shared-library to load and
|
|
to control aspects of the way it is handled. Also, made an update to
|
|
the README.ENGINE file that brings its information up-to-date and
|
|
provides some information and instructions on the "dynamic" ENGINE
|
|
(ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
|
|
[Geoff Thorpe]
|
|
|
|
*) Make it possible to unload ranges of ERR strings with a new
|
|
"ERR_unload_strings" function.
|
|
[Geoff Thorpe]
|
|
|
|
*) Add a copy() function to EVP_MD.
|
|
[Ben Laurie]
|
|
|
|
*) Make EVP_MD routines take a context pointer instead of just the
|
|
md_data void pointer.
|
|
[Ben Laurie]
|
|
|
|
*) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
|
|
that the digest can only process a single chunk of data
|
|
(typically because it is provided by a piece of
|
|
hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
|
|
is only going to provide a single chunk of data, and hence the
|
|
framework needn't accumulate the data for oneshot drivers.
|
|
[Ben Laurie]
|
|
|
|
*) As with "ERR", make it possible to replace the underlying "ex_data"
|
|
functions. This change also alters the storage and management of global
|
|
ex_data state - it's now all inside ex_data.c and all "class" code (eg.
|
|
RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
|
|
index counters. The API functions that use this state have been changed
|
|
to take a "class_index" rather than pointers to the class's local STACK
|
|
and counter, and there is now an API function to dynamically create new
|
|
classes. This centralisation allows us to (a) plug a lot of the
|
|
thread-safety problems that existed, and (b) makes it possible to clean
|
|
up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
|
|
such data would previously have always leaked in application code and
|
|
workarounds were in place to make the memory debugging turn a blind eye
|
|
to it. Application code that doesn't use this new function will still
|
|
leak as before, but their memory debugging output will announce it now
|
|
rather than letting it slide.
|
|
|
|
Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
|
|
induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
|
|
has a return value to indicate success or failure.
|
|
[Geoff Thorpe]
|
|
|
|
*) Make it possible to replace the underlying "ERR" functions such that the
|
|
global state (2 LHASH tables and 2 locks) is only used by the "default"
|
|
implementation. This change also adds two functions to "get" and "set"
|
|
the implementation prior to it being automatically set the first time
|
|
any other ERR function takes place. Ie. an application can call "get",
|
|
pass the return value to a module it has just loaded, and that module
|
|
can call its own "set" function using that value. This means the
|
|
module's "ERR" operations will use (and modify) the error state in the
|
|
application and not in its own statically linked copy of OpenSSL code.
|
|
[Geoff Thorpe]
|
|
|
|
*) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
|
|
reference counts. This performs normal REF_PRINT/REF_CHECK macros on
|
|
the operation, and provides a more encapsulated way for external code
|
|
(crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
|
|
to use these functions rather than manually incrementing the counts.
|
|
|
|
Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
|
|
[Geoff Thorpe]
|
|
|
|
*) Add EVP test program.
|
|
[Ben Laurie]
|
|
|
|
*) Add symmetric cipher support to ENGINE. Expect the API to change!
|
|
[Ben Laurie]
|
|
|
|
*) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
|
|
X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
|
|
X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
|
|
These allow a CRL to be built without having to access X509_CRL fields
|
|
directly. Modify 'ca' application to use new functions.
|
|
[Steve Henson]
|
|
|
|
*) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
|
|
bug workarounds. Rollback attack detection is a security feature.
|
|
The problem will only arise on OpenSSL servers when TLSv1 is not
|
|
available (sslv3_server_method() or SSL_OP_NO_TLSv1).
|
|
Software authors not wanting to support TLSv1 will have special reasons
|
|
for their choice and can explicitly enable this option.
|
|
[Bodo Moeller, Lutz Jaenicke]
|
|
|
|
*) Rationalise EVP so it can be extended: don't include a union of
|
|
cipher/digest structures, add init/cleanup functions for EVP_MD_CTX
|
|
(similar to those existing for EVP_CIPHER_CTX).
|
|
Usage example:
|
|
|
|
EVP_MD_CTX md;
|
|
|
|
EVP_MD_CTX_init(&md); /* new function call */
|
|
EVP_DigestInit(&md, EVP_sha1());
|
|
EVP_DigestUpdate(&md, in, len);
|
|
EVP_DigestFinal(&md, out, NULL);
|
|
EVP_MD_CTX_cleanup(&md); /* new function call */
|
|
|
|
[Ben Laurie]
|
|
|
|
*) Make DES key schedule conform to the usual scheme, as well as
|
|
correcting its structure. This means that calls to DES functions
|
|
now have to pass a pointer to a des_key_schedule instead of a
|
|
plain des_key_schedule (which was actually always a pointer
|
|
anyway): E.g.,
|
|
|
|
des_key_schedule ks;
|
|
|
|
des_set_key_checked(..., &ks);
|
|
des_ncbc_encrypt(..., &ks, ...);
|
|
|
|
(Note that a later change renames 'des_...' into 'DES_...'.)
|
|
[Ben Laurie]
|
|
|
|
*) Initial reduction of linker bloat: the use of some functions, such as
|
|
PEM causes large amounts of unused functions to be linked in due to
|
|
poor organisation. For example pem_all.c contains every PEM function
|
|
which has a knock on effect of linking in large amounts of (unused)
|
|
ASN1 code. Grouping together similar functions and splitting unrelated
|
|
functions prevents this.
|
|
[Steve Henson]
|
|
|
|
*) Cleanup of EVP macros.
|
|
[Ben Laurie]
|
|
|
|
*) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
|
|
correct _ecb suffix.
|
|
[Ben Laurie]
|
|
|
|
*) Add initial OCSP responder support to ocsp application. The
|
|
revocation information is handled using the text based index
|
|
use by the ca application. The responder can either handle
|
|
requests generated internally, supplied in files (for example
|
|
via a CGI script) or using an internal minimal server.
|
|
[Steve Henson]
|
|
|
|
*) Add configuration choices to get zlib compression for TLS.
|
|
[Richard Levitte]
|
|
|
|
*) Changes to Kerberos SSL for RFC 2712 compliance:
|
|
1. Implemented real KerberosWrapper, instead of just using
|
|
KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
|
|
2. Implemented optional authenticator field of KerberosWrapper.
|
|
|
|
Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
|
|
and authenticator structs; see crypto/krb5/.
|
|
|
|
Generalized Kerberos calls to support multiple Kerberos libraries.

[Vern Staats <staatsvr@asc.hpc.mil>,

|
|
via Richard Levitte]
|
|
|
|
*) Cause 'openssl speed' to use fully hard-coded DSA keys as it
|
|
already does with RSA. testdsa.h now has 'priv_key/pub_key'
|
|
values for each of the key sizes rather than having just
|
|
parameters (and 'speed' generating keys each time).
|
|
[Geoff Thorpe]
|
|
|
|
*) Speed up EVP routines.

[Ben Laurie]
|
|
|
|
*) Added the OS2-EMX target.
|
|
["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
|
|
|
|
*) Rewrite apps to use NCONF routines instead of the old CONF. New functions
|
|
to support NCONF routines in extension code. New function CONF_set_nconf()
|
|
to allow functions which take an NCONF to also handle the old LHASH
|
|
structure: this means that the old CONF compatible routines can be
|
|
retained (in particular wrt extensions) without having to duplicate the
|
|
code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
|
|
[Steve Henson]
|
|
|
|
*) Enhance the general user interface with mechanisms for inner control
|
|
and with possibilities to have yes/no kind of prompts.
|
|
[Richard Levitte]
|
|
|
|
*) Change all calls to low level digest routines in the library and
|
|
applications to use EVP. Add missing calls to HMAC_cleanup() and
|
|
don't assume HMAC_CTX can be copied using memcpy().
|
|
[Verdon Walker <VWalker@novell.com>, Steve Henson]
|
|
|
|
*) Add the possibility to control engines through control names but with
|
|
arbitrary arguments instead of just a string.
|
|
Change the key loaders to take a UI_METHOD instead of a callback
|
|
function pointer. NOTE: this breaks binary compatibility with earlier
|
|
versions of OpenSSL [engine].
|
|
Adapt the nCipher code for these new conditions and add a card insertion
|
|
callback.
|
|
[Richard Levitte]
|
|
|
|
*) Enhance the general user interface with mechanisms to better support
|
|
dialog box interfaces, application-defined prompts, the possibility
|
|
to use defaults (for example default passwords from somewhere else)
|
|
and interrupts/cancellations.
|
|
[Richard Levitte]
|
|
|
|
*) Tidy up PKCS#12 attribute handling. Add support for the CSP name
|
|
attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
|
|
[Steve Henson]
|
|
|
|
*) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
|
|
tidy up some unnecessarily weird code in 'sk_new()').
|
|
[Geoff, reported by Diego Tartara <dtartara@novamens.com>]
|
|
|
|
*) Change the key loading routines for ENGINEs to use the same kind
|
|
callback (pem_password_cb) as all other routines that need this
|
|
kind of callback.
|
|
[Richard Levitte]
|
|
|
|
*) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
|
|
256 bit (=32 byte) keys. Of course seeding with more entropy bytes
|
|
than this minimum value is recommended.
|
|
[Lutz Jaenicke]
|
|
|
|
*) New random seeder for OpenVMS, using the system process statistics
|
|
that are easily reachable.
|
|
[Richard Levitte]
|
|
|
|
*) Windows apparently can't transparently handle global
|
|
variables defined in DLLs. Initialisations such as:
|
|
|
|
const ASN1_ITEM *it = &ASN1_INTEGER_it;
|
|
|
|
won't compile. This is used by the any applications that need to
|
|
declare their own ASN1 modules. This was fixed by adding the option
|
|
EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
|
|
needed for static libraries under Win32.
|
|
[Steve Henson]
|
|
|
|
*) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
|
|
setting of purpose and trust fields. New X509_STORE trust and
|
|
purpose functions and tidy up setting in other SSL functions.
|
|
[Steve Henson]
|
|
|
|
*) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
|
|
structure. These are inherited by X509_STORE_CTX when it is
|
|
initialised. This allows various defaults to be set in the
|
|
X509_STORE structure (such as flags for CRL checking and custom
|
|
purpose or trust settings) for functions which only use X509_STORE_CTX
|
|
internally such as S/MIME.
|
|
|
|
Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
|
|
trust settings if they are not set in X509_STORE. This allows X509_STORE
|
|
purposes and trust (in S/MIME for example) to override any set by default.
|
|
|
|
Add command line options for CRL checking to smime, s_client and s_server
|
|
applications.
|
|
[Steve Henson]
|
|
|
|
*) Initial CRL based revocation checking. If the CRL checking flag(s)
|
|
are set then the CRL is looked up in the X509_STORE structure and
|
|
its validity and signature checked, then if the certificate is found
|
|
in the CRL the verify fails with a revoked error.
|
|
|
|
Various new CRL related callbacks added to X509_STORE_CTX structure.
|
|
|
|
Command line options added to 'verify' application to support this.
|
|
|
|
This needs some additional work, such as being able to handle multiple
|
|
CRLs with different times, extension based lookup (rather than just
|
|
by subject name) and ultimately more complete V2 CRL extension
|
|
handling.
|
|
[Steve Henson]
|
|
|
|
*) Add a general user interface API (crypto/ui/). This is designed
|
|
to replace things like des_read_password and friends (backward
|
|
compatibility functions using this new API are provided).
|
|
The purpose is to remove prompting functions from the DES code
|
|
section as well as provide for prompting through dialog boxes in
|
|
a window system and the like.
|
|
[Richard Levitte]
|
|
|
|
*) Add "ex_data" support to ENGINE so implementations can add state at a
|
|
per-structure level rather than having to store it globally.
|
|
[Geoff]
|
|
|
|
*) Make it possible for ENGINE structures to be copied when retrieved by
|
|
ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
|
|
This causes the "original" ENGINE structure to act like a template,
|
|
analogous to the RSA vs. RSA_METHOD type of separation. Because of this
|
|
operational state can be localised to each ENGINE structure, despite the
|
|
fact they all share the same "methods". New ENGINE structures returned in
|
|
this case have no functional references and the return value is the single
|
|
structural reference. This matches the single structural reference returned
|
|
by ENGINE_by_id() normally, when it is incremented on the pre-existing
|
|
ENGINE structure.
|
|
[Geoff]
|
|
|
|
*) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
|
|
needs to match any other type at all we need to manually clear the
|
|
tag cache.
|
|
[Steve Henson]
|
|
|
|
*) Changes to the "openssl engine" utility to include;
|
|
- verbosity levels ('-v', '-vv', and '-vvv') that provide information
|
|
about an ENGINE's available control commands.
|
|
- executing control commands from command line arguments using the
|
|
'-pre' and '-post' switches. '-post' is only used if '-t' is
|
|
specified and the ENGINE is successfully initialised. The syntax for
|
|
the individual commands are colon-separated, for example;
|
|
openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
|
|
[Geoff]
|
|
|
|
*) New dynamic control command support for ENGINEs. ENGINEs can now
|
|
declare their own commands (numbers), names (strings), descriptions,
|
|
and input types for run-time discovery by calling applications. A
|
|
subset of these commands are implicitly classed as "executable"
|
|
depending on their input type, and only these can be invoked through
|
|
the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
|
|
can be based on user input, config files, etc). The distinction is
|
|
that "executable" commands cannot return anything other than a boolean
|
|
result and can only support numeric or string input, whereas some
|
|
discoverable commands may only be for direct use through
|
|
ENGINE_ctrl(), eg. supporting the exchange of binary data, function
|
|
pointers, or other custom uses. The "executable" commands are to
|
|
support parameterisations of ENGINE behaviour that can be
|
|
unambiguously defined by ENGINEs and used consistently across any
|
|
OpenSSL-based application. Commands have been added to all the
|
|
existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
|
|
control over shared-library paths without source code alterations.
|
|
[Geoff]
|
|
|
|
*) Changed all ENGINE implementations to dynamically allocate their
|
|
ENGINEs rather than declaring them statically. Apart from this being
|
|
necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
|
|
this also allows the implementations to compile without using the
|
|
internal engine_int.h header.
|
|
[Geoff]
|
|
|
|
*) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
|
|
'const' value. Any code that should be able to modify a RAND_METHOD
|
|
should already have non-const pointers to it (ie. they should only
|
|
modify their own ones).
|
|
[Geoff]
|
|
|
|
*) Made a variety of little tweaks to the ENGINE code.
|
|
- "atalla" and "ubsec" string definitions were moved from header files
|
|
to C code. "nuron" string definitions were placed in variables
|
|
rather than hard-coded - allowing parameterisation of these values
|
|
later on via ctrl() commands.
|
|
- Removed unused "#if 0"'d code.
|
|
- Fixed engine list iteration code so it uses ENGINE_free() to release
|
|
structural references.
|
|
- Constified the RAND_METHOD element of ENGINE structures.
|
|
- Constified various get/set functions as appropriate and added
|
|
missing functions (including a catch-all ENGINE_cpy that duplicates
|
|
all ENGINE values onto a new ENGINE except reference counts/state).
|
|
- Removed NULL parameter checks in get/set functions. Setting a method
|
|
or function to NULL is a way of cancelling out a previously set
|
|
value. Passing a NULL ENGINE parameter is just plain stupid anyway
|
|
and doesn't justify the extra error symbols and code.
|
|
- Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
|
|
flags from engine_int.h to engine.h.
|
|
- Changed prototypes for ENGINE handler functions (init(), finish(),
|
|
ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
|
|
[Geoff]
|
|
|
|
*) Implement binary inversion algorithm for BN_mod_inverse in addition
|
|
to the algorithm using long division. The binary algorithm can be
|
|
used only if the modulus is odd. On 32-bit systems, it is faster
|
|
only for relatively small moduli (roughly 20-30% for 128-bit moduli,
|
|
roughly 5-15% for 256-bit moduli), so we use it only for moduli
|
|
up to 450 bits. In 64-bit environments, the binary algorithm
|
|
appears to be advantageous for much longer moduli; here we use it
|
|
for moduli up to 2048 bits.
|
|
[Bodo Moeller]
|
|
|
|
*) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
|
|
could not support the combine flag in choice fields.
|
|
[Steve Henson]
|
|
|
|
*) Add a 'copy_extensions' option to the 'ca' utility. This copies
|
|
extensions from a certificate request to the certificate.
|
|
[Steve Henson]
|
|
|
|
*) Allow multiple 'certopt' and 'nameopt' options to be separated
|
|
by commas. Add 'namopt' and 'certopt' options to the 'ca' config
|
|
file: this allows the display of the certificate about to be
|
|
signed to be customised, to allow certain fields to be included
|
|
or excluded and extension details. The old system didn't display
|
|
multicharacter strings properly, omitted fields not in the policy
|
|
and couldn't display additional details such as extensions.
|
|
[Steve Henson]
|
|
|
|
*) Function EC_POINTs_mul for multiple scalar multiplication
|
|
of an arbitrary number of elliptic curve points
|
|
\sum scalars[i]*points[i],
|
|
optionally including the generator defined for the EC_GROUP:
|
|
scalar*generator + \sum scalars[i]*points[i].
|
|
|
|
EC_POINT_mul is a simple wrapper function for the typical case
|
|
that the point list has just one item (besides the optional
|
|
generator).
|
|
[Bodo Moeller]
|
|
|
|
*) First EC_METHODs for curves over GF(p):
|
|
|
|
EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
|
|
operations and provides various method functions that can also
|
|
operate with faster implementations of modular arithmetic.
|
|
|
|
EC_GFp_mont_method() reuses most functions that are part of
|
|
EC_GFp_simple_method, but uses Montgomery arithmetic.
|
|
|
|
[Bodo Moeller; point addition and point doubling
|
|
implementation directly derived from source code provided by
|
|
Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
|
|
|
|
*) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
|
|
crypto/ec/ec_lib.c):
|
|
|
|
Curves are EC_GROUP objects (with an optional group generator)
|
|
based on EC_METHODs that are built into the library.
|
|
|
|
Points are EC_POINT objects based on EC_GROUP objects.
|
|
|
|
Most of the framework would be able to handle curves over arbitrary
|
|
finite fields, but as there are no obvious types for fields other
|
|
than GF(p), some functions are limited to that for now.
|
|
[Bodo Moeller]
|
|
|
|
*) Add the -HTTP option to s_server. It is similar to -WWW, but requires
|
|
that the file contains a complete HTTP response.
|
|
[Richard Levitte]
|
|
|
|
*) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
|
|
change the def and num file printf format specifier from "%-40sXXX"
|
|
to "%-39s XXX". The latter will always guarantee a space after the
|
|
field while the former will cause them to run together if the field
|
|
is 40 of more characters long.
|
|
[Steve Henson]
|
|
|
|
*) Constify the cipher and digest 'method' functions and structures
|
|
and modify related functions to take constant EVP_MD and EVP_CIPHER
|
|
pointers.
|
|
[Steve Henson]
|
|
|
|
*) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
|
|
in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
|
|
[Bodo Moeller]
|
|
|
|
*) Modify EVP_Digest*() routines so they now return values. Although the
|
|
internal software routines can never fail additional hardware versions
|
|
might.
|
|
[Steve Henson]
|
|
|
|
*) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
|
|
|
|
Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
|
|
(= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
|
|
|
|
ASN1 error codes
|
|
ERR_R_NESTED_ASN1_ERROR
|
|
...
|
|
ERR_R_MISSING_ASN1_EOS
|
|
were 4 .. 9, conflicting with
|
|
ERR_LIB_RSA (= ERR_R_RSA_LIB)
|
|
...
|
|
ERR_LIB_PEM (= ERR_R_PEM_LIB).
|
|
They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
|
|
|
|
Add new error code 'ERR_R_INTERNAL_ERROR'.
|
|
[Bodo Moeller]
|
|
|
|
*) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
|
|
suffices.
|
|
[Bodo Moeller]
|
|
|
|
*) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
|
|
sets the subject name for a new request or supersedes the
|
|
subject name in a given request. Formats that can be parsed are
|
|
'CN=Some Name, OU=myOU, C=IT'
|
|
and
|
|
'CN=Some Name/OU=myOU/C=IT'.
|
|
|
|
Add options '-batch' and '-verbose' to 'openssl req'.
|
|
[Massimiliano Pala <madwolf@hackmasters.net>]
|
|
|
|
*) Introduce the possibility to access global variables through
|
|
functions on platform were that's the best way to handle exporting
|
|
global variables in shared libraries. To enable this functionality,
|
|
one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
|
|
"OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
|
|
is normally done by Configure or something similar).
|
|
|
|
To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
|
|
in the source file (foo.c) like this:
|
|
|
|
OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
|
|
OPENSSL_IMPLEMENT_GLOBAL(double,bar);
|
|
|
|
To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
|
|
and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
|
|
|
|
OPENSSL_DECLARE_GLOBAL(int,foo);
|
|
#define foo OPENSSL_GLOBAL_REF(foo)
|
|
OPENSSL_DECLARE_GLOBAL(double,bar);
|
|
#define bar OPENSSL_GLOBAL_REF(bar)
|
|
|
|
The #defines are very important, and therefore so is including the
|
|
header file everywhere where the defined globals are used.
|
|
|
|
The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
|
|
of ASN.1 items, but that structure is a bit different.
|
|
|
|
The largest change is in util/mkdef.pl which has been enhanced with
|
|
better and easier to understand logic to choose which symbols should
|
|
go into the Windows .def files as well as a number of fixes and code
|
|
cleanup (among others, algorithm keywords are now sorted
|
|
lexicographically to avoid constant rewrites).
|
|
[Richard Levitte]
|
|
|
|
*) In BN_div() keep a copy of the sign of 'num' before writing the
|
|
result to 'rm' because if rm==num the value will be overwritten
|
|
and produce the wrong result if 'num' is negative: this caused
|
|
problems with BN_mod() and BN_nnmod().
|
|
[Steve Henson]
|
|
|
|
*) Function OCSP_request_verify(). This checks the signature on an
|
|
OCSP request and verifies the signer certificate. The signer
|
|
certificate is just checked for a generic purpose and OCSP request
|
|
trust settings.
|
|
[Steve Henson]
|
|
|
|
*) Add OCSP_check_validity() function to check the validity of OCSP
|
|
responses. OCSP responses are prepared in real time and may only
|
|
be a few seconds old. Simply checking that the current time lies
|
|
between thisUpdate and nextUpdate max reject otherwise valid responses
|
|
caused by either OCSP responder or client clock inaccuracy. Instead
|
|
we allow thisUpdate and nextUpdate to fall within a certain period of
|
|
the current time. The age of the response can also optionally be
|
|
checked. Two new options -validity_period and -status_age added to
|
|
ocsp utility.
|
|
[Steve Henson]
|
|
|
|
*) If signature or public key algorithm is unrecognized print out its
|
|
OID rather that just UNKNOWN.
|
|
[Steve Henson]
|
|
|
|
*) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
|
|
OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
|
|
ID to be generated from the issuer certificate alone which can then be
|
|
passed to OCSP_id_issuer_cmp().
|
|
[Steve Henson]
|
|
|
|
*) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
|
|
ASN1 modules to export functions returning ASN1_ITEM pointers
|
|
instead of the ASN1_ITEM structures themselves. This adds several
|
|
new macros which allow the underlying ASN1 function/structure to
|
|
be accessed transparently. As a result code should not use ASN1_ITEM
|
|
references directly (such as &X509_it) but instead use the relevant
|
|
macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
|
|
use of the new ASN1 code on platforms where exporting structures
|
|
is problematical (for example in shared libraries) but exporting
|
|
functions returning pointers to structures is not.
|
|
[Steve Henson]
|
|
|
|
*) Add support for overriding the generation of SSL/TLS session IDs.
|
|
These callbacks can be registered either in an SSL_CTX or per SSL.
|
|
The purpose of this is to allow applications to control, if they wish,
|
|
the arbitrary values chosen for use as session IDs, particularly as it
|
|
can be useful for session caching in multiple-server environments. A
|
|
command-line switch for testing this (and any client code that wishes
|
|
to use such a feature) has been added to "s_server".
|
|
[Geoff Thorpe, Lutz Jaenicke]
|
|
|
|
*) Modify mkdef.pl to recognise and parse preprocessor conditionals
|
|
of the form '#if defined(...) || defined(...) || ...' and
|
|
'#if !defined(...) && !defined(...) && ...'. This also avoids
|
|
the growing number of special cases it was previously handling.
|
|
[Richard Levitte]
|
|
|
|
*) Make all configuration macros available for application by making
|
|
sure they are available in opensslconf.h, by giving them names starting
|
|
with "OPENSSL_" to avoid conflicts with other packages and by making
|
|
sure e_os2.h will cover all platform-specific cases together with
|
|
opensslconf.h.
|
|
Additionally, it is now possible to define configuration/platform-
|
|
specific names (called "system identities"). In the C code, these
|
|
are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
|
|
macro with the name beginning with "OPENSSL_SYS_", which is determined
|
|
from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
|
|
what is available.
|
|
[Richard Levitte]
|
|
|
|
*) New option -set_serial to 'req' and 'x509' this allows the serial
|
|
number to use to be specified on the command line. Previously self
|
|
signed certificates were hard coded with serial number 0 and the
|
|
CA options of 'x509' had to use a serial number in a file which was
|
|
auto incremented.
|
|
[Steve Henson]
|
|
|
|
*) New options to 'ca' utility to support V2 CRL entry extensions.
|
|
Currently CRL reason, invalidity date and hold instruction are
|
|
supported. Add new CRL extensions to V3 code and some new objects.
|
|
[Steve Henson]
|
|
|
|
*) New function EVP_CIPHER_CTX_set_padding() this is used to
|
|
disable standard block padding (aka PKCS#5 padding) in the EVP
|
|
API, which was previously mandatory. This means that the data is
|
|
not padded in any way and so the total length much be a multiple
|
|
of the block size, otherwise an error occurs.
|
|
[Steve Henson]
|
|
|
|
*) Initial (incomplete) OCSP SSL support.
|
|
[Steve Henson]
|
|
|
|
*) New function OCSP_parse_url(). This splits up a URL into its host,
|
|
port and path components: primarily to parse OCSP URLs. New -url
|
|
option to ocsp utility.
|
|
[Steve Henson]
|
|
|
|
*) New nonce behavior. The return value of OCSP_check_nonce() now
|
|
reflects the various checks performed. Applications can decide
|
|
whether to tolerate certain situations such as an absent nonce
|
|
in a response when one was present in a request: the ocsp application
|
|
just prints out a warning. New function OCSP_add1_basic_nonce()
|
|
this is to allow responders to include a nonce in a response even if
|
|
the request is nonce-less.
|
|
[Steve Henson]
|
|
|
|
*) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
|
|
skipped when using openssl x509 multiple times on a single input file,
|
|
e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
|
|
[Bodo Moeller]
|
|
|
|
*) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
|
|
set string type: to handle setting ASN1_TIME structures. Fix ca
|
|
utility to correctly initialize revocation date of CRLs.
|
|
[Steve Henson]
|
|
|
|
*) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
|
|
the clients preferred ciphersuites and rather use its own preferences.
|
|
Should help to work around M$ SGC (Server Gated Cryptography) bug in
|
|
Internet Explorer by ensuring unchanged hash method during stepup.
|
|
(Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
|
|
[Lutz Jaenicke]
|
|
|
|
*) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
|
|
to aes and add a new 'exist' option to print out symbols that don't
|
|
appear to exist.
|
|
[Steve Henson]
|
|
|
|
*) Additional options to ocsp utility to allow flags to be set and
|
|
additional certificates supplied.
|
|
[Steve Henson]
|
|
|
|
*) Add the option -VAfile to 'openssl ocsp', so the user can give the
|
|
OCSP client a number of certificate to only verify the response
|
|
signature against.
|
|
[Richard Levitte]
|
|
|
|
*) Update Rijndael code to version 3.0 and change EVP AES ciphers to
|
|
handle the new API. Currently only ECB, CBC modes supported. Add new
|
|
AES OIDs.
|
|
|
|
Add TLS AES ciphersuites as described in RFC3268, "Advanced
|
|
Encryption Standard (AES) Ciphersuites for Transport Layer
|
|
Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were
|
|
not enabled by default and were not part of the "ALL" ciphersuite
|
|
alias because they were not yet official; they could be
|
|
explicitly requested by specifying the "AESdraft" ciphersuite
|
|
group alias. In the final release of OpenSSL 0.9.7, the group
|
|
alias is called "AES" and is part of "ALL".)
|
|
[Ben Laurie, Steve Henson, Bodo Moeller]
|
|
|
|
*) New function OCSP_copy_nonce() to copy nonce value (if present) from
|
|
request to response.
|
|
[Steve Henson]
|
|
|
|
*) Functions for OCSP responders. OCSP_request_onereq_count(),
|
|
OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
|
|
extract information from a certificate request. OCSP_response_create()
|
|
creates a response and optionally adds a basic response structure.
|
|
OCSP_basic_add1_status() adds a complete single response to a basic
|
|
response and returns the OCSP_SINGLERESP structure just added (to allow
|
|
extensions to be included for example). OCSP_basic_add1_cert() adds a
|
|
certificate to a basic response and OCSP_basic_sign() signs a basic
|
|
response with various flags. New helper functions ASN1_TIME_check()
|
|
(checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
|
|
(converts ASN1_TIME to GeneralizedTime).
|
|
[Steve Henson]
|
|
|
|
*) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
|
|
in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
|
|
structure from a certificate. X509_pubkey_digest() digests the public_key
|
|
contents: this is used in various key identifiers.
|
|
[Steve Henson]
|
|
|
|
*) Make sk_sort() tolerate a NULL argument.
|
|
[Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
|
|
|
|
*) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
|
|
passed by the function are trusted implicitly. If any of them signed the
|
|
response then it is assumed to be valid and is not verified.
|
|
[Steve Henson]
|
|
|
|
*) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
|
|
to data. This was previously part of the PKCS7 ASN1 code. This
|
|
was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
|
|
[Steve Henson, reported by Kenneth R. Robinette
|
|
<support@securenetterm.com>]
|
|
|
|
*) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
|
|
routines: without these tracing memory leaks is very painful.
|
|
Fix leaks in PKCS12 and PKCS7 routines.
|
|
[Steve Henson]
|
|
|
|
*) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
|
|
Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
|
|
effectively meant GeneralizedTime would never be used. Now it
|
|
is initialised to -1 but X509_time_adj() now has to check the value
|
|
and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
|
|
V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
|
|
[Steve Henson, reported by Kenneth R. Robinette
|
|
<support@securenetterm.com>]
|
|
|
|
*) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
|
|
result in a zero length in the ASN1_INTEGER structure which was
|
|
not consistent with the structure when d2i_ASN1_INTEGER() was used
|
|
and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
|
|
to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
|
|
where it did not print out a minus for negative ASN1_INTEGER.
|
|
[Steve Henson]
|
|
|
|
*) Add summary printout to ocsp utility. The various functions which
|
|
convert status values to strings have been renamed to:
|
|
OCSP_response_status_str(), OCSP_cert_status_str() and
|
|
OCSP_crl_reason_str() and are no longer static. New options
|
|
to verify nonce values and to disable verification. OCSP response
|
|
printout format cleaned up.
|
|
[Steve Henson]
|
|
|
|
*) Add additional OCSP certificate checks. These are those specified
|
|
in RFC2560. This consists of two separate checks: the CA of the
|
|
certificate being checked must either be the OCSP signer certificate
|
|
or the issuer of the OCSP signer certificate. In the latter case the
|
|
OCSP signer certificate must contain the OCSP signing extended key
|
|
usage. This check is performed by attempting to match the OCSP
|
|
signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
|
|
in the OCSP_CERTID structures of the response.
|
|
[Steve Henson]
|
|
|
|
*) Initial OCSP certificate verification added to OCSP_basic_verify()
|
|
and related routines. This uses the standard OpenSSL certificate
|
|
verify routines to perform initial checks (just CA validity) and
|
|
to obtain the certificate chain. Then additional checks will be
|
|
performed on the chain. Currently the root CA is checked to see
|
|
if it is explicitly trusted for OCSP signing. This is used to set
|
|
a root CA as a global signing root: that is any certificate that
|
|
chains to that CA is an acceptable OCSP signing certificate.
|
|
[Steve Henson]
|
|
|
|
*) New '-extfile ...' option to 'openssl ca' for reading X.509v3
|
|
extensions from a separate configuration file.
|
|
As when reading extensions from the main configuration file,
|
|
the '-extensions ...' option may be used for specifying the
|

section to use.

|
[Massimiliano Pala <madwolf@comune.modena.it>]
|
|
|
|
*) New OCSP utility. Allows OCSP requests to be generated or
|
|
read. The request can be sent to a responder and the output
|
|
parsed, outputted or printed in text form. Not complete yet:
|
|
still needs to check the OCSP response validity.
|
|
[Steve Henson]
|
|
|
|
*) New subcommands for 'openssl ca':
|
|
'openssl ca -status <serial>' prints the status of the cert with
|
|
the given serial number (according to the index file).
|
|
'openssl ca -updatedb' updates the expiry status of certificates
|
|
in the index file.
|
|
[Massimiliano Pala <madwolf@comune.modena.it>]
|
|
|
|
*) New '-newreq-nodes' command option to CA.pl. This is like
|
|
'-newreq', but calls 'openssl req' with the '-nodes' option
|
|
so that the resulting key is not encrypted.
|
|
[Damien Miller <djm@mindrot.org>]
|
|
|
|
*) New configuration for the GNU Hurd.
|
|
[Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
|
|
|
|
*) Initial code to implement OCSP basic response verify. This
|
|
is currently incomplete. Currently just finds the signer's
|
|
certificate and verifies the signature on the response.
|
|
[Steve Henson]
|
|
|
|
*) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
|
|
value of OPENSSLDIR. This is available via the new '-d' option
|
|
to 'openssl version', and is also included in 'openssl version -a'.
|
|
[Bodo Moeller]
|
|
|
|
*) Allowing defining memory allocation callbacks that will be given
|
|
file name and line number information in additional arguments
|
|
(a const char* and an int). The basic functionality remains, as
|
|
well as the original possibility to just replace malloc(),
|
|
realloc() and free() by functions that do not know about these
|
|
additional arguments. To register and find out the current
|
|
settings for extended allocation functions, the following
|
|
functions are provided:
|
|
|
|
CRYPTO_set_mem_ex_functions
|
|
CRYPTO_set_locked_mem_ex_functions
|
|
CRYPTO_get_mem_ex_functions
|
|
CRYPTO_get_locked_mem_ex_functions
|
|
|
|
These work the same way as CRYPTO_set_mem_functions and friends.
|
|
CRYPTO_get_[locked_]mem_functions now writes 0 where such an
|
|
extended allocation function is enabled.
|
|
Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
|
|
a conventional allocation function is enabled.
|
|
[Richard Levitte, Bodo Moeller]
|
|
|
|
*) Finish off removing the remaining LHASH function pointer casts.
|
|
There should no longer be any prototype-casting required when using
|
|
the LHASH abstraction, and any casts that remain are "bugs". See
|
|
the callback types and macros at the head of lhash.h for details
|
|
(and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
|
|
[Geoff Thorpe]
|
|
|
|
*) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
|
|
If /dev/[u]random devices are not available or do not return enough
|
|
entropy, EGD style sockets (served by EGD or PRNGD) will automatically
|
|
be queried.
|
|
The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
|
|
/etc/entropy will be queried once each in this sequence, querying stops
|
|
when enough entropy was collected without querying more sockets.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Change the Unix RAND_poll() variant to be able to poll several
|
|
random devices, as specified by DEVRANDOM, until a sufficient amount
|
|
of data has been collected. We spend at most 10 ms on each file
|
|
(select timeout) and read in non-blocking mode. DEVRANDOM now
|
|
defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
|
|
(previously it was just the string "/dev/urandom"), so on typical
|
|
platforms the 10 ms delay will never occur.
|
|
Also separate out the Unix variant to its own file, rand_unix.c.
|
|
For VMS, there's a currently-empty rand_vms.c.
|
|
[Richard Levitte]
|
|
|
|
*) Move OCSP client related routines to ocsp_cl.c. These
|
|
provide utility functions which an application needing
|
|
to issue a request to an OCSP responder and analyse the
|
|
response will typically need: as opposed to those which an
|
|
OCSP responder itself would need which will be added later.
|
|
|
|
OCSP_request_sign() signs an OCSP request with an API similar
|
|
to PKCS7_sign(). OCSP_response_status() returns status of OCSP
|
|
response. OCSP_response_get1_basic() extracts basic response
|
|
from response. OCSP_resp_find_status(): finds and extracts status
|
|
information from an OCSP_CERTID structure (which will be created
|
|
when the request structure is built). These are built from lower
|
|
level functions which work on OCSP_SINGLERESP structures but
|
|
won't normally be used unless the application wishes to examine
|
|
extensions in the OCSP response for example.
|
|
|
|
Replace nonce routines with a pair of functions.
|
|
OCSP_request_add1_nonce() adds a nonce value and optionally
|
|
generates a random value. OCSP_check_nonce() checks the
|
|
validity of the nonce in an OCSP response.
|
|
[Steve Henson]
|
|
|
|
*) Change function OCSP_request_add() to OCSP_request_add0_id().
|
|
This doesn't copy the supplied OCSP_CERTID and avoids the
|
|
need to free up the newly created id. Change return type
|
|
to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
|
|
This can then be used to add extensions to the request.
|
|
Deleted OCSP_request_new(), since most of its functionality
|
|
is now in OCSP_REQUEST_new() (and the case insensitive name
|
|
clash) apart from the ability to set the request name which
|
|
will be added elsewhere.
|
|
[Steve Henson]
|
|
|
|
*) Update OCSP API. Remove obsolete extensions argument from
|
|
various functions. Extensions are now handled using the new
|
|
OCSP extension code. New simple OCSP HTTP function which
|
|
can be used to send requests and parse the response.
|
|
[Steve Henson]
|
|
|
|
*) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
|
|
ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
|
|
uses the special reorder version of SET OF to sort the attributes
|
|
and reorder them to match the encoded order. This resolves a long
|
|
standing problem: a verify on a PKCS7 structure just after signing
|
|
it used to fail because the attribute order did not match the
|
|
encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
|
|
it uses the received order. This is necessary to tolerate some broken
|
|
software that does not order SET OF. This is handled by encoding
|
|
as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
|
|
to produce the required SET OF.
|
|
[Steve Henson]
|
|
|
|
*) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
|
|
OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
|
|
files to get correct declarations of the ASN.1 item variables.
|
|
[Richard Levitte]
|
|
|
|
*) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
|
|
PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
|
|
asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
|
|
NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
|
|
New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
|
|
ASN1_ITEM and no wrapper functions.
|
|
[Steve Henson]
|
|
|
|
*) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
|
|
replace the old function pointer based I/O routines. Change most of
|
|
the *_d2i_bio() and *_d2i_fp() functions to use these.
|
|
[Steve Henson]
|
|
|
|
*) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
|
|
lines, recognize more "algorithms" that can be deselected, and make
|
|
it complain about algorithm deselection that isn't recognised.
|
|
[Richard Levitte]
|
|
|
|
*) New ASN1 functions to handle dup, sign, verify, digest, pack and
|
|
unpack operations in terms of ASN1_ITEM. Modify existing wrappers
|
|
to use new functions. Add NO_ASN1_OLD which can be set to remove
|
|
some old style ASN1 functions: this can be used to determine if old
|
|
code will still work when these eventually go away.
|
|
[Steve Henson]
|
|
|
|
*) New extension functions for OCSP structures, these follow the
|
|
same conventions as certificates and CRLs.
|
|
[Steve Henson]
|
|
|
|
*) New function X509V3_add1_i2d(). This automatically encodes and
|
|
adds an extension. Its behaviour can be customised with various
|
|
flags to append, replace or delete. Various wrappers added for
|
|
certificates and CRLs.
|
|
[Steve Henson]
|
|
|
|
*) Fix to avoid calling the underlying ASN1 print routine when
|
|
an extension cannot be parsed. Correct a typo in the
|
|
OCSP_SERVICELOC extension. Tidy up print OCSP format.
|
|
[Steve Henson]
|
|
|
|
*) Make mkdef.pl parse some of the ASN1 macros and add appropriate
|
|
entries for variables.
|
|
[Steve Henson]
|
|
|
|
*) Add functionality to apps/openssl.c for detecting locking
|
|
problems: As the program is single-threaded, all we have
|
|
to do is register a locking callback using an array for
|
|
storing which locks are currently held by the program.
|
|
[Bodo Moeller]
|
|
|
|
*) Use a lock around the call to CRYPTO_get_ex_new_index() in
|
|
SSL_get_ex_data_X509_STORE_idx(), which is used in
|
|
ssl_verify_cert_chain() and thus can be called at any time
|
|
during TLS/SSL handshakes so that thread-safety is essential.
|
|
Unfortunately, the ex_data design is not at all suited
|
|
for multi-threaded use, so it probably should be abolished.
|
|
[Bodo Moeller]
|
|
|
|
*) Added Broadcom "ubsec" ENGINE to OpenSSL.
|
|
[Broadcom, tweaked and integrated by Geoff Thorpe]
|
|
|
|
*) Move common extension printing code to new function
|
|
X509V3_print_extensions(). Reorganise OCSP print routines and
|
|
implement some needed OCSP ASN1 functions. Add OCSP extensions.
|
|
[Steve Henson]
|
|
|
|
*) New function X509_signature_print() to remove duplication in some
|
|
print routines.
|
|
[Steve Henson]
|
|
|
|
*) Add a special meaning when SET OF and SEQUENCE OF flags are both
|
|
set (this was treated exactly the same as SET OF previously). This
|
|
is used to reorder the STACK representing the structure to match the
|
|
encoding. This will be used to get round a problem where a PKCS7
|
|
structure which was signed could not be verified because the STACK
|
|
order did not reflect the encoded order.
|
|
[Steve Henson]
|
|
|
|
*) Reimplement the OCSP ASN1 module using the new code.
|
|
[Steve Henson]
|
|
|
|
*) Update the X509V3 code to permit the use of an ASN1_ITEM structure
|
|
for its ASN1 operations. The old style function pointers still exist
|
|
for now but they will eventually go away.
|
|
[Steve Henson]
|
|
|
|
*) Merge in replacement ASN1 code from the ASN1 branch. This almost
|
|
completely replaces the old ASN1 functionality with a table driven
|
|
encoder and decoder which interprets an ASN1_ITEM structure describing
|
|
the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
|
|
largely maintained. Almost all of the old asn1_mac.h macro based ASN1
|
|
has also been converted to the new form.
|
|
[Steve Henson]
|
|
|
|
*) Change BN_mod_exp_recp so that negative moduli are tolerated
|
|
(the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
|
|
so that BN_mod_exp_mont and BN_mod_exp_mont_word work
|
|
for negative moduli.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix BN_uadd and BN_usub: Always return non-negative results instead
|
|
of not touching the result's sign bit.
|
|
[Bodo Moeller]
|
|
|
|
*) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
|
|
set.
|
|
[Bodo Moeller]
|
|
|
|
*) Changed the LHASH code to use prototypes for callbacks, and created
|
|
macros to declare and implement thin (optionally static) functions
|
|
that provide type-safety and avoid function pointer casting for the
|
|
type-specific callbacks.
|
|
[Geoff Thorpe]
|
|
|
|
*) Added Kerberos Cipher Suites to be used with TLS, as written in
|
|
RFC 2712.
|
|
[Veers Staats <staatsvr@asc.hpc.mil>,
|
|
Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
|
|
|
|
*) Reformat the FAQ so the different questions and answers can be divided
|
|
in sections depending on the subject.
|
|
[Richard Levitte]
|
|
|
|
*) Have the zlib compression code load ZLIB.DLL dynamically under
|
|
Windows.
|
|
[Richard Levitte]
|
|
|
|
*) New function BN_mod_sqrt for computing square roots modulo a prime
|
|
(using the probabilistic Tonelli-Shanks algorithm unless
|
|
p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
|
|
be handled deterministically).
|
|
[Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
|
|
|
|
*) Make BN_mod_inverse faster by explicitly handling small quotients
|
|
in the Euclid loop. (Speed gain about 20% for small moduli [256 or
|
|
512 bits], about 30% for larger ones [1024 or 2048 bits].)
|
|
[Bodo Moeller]
|
|
|
|
*) New function BN_kronecker.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix BN_gcd so that it works on negative inputs; the result is
|
|
positive unless both parameters are zero.
|
|
Previously something reasonably close to an infinite loop was
|
|
possible because numbers could be growing instead of shrinking
|
|
in the implementation of Euclid's algorithm.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix BN_is_word() and BN_is_one() macros to take into account the
|
|
sign of the number in question.
|
|
|
|
Fix BN_is_word(a,w) to work correctly for w == 0.
|
|
|
|
The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
|
|
because its test if the absolute value of 'a' equals 'w'.
|
|
Note that BN_abs_is_word does *not* handle w == 0 reliably;
|
|
it exists mostly for use in the implementations of BN_is_zero(),
|
|
BN_is_one(), and BN_is_word().
|
|
[Bodo Moeller]
|
|
|
|
*) New function BN_swap.
|
|
[Bodo Moeller]
|
|
|
|
*) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
|
|
the exponentiation functions are more likely to produce reasonable
|
|
results on negative inputs.
|
|
[Bodo Moeller]
|
|
|
|
*) Change BN_mod_mul so that the result is always non-negative.
|
|
Previously, it could be negative if one of the factors was negative;
|
|
I don't think anyone really wanted that behaviour.
|
|
[Bodo Moeller]
|
|
|
|
*) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
|
|
(except for exponentiation, which stays in crypto/bn/bn_exp.c,
|
|
and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
|
|
and add new functions:
|
|
|
|
BN_nnmod
|
|
BN_mod_sqr
|
|
BN_mod_add
|
|
BN_mod_add_quick
|
|
BN_mod_sub
|
|
BN_mod_sub_quick
|
|
BN_mod_lshift1
|
|
BN_mod_lshift1_quick
|
|
BN_mod_lshift
|
|
BN_mod_lshift_quick
|
|
|
|
These functions always generate non-negative results.
|
|
|
|
BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
|
|
such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
|
|
|
|
BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
|
|
BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
|
|
be reduced modulo m.
|
|
[Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]

#if 0
|
|
The following entry accidentally appeared in the CHANGES file
|
|
distributed with OpenSSL 0.9.7. The modifications described in
|
|
it do *not* apply to OpenSSL 0.9.7.
|
|
|
|
*) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
|
|
was actually never needed) and in BN_mul(). The removal in BN_mul()
|
|
required a small change in bn_mul_part_recursive() and the addition
|
|
of the functions bn_cmp_part_words(), bn_sub_part_words() and
|
|
bn_add_part_words(), which do the same thing as bn_cmp_words(),
|
|
bn_sub_words() and bn_add_words() except they take arrays with
|
|
differing sizes.
|
|
[Richard Levitte]
|
|
#endif
|
|
|
|
*) In 'openssl passwd', verify passwords read from the terminal
|
|
unless the '-salt' option is used (which usually means that
|
|
verification would just waste user's time since the resulting
|
|
hash is going to be compared with some given password hash)
|
|
or the new '-noverify' option is used.
|
|
|
|
This is an incompatible change, but it does not affect
|
|
non-interactive use of 'openssl passwd' (passwords on the command
|
|
line, '-stdin' option, '-in ...' option) and thus should not
|
|
cause any problems.
|
|
[Bodo Moeller]
|
|
|
|
*) Remove all references to RSAref, since there's no more need for it.
|
|
[Richard Levitte]
|
|
|
|
*) Make DSO load along a path given through an environment variable
|
|
(SHLIB_PATH) with shl_load().
|
|
[Richard Levitte]
|
|
|
|
*) Constify the ENGINE code as a result of BIGNUM constification.
|
|
Also constify the RSA code and most things related to it. In a
|
|
few places, most notable in the depth of the ASN.1 code, ugly
|
|
casts back to non-const were required (to be solved at a later
|
|
time)
|
|
[Richard Levitte]
|
|
|
|
*) Make it so the openssl application has all engines loaded by default.
|
|
[Richard Levitte]
|
|
|
|
*) Constify the BIGNUM routines a little more.
|
|
[Richard Levitte]
|
|
|
|
*) Add the following functions:
|
|
|
|
ENGINE_load_cswift()
|
|
ENGINE_load_chil()
|
|
ENGINE_load_atalla()
|
|
ENGINE_load_nuron()
|
|
ENGINE_load_builtin_engines()
|
|
|
|
That way, an application can itself choose if external engines that
|
|
are built-in in OpenSSL shall ever be used or not. The benefit is
|
|
that applications won't have to be linked with libdl or other dso
|
|
libraries unless it's really needed.
|
|
|
|
Changed 'openssl engine' to load all engines on demand.
|
|
Changed the engine header files to avoid the duplication of some
|
|
declarations (they differed!).
|
|
[Richard Levitte]
|
|
|
|
*) 'openssl engine' can now list capabilities.
|
|
[Richard Levitte]
|
|
|
|
*) Better error reporting in 'openssl engine'.
|
|
[Richard Levitte]
|
|
|
|
*) Never call load_dh_param(NULL) in s_server.
|
|
[Bodo Moeller]
|
|
|
|
*) Add engine application. It can currently list engines by name and
|
|
identity, and test if they are actually available.
|
|
[Richard Levitte]
|
|
|
|
*) Improve RPM specification file by forcing symbolic linking and making
|
|
sure the installed documentation is also owned by root.root.
|
|
[Damien Miller <djm@mindrot.org>]
|
|
|
|
*) Give the OpenSSL applications more possibilities to make use of
|
|
keys (public as well as private) handled by engines.
|
|
[Richard Levitte]
|
|
|
|
*) Add OCSP code that comes from CertCo.
|
|
[Richard Levitte]
|
|
|
|
*) Add VMS support for the Rijndael code.
|
|
[Richard Levitte]
|
|
|
|
*) Added untested support for Nuron crypto accelerator.
|
|
[Ben Laurie]
|
|
|
|
*) Add support for external cryptographic devices. This code was
|
|
previously distributed separately as the "engine" branch.
|
|
[Geoff Thorpe, Richard Levitte]
|
|
|
|
*) Rework the filename-translation in the DSO code. It is now possible to
|
|
have far greater control over how a "name" is turned into a filename
|
|
depending on the operating environment and any oddities about the
|
|
different shared library filenames on each system.
|
|
[Geoff Thorpe]
|
|
|
|
*) Support threads on FreeBSD-elf in Configure.
|
|
[Richard Levitte]
|
|
|
|
*) Fix for SHA1 assembly problem with MASM: it produces
|
|
warnings about corrupt line number information when assembling
|
|
with debugging information. This is caused by the overlapping
|
|
of two sections.
|
|
[Bernd Matthes <mainbug@celocom.de>, Steve Henson]
|
|
|
|
*) NCONF changes.
|
|
NCONF_get_number() has no error checking at all. As a replacement,
|
|
NCONF_get_number_e() is defined (_e for "error checking") and is
|
|
promoted strongly. The old NCONF_get_number is kept around for
|
|
binary backward compatibility.
|
|
Make it possible for methods to load from something other than a BIO,
|
|
by providing a function pointer that is given a name instead of a BIO.
|
|
For example, this could be used to load configuration data from an
|
|
LDAP server.
|
|
[Richard Levitte]
|
|
|
|
*) Fix for non blocking accept BIOs. Added new I/O special reason
|
|
BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
|
|
with non blocking I/O was not possible because no retry code was
|
|
implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
|
|
this case.
|
|
[Steve Henson]
|
|
|
|
*) Added the beginnings of Rijndael support.
|
|
[Ben Laurie]
|
|
|
|
*) Fix for bug in DirectoryString mask setting. Add support for
|
|
X509_NAME_print_ex() in 'req' and X509_print_ex() function
|
|
to allow certificate printing to more controllable, additional
|
|
'certopt' option to 'x509' to allow new printing options to be

Changes between 0.9.6l and 0.9.6m [17 Mar 2004]
|
|
|
|
*) Fix null-pointer assignment in do_change_cipher_spec() revealed
|
|
by using the Codenomicon TLS Test Tool (CVE-2004-0079)
|
|
[Joe Orton, Steve Henson]
|
|
|
|
Changes between 0.9.6k and 0.9.6l [04 Nov 2003]
|
|
|
|
*) Fix additional bug revealed by the NISCC test suite:
|
|
|
|
Stop bug triggering large recursion when presented with
|
|
certain ASN.1 tags (CVE-2003-0851)
|
|
[Steve Henson]
|
|
|
|
Changes between 0.9.6j and 0.9.6k [30 Sep 2003]
|
|
|
|
*) Fix various bugs revealed by running the NISCC test suite:
|
|
|
|
Stop out of bounds reads in the ASN1 code when presented with
|
|
invalid tags (CVE-2003-0543 and CVE-2003-0544).
|
|
|
|
If verify callback ignores invalid public key errors don't try to check
|
|
certificate signature with the NULL public key.
|
|
|
|
[Steve Henson]
|
|
|
|
*) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
|
|
if the server requested one: as stated in TLS 1.0 and SSL 3.0
|
|
specifications.
|
|
[Steve Henson]
|
|
|
|
*) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
|
|
extra data after the compression methods not only for TLS 1.0
|
|
but also for SSL 3.0 (as required by the specification).
|
|
[Bodo Moeller; problem pointed out by Matthias Loepfe]
|
|
|
|
*) Change X509_certificate_type() to mark the key as exported/exportable
|
|
when it's 512 *bits* long, not 512 bytes.
|
|
[Richard Levitte]
|
|
|
|
Changes between 0.9.6i and 0.9.6j [10 Apr 2003]
|
|
|
|
*) Countermeasure against the Klima-Pokorny-Rosa extension of
|
|
Bleichbacher's attack on PKCS #1 v1.5 padding: treat
|
|
a protocol version number mismatch like a decryption error
|
|
in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
|
|
[Bodo Moeller]
|
|
|
|
*) Turn on RSA blinding by default in the default implementation
|
|
to avoid a timing attack. Applications that don't want it can call
|
|
RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
|
|
They would be ill-advised to do so in most cases.
|
|
[Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
|
|
|
|
*) Change RSA blinding code so that it works when the PRNG is not
|
|
seeded (in this case, the secret RSA exponent is abused as
|
|
an unpredictable seed -- if it is not unpredictable, there
|
|
is no point in blinding anyway). Make RSA blinding thread-safe
|
|
by remembering the creator's thread ID in rsa->blinding and
|
|
having all other threads use local one-time blinding factors
|
|
(this requires more computation than sharing rsa->blinding, but
|
|
avoids excessive locking; and if an RSA object is not shared
|
|
between threads, blinding will still be very fast).
|
|
[Bodo Moeller]
|
|
|
|
Changes between 0.9.6h and 0.9.6i [19 Feb 2003]
|
|
|
|
*) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
|
|
via timing by performing a MAC computation even if incorrect
|
|
block cipher padding has been found. This is a countermeasure
|
|
against active attacks where the attacker has to distinguish
|
|
between bad padding and a MAC verification error. (CVE-2003-0078)
|
|
|
|
[Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
|
|
Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
|
|
Martin Vuagnoux (EPFL, Ilion)]
|
|
|
|
Changes between 0.9.6g and 0.9.6h [5 Dec 2002]
|
|
|
|
*) New function OPENSSL_cleanse(), which is used to cleanse a section of
|
|
memory from its contents. This is done with a counter that will
|
|
place alternating values in each byte. This can be used to solve
|
|
two issues: 1) the removal of calls to memset() by highly optimizing
|
|
compilers, and 2) cleansing with other values than 0, since those can
|
|
be read through on certain media, for example a swap space on disk.
|
|
[Geoff Thorpe]
|
|
|
|
*) Bugfix: client side session caching did not work with external caching,
|
|
because the session->cipher setting was not restored when reloading
|
|
from the external cache. This problem was masked, when
|
|
SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set.
|
|
(Found by Steve Haslam <steve@araqnid.ddts.net>.)
|
|
[Lutz Jaenicke]
|
|
|
|
*) Fix client_certificate (ssl/s2_clnt.c): The permissible total
|
|
length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
|
|
[Zeev Lieber <zeev-l@yahoo.com>]
|
|
|
|
*) Undo an undocumented change introduced in 0.9.6e which caused
|
|
repeated calls to OpenSSL_add_all_ciphers() and
|
|
OpenSSL_add_all_digests() to be ignored, even after calling
|
|
EVP_cleanup().
|
|
[Richard Levitte]
|
|
|
|
*) Change the default configuration reader to deal with last line not
|
|
being properly terminated.
|
|
[Richard Levitte]
|
|
|
|
*) Change X509_NAME_cmp() so it applies the special rules on handling
|
|
DN values that are of type PrintableString, as well as RDNs of type
|
|
emailAddress where the value has the type ia5String.
|
|
[stefank@valicert.com via Richard Levitte]
|
|
|
|
*) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half
|
|
the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
|
|
doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
|
|
the bitwise-OR of the two for use by the majority of applications
|
|
wanting this behaviour, and update the docs. The documented
|
|
behaviour and actual behaviour were inconsistent and had been
|
|
changing anyway, so this is more a bug-fix than a behavioural
|
|
change.
|
|
[Geoff Thorpe, diagnosed by Nadav Har'El]
|
|
|
|
*) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
|
|
(the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
|
|
[Bodo Moeller]
|
|
|
|
*) Fix initialization code race conditions in
|
|
SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),
|
|
SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(),
|
|
SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(),
|
|
TLSv1_method(), TLSv1_client_method(), TLSv1_server_method(),
|

ssl2_get_cipher_by_char(),
|
|
ssl3_get_cipher_by_char().
|
|
[Patrick McCormick <patrick@tellme.com>, Bodo Moeller]
|
|
|
|
*) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
|
|
the cached sessions are flushed, as the remove_cb() might use ex_data
|
|
contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com>
|
|
(see [openssl.org #212]).
|
|
[Geoff Thorpe, Lutz Jaenicke]
|
|
|
|
*) Fix typo in OBJ_txt2obj which incorrectly passed the content
|
|
length, instead of the encoding length to d2i_ASN1_OBJECT.
|
|
[Steve Henson]
|
|
|
|
Changes between 0.9.6f and 0.9.6g [9 Aug 2002]
|
|
|
|
*) [In 0.9.6g-engine release:]
|
|
Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall').
|
|
[Lynn Gazis <lgazis@rainbow.com>]
|
|
|
|
Changes between 0.9.6e and 0.9.6f [8 Aug 2002]
|
|
|
|
*) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX
|
|
and get fix the header length calculation.
|
|
[Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>,
|
|
Alon Kantor <alonk@checkpoint.com> (and others),
|
|
Steve Henson]
|
|
|
|
*) Use proper error handling instead of 'assertions' in buffer
|
|
overflow checks added in 0.9.6e. This prevents DoS (the
|
|
assertions could call abort()).
|
|
[Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]
|
|
|
|
Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
|
|
|
|
*) Add various sanity checks to asn1_get_length() to reject
|
|
the ASN1 length bytes if they exceed sizeof(long), will appear
|
|
negative or the content length exceeds the length of the
|
|
supplied buffer.
|
|
[Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
|
|
|
|
*) Fix cipher selection routines: ciphers without encryption had no flags
|
|
for the cipher strength set and where therefore not handled correctly
|
|
by the selection routines (PR #130).
|
|
[Lutz Jaenicke]
|
|
|
|
*) Fix EVP_dsa_sha macro.
|
|
[Nils Larsch]
|
|
|
|
*) New option
|
|
SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
|
|
for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
|
|
that was added in OpenSSL 0.9.6d.
|
|
|
|
As the countermeasure turned out to be incompatible with some
|
|
broken SSL implementations, the new option is part of SSL_OP_ALL.
|
|
SSL_OP_ALL is usually employed when compatibility with weird SSL
|
|
implementations is desired (e.g. '-bugs' option to 's_client' and
|
|
's_server'), so the new option is automatically set in many
|
|
applications.
|
|
[Bodo Moeller]
|
|
|
|
*) Changes in security patch:
|
|
|
|
Changes marked "(CHATS)" were sponsored by the Defense Advanced
|
|
Research Projects Agency (DARPA) and Air Force Research Laboratory,
|
|
Air Force Materiel Command, USAF, under agreement number
|
|
F30602-01-2-0537.
|
|
|
|
*) Add various sanity checks to asn1_get_length() to reject
|
|
the ASN1 length bytes if they exceed sizeof(long), will appear
|
|
negative or the content length exceeds the length of the
|
|
supplied buffer. (CVE-2002-0659)
|
|
[Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
|
|
|
|
*) Assertions for various potential buffer overflows, not known to
|
|
happen in practice.
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Various temporary buffers to hold ASCII versions of integers were
|
|
too small for 64 bit platforms. (CVE-2002-0655)
|
|
[Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
|
|
|
|
*) Remote buffer overflow in SSL3 protocol - an attacker could
|
|
supply an oversized session ID to a client. (CVE-2002-0656)
|
|
[Ben Laurie (CHATS)]
|
|
|
|
*) Remote buffer overflow in SSL2 protocol - an attacker could
|
|
supply an oversized client master key. (CVE-2002-0656)
|
|
[Ben Laurie (CHATS)]
|
|
|
|
Changes between 0.9.6c and 0.9.6d [9 May 2002]
|
|
|
|
*) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
|
|
encoded as NULL) with id-dsa-with-sha1.
|
|
[Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
|
|
|
|
*) Check various X509_...() return values in apps/req.c.
|
|
[Nils Larsch <nla@trustcenter.de>]
|
|
|
|
*) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
|
|
an end-of-file condition would erroneously be flagged, when the CRLF
|
|
was just at the end of a processed block. The bug was discovered when
|
|
processing data through a buffering memory BIO handing the data to a
|
|
BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
|
|
<ptsekov@syntrex.com> and Nedelcho Stanev.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Implement a countermeasure against a vulnerability recently found
|
|
in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
|
|
before application data chunks to avoid the use of known IVs
|
|
with data potentially chosen by the attacker.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix length checks in ssl3_get_client_hello().
|
|
[Bodo Moeller]
|
|
|
|
*) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
|
|
to prevent ssl3_read_internal() from incorrectly assuming that
|
|
ssl3_read_bytes() found application data while handshake
|
|
processing was enabled when in fact s->s3->in_read_app_data was
|
|
merely automatically cleared during the initial handshake.
|
|
[Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
|
|
|
|
*) Fix object definitions for Private and Enterprise: they were not
|
|
recognized in their shortname (=lowercase) representation. Extend
|
|
obj_dat.pl to issue an error when using undefined keywords instead
|
|
of silently ignoring the problem (Svenning Sorensen
|
|
<sss@sss.dnsalias.net>).
|
|
[Lutz Jaenicke]
|
|
|
|
*) Fix DH_generate_parameters() so that it works for 'non-standard'
|
|
generators, i.e. generators other than 2 and 5. (Previously, the
|
|
code did not properly initialise the 'add' and 'rem' values to
|
|
BN_generate_prime().)
|
|
|
|
In the new general case, we do not insist that 'generator' is
|
|
actually a primitive root: This requirement is rather pointless;
|
|
a generator of the order-q subgroup is just as good, if not
|
|
better.
|
|
[Bodo Moeller]
|
|
|
|
*) Map new X509 verification errors to alerts. Discovered and submitted by
|
|
Tom Wu <tom@arcot.com>.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
|
|
returning non-zero before the data has been completely received
|
|
when using non-blocking I/O.
|
|
[Bodo Moeller; problem pointed out by John Hughes]
|
|
|
|
*) Some of the ciphers missed the strength entry (SSL_LOW etc).
|
|
[Ben Laurie, Lutz Jaenicke]
|
|
|
|
*) Fix bug in SSL_clear(): bad sessions were not removed (found by
|
|
Yoram Zahavi <YoramZ@gilian.com>).
|
|
[Lutz Jaenicke]
|
|
|
|
*) Add information about CygWin 1.3 and on, and preserve proper
|
|
configuration for the versions before that.
|
|
[Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
|
|
|
|
*) Make removal from session cache (SSL_CTX_remove_session()) more robust:
|
|
check whether we deal with a copy of a session and do not delete from
|
|
the cache in this case. Problem reported by "Izhar Shoshani Levi"
|
|
<izhar@checkpoint.com>.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Do not store session data into the internal session cache, if it
|
|
is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
|
|
flag is set). Proposed by Aslam <aslam@funk.com>.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
|
|
value is 0.
|
|
[Richard Levitte]
|
|
|
|
*) [In 0.9.6d-engine release:]
|
|
Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
|
|
[Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
|
|
|
|
*) Add the configuration target linux-s390x.
|
|
[Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
|
|
|
|
*) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
|
|
ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
|
|
variable as an indication that a ClientHello message has been
|
|
received. As the flag value will be lost between multiple
|
|
invocations of ssl3_accept when using non-blocking I/O, the
|
|
function may not be aware that a handshake has actually taken
|
|
place, thus preventing a new session from being added to the
|
|
session cache.
|
|
|
|
To avoid this problem, we now set s->new_session to 2 instead of
|
|
using a local variable.
|
|
[Lutz Jaenicke, Bodo Moeller]
|
|
|
|
*) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
|
|
if the SSL_R_LENGTH_MISMATCH error is detected.
|
|
[Geoff Thorpe, Bodo Moeller]
|
|
|
|
*) New 'shared_ldflag' column in Configure platform table.
|
|
[Richard Levitte]
|
|
|
|
*) Fix EVP_CIPHER_mode macro.
|
|
["Dan S. Camper" <dan@bti.net>]
|
|
|
|
*) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
|
|
type, we must throw them away by setting rr->length to 0.
|
|
[D P Chang <dpc@qualys.com>]
|
|
|
|
Changes between 0.9.6b and 0.9.6c [21 dec 2001]
|
|
|
|
*) Fix BN_rand_range bug pointed out by Dominikus Scherkl
|
|
<Dominikus.Scherkl@biodata.com>. (The previous implementation
|
|
worked incorrectly for those cases where range = 10..._2 and
|
|
3*range is two bits longer than range.)
|
|
[Bodo Moeller]
|
|
|
|
*) Only add signing time to PKCS7 structures if it is not already
|
|
present.
|
|
[Steve Henson]
|
|
|
|
*) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
|
|
OBJ_ld_ce should be OBJ_id_ce.
|
|
Also some ip-pda OIDs in crypto/objects/objects.txt were
|
|
incorrect (cf. RFC 3039).
|
|
[Matt Cooper, Frederic Giudicelli, Bodo Moeller]
|
|
|
|
*) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
|
|
returns early because it has nothing to do.
|
|
[Andy Schneider <andy.schneider@bjss.co.uk>]
|
|
|
|
*) [In 0.9.6c-engine release:]
|
|
Fix mutex callback return values in crypto/engine/hw_ncipher.c.
|
|
[Andy Schneider <andy.schneider@bjss.co.uk>]
|
|
|
|
*) [In 0.9.6c-engine release:]
|
|
Add support for Cryptographic Appliance's keyserver technology.
|
|
(Use engine 'keyclient')
|
|
[Cryptographic Appliances and Geoff Thorpe]
|
|
|
|
*) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
|
|
is called via tools/c89.sh because arguments have to be
|
|
rearranged (all '-L' options must appear before the first object
|
|
modules).
|
|
[Richard Shapiro <rshapiro@abinitio.com>]
|
|
|
|
*) [In 0.9.6c-engine release:]
|
|
Add support for Broadcom crypto accelerator cards, backported
|
|
from 0.9.7.
|
|
[Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
|
|
|
|
*) [In 0.9.6c-engine release:]
|
|
Add support for SureWare crypto accelerator cards from
|
|
Baltimore Technologies. (Use engine 'sureware')
|
|
[Baltimore Technologies and Mark Cox]
|
|
|
|
*) [In 0.9.6c-engine release:]
|
|
Add support for crypto accelerator cards from Accelerated
|
|
Encryption Processing, www.aep.ie. (Use engine 'aep')
|
|
[AEP Inc. and Mark Cox]
|
|
|
|
*) Add a configuration entry for gcc on UnixWare.
|
|
[Gary Benson <gbenson@redhat.com>]
|
|
|
|
*) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
|
|
messages are stored in a single piece (fixed-length part and
|
|
variable-length part combined) and fix various bugs found on the way.
|
|
[Bodo Moeller]
|
|
|
|
*) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
|
|
instead. BIO_gethostbyname() does not know what timeouts are
|
|
appropriate, so entries would stay in cache even when they have
|
|
become invalid.
|
|
[Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
|
|
|
|
*) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
|
|
faced with a pathologically small ClientHello fragment that does
|
|
not contain client_version: Instead of aborting with an error,
|
|
simply choose the highest available protocol version (i.e.,
|
|
TLS 1.0 unless it is disabled). In practice, ClientHello
|
|
messages are never sent like this, but this change gives us
|
|
strictly correct behaviour at least for TLS.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
|
|
never resets s->method to s->ctx->method when called from within
|
|
one of the SSL handshake functions.
|
|
[Bodo Moeller; problem pointed out by Niko Baric]
|
|
|
|
*) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
|
|
(sent using the client's version number) if client_version is
|
|
smaller than the protocol version in use. Also change
|
|
ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
|
|
the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
|
|
the client will at least see that alert.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
|
|
correctly.
|
|
[Bodo Moeller]
|
|
|
|
*) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
|
|
client receives HelloRequest while in a handshake.

[Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
|
|
|
|
*) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
|
|
should end in 'break', not 'goto end' which circumvents various
|
|
cleanups done in state SSL_ST_OK. But session related stuff
|
|
must be disabled for SSL_ST_OK in the case that we just sent a
|
|
HelloRequest.
|
|
|
|
Also avoid some overhead by not calling ssl_init_wbio_buffer()
|
|
before just sending a HelloRequest.
|
|
[Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
|
|
|
|
*) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
|
|
reveal whether illegal block cipher padding was found or a MAC
|
|
verification error occurred. (Neither SSLerr() codes nor alerts
|
|
are directly visible to potential attackers, but the information
|
|
may leak via logfiles.)
|
|
|
|
Similar changes are not required for the SSL 2.0 implementation
|
|
because the number of padding bytes is sent in clear for SSL 2.0,
|
|
and the extra bytes are just ignored. However ssl/s2_pkt.c
|
|
failed to verify that the purported number of padding bytes is in
|
|
the legal range.
|
|
[Bodo Moeller]
|
|
|
|
*) Add OpenUNIX-8 support including shared libraries
|
|
(Boyd Lynn Gerber <gerberb@zenez.com>).
|
|
[Lutz Jaenicke]
|
|
|
|
*) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
|
|
'wristwatch attack' using huge encoding parameters (cf.
|
|
James H. Manger's CRYPTO 2001 paper). Note that the
|
|
RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
|
|
encoding parameters and hence was not vulnerable.
|
|
[Bodo Moeller]
|
|
|
|
*) BN_sqr() bug fix.
|
|
[Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
|
|
|
|
*) Rabin-Miller test analyses assume uniformly distributed witnesses,
|
|
so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
|
|
followed by modular reduction.
|
|
[Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
|
|
|
|
*) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
|
|
equivalent based on BN_pseudo_rand() instead of BN_rand().
|
|
[Bodo Moeller]
|
|
|
|
*) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
|
|
This function was broken, as the check for a new client hello message
|
|
to handle SGC did not allow these large messages.
|
|
(Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
|
|
[Lutz Jaenicke]
|
|
|
|
*) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
|
|
[Lutz Jaenicke]
|
|
|
|
*) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
|
|
for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
|
|
[Lutz Jaenicke]
|
|
|
|
*) Rework the configuration and shared library support for Tru64 Unix.
|
|
The configuration part makes use of modern compiler features and
|
|
still retains old compiler behavior for those that run older versions
|
|
of the OS. The shared library support part includes a variant that
|
|
uses the RPATH feature, and is available through the special
|
|
configuration target "alpha-cc-rpath", which will never be selected
|
|
automatically.
|
|
[Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
|
|
|
|
*) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
|
|
with the same message size as in ssl3_get_certificate_request().
|
|
Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
|
|
messages might inadvertently be reject as too long.
|
|
[Petr Lampa <lampa@fee.vutbr.cz>]
|
|
|
|
*) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
|
|
[Andy Polyakov]
|
|
|
|
*) Modified SSL library such that the verify_callback that has been set
|
|
specifically for an SSL object with SSL_set_verify() is actually being
|
|
used. Before the change, a verify_callback set with this function was
|
|
ignored and the verify_callback() set in the SSL_CTX at the time of
|
|
the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
|
|
to allow the necessary settings.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
|
|
explicitly to NULL, as at least on Solaris 8 this seems not always to be
|
|
done automatically (in contradiction to the requirements of the C
|
|
standard). This made problems when used from OpenSSH.
|
|
[Lutz Jaenicke]
|
|
|
|
*) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
|
|
dh->length and always used
|
|
|
|
BN_rand_range(priv_key, dh->p).
|
|
|
|
BN_rand_range() is not necessary for Diffie-Hellman, and this
|
|
specific range makes Diffie-Hellman unnecessarily inefficient if
|
|
dh->length (recommended exponent length) is much smaller than the
|
|
length of dh->p. We could use BN_rand_range() if the order of
|
|
the subgroup was stored in the DH structure, but we only have
|
|
dh->length.
|
|
|
|
So switch back to
|
|
|
|
BN_rand(priv_key, l, ...)
|
|
|
|
where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
|
|
otherwise.

|
*) In

|
|
|
RSA_eay_public_encrypt
|
|
RSA_eay_private_decrypt
|
|
RSA_eay_private_encrypt (signing)
|
|
RSA_eay_public_decrypt (signature verification)
|
|
|
|
(default implementations for RSA_public_encrypt,

|
RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
|
|
always reject numbers >= n.
|
|
[Bodo Moeller]
|
|
|
|
*) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
|
|
to synchronize access to 'locking_thread'. This is necessary on
|
|
systems where access to 'locking_thread' (an 'unsigned long'
|
|
variable) is not atomic.
|
|
[Bodo Moeller]
|
|
|
|
*) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
|
|
*before* setting the 'crypto_lock_rand' flag. The previous code had
|
|
a race condition if 0 is a valid thread ID.
|
|
[Travis Vitek <vitek@roguewave.com>]
|
|
|
|
*) Add support for shared libraries under Irix.
|
|
[Albert Chin-A-Young <china@thewrittenword.com>]
|
|
|
|
*) Add configuration option to build on Linux on both big-endian and
|
|
little-endian MIPS.
|
|
[Ralf Baechle <ralf@uni-koblenz.de>]
|
|
|
|
*) Add the possibility to create shared libraries on HP-UX.

|
[Richard Levitte]
|
|
|
|
Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
|
|
|
|
*) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
|
|
to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
|
|
Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
|
|
PRNG state recovery was possible based on the output of
|
|
one PRNG request appropriately sized to gain knowledge on
|
|
'md' followed by enough consecutive 1-byte PRNG requests
|
|
to traverse all of 'state'.
|
|
|
|
1. When updating 'md_local' (the current thread's copy of 'md')
|
|
during PRNG output generation, hash all of the previous
|
|
'md_local' value, not just the half used for PRNG output.
|
|
|
|
2. Make the number of bytes from 'state' included into the hash
|
|
independent from the number of PRNG bytes requested.
|
|
|
|
The first measure alone would be sufficient to avoid
|
|
Markku-Juhani's attack. (Actually it had never occurred
|
|
to me that the half of 'md_local' used for chaining was the
|
|
half from which PRNG output bytes were taken -- I had always
|
|
assumed that the secret half would be used.) The second
|
|
measure makes sure that additional data from 'state' is never
|
|
mixed into 'md_local' in small portions; this heuristically
|
|
further strengthens the PRNG.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix crypto/bn/asm/mips3.s.
|
|
[Andy Polyakov]
|
|
|
|
*) When only the key is given to "enc", the IV is undefined. Print out
|
|
an error message in this case.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Handle special case when X509_NAME is empty in X509 printing routines.
|
|
[Steve Henson]
|
|
|
|
*) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
|
|
positive and less than q.
|
|
[Bodo Moeller]
|
|
|
|
*) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
|
|
used: it isn't thread safe and the add_lock_callback should handle
|
|
that itself.
|
|
[Paul Rose <Paul.Rose@bridge.com>]
|
|
|
|
*) Verify that incoming data obeys the block size in
|
|
ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
|
|
[Bodo Moeller]
|
|
|
|
*) Fix OAEP check.
|
|
[Ulf Möller, Bodo Möller]
|
|
|
|
*) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
|
|
RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
|
|
when fixing the server behaviour for backwards-compatible 'client
|
|
hello' messages. (Note that the attack is impractical against
|
|
SSL 3.0 and TLS 1.0 anyway because length and version checking
|
|
means that the probability of guessing a valid ciphertext is
|
|
around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
|
|
paper.)
|
|
|
|
Before 0.9.5, the countermeasure (hide the error by generating a
|
|
random 'decryption result') did not work properly because
|
|
ERR_clear_error() was missing, meaning that SSL_get_error() would
|
|
detect the supposedly ignored error.
|
|
|
|
Both problems are now fixed.
|
|
[Bodo Moeller]
|
|
|
|
*) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
|
|
(previously it was 1024).
|
|
[Bodo Moeller]
|
|
|
|
*) Fix for compatibility mode trust settings: ignore trust settings
|
|
unless some valid trust or reject settings are present.
|
|
[Steve Henson]
|
|
|
|
*) Fix for blowfish EVP: its a variable length cipher.
|
|
[Steve Henson]
|
|
|
|
*) Fix various bugs related to DSA S/MIME verification. Handle missing
|
|
parameters in DSA public key structures and return an error in the
|
|
DSA routines if parameters are absent.
|
|
[Steve Henson]
|
|
|
|
*) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
|
|
in the current directory if neither $RANDFILE nor $HOME was set.
|
|
RAND_file_name() in 0.9.6a returned NULL in this case. This has
|
|
caused some confusion to Windows users who haven't defined $HOME.
|
|
Thus RAND_file_name() is changed again: e_os.h can define a
|
|
DEFAULT_HOME, which will be used if $HOME is not set.
|
|
For Windows, we use "C:"; on other platforms, we still require
|
|
environment variables.
|
|
|
|
*) Move 'if (!initialized) RAND_poll()' into regions protected by
|
|
CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
|
|
having multiple threads call RAND_poll() concurrently.
|
|
[Bodo Moeller]
|
|
|
|
*) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
|
|
combination of a flag and a thread ID variable.
|
|
Otherwise while one thread is in ssleay_rand_bytes (which sets the
|
|
flag), *other* threads can enter ssleay_add_bytes without obeying
|
|
the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
|
|
that they do not hold after the first thread unsets add_do_not_lock).
|
|
[Bodo Moeller]
|
|
|
|
*) Change bctest again: '-x' expressions are not available in all
|
|
versions of 'test'.
|
|
[Bodo Moeller]
|
|
|
|
Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
|
|
|
|
*) Fix a couple of memory leaks in PKCS7_dataDecode()
|
|
[Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
|
|
|
|
*) Change Configure and Makefiles to provide EXE_EXT, which will contain
|
|
the default extension for executables, if any. Also, make the perl
|
|
scripts that use symlink() to test if it really exists and use "cp"
|
|
if it doesn't. All this made OpenSSL compilable and installable in
|
|
CygWin.
|
|
[Richard Levitte]
|
|
|
|
*) Fix for asn1_GetSequence() for indefinite length constructed data.
|
|
If SEQUENCE is length is indefinite just set c->slen to the total
|
|
amount of data available.
|
|
[Steve Henson, reported by shige@FreeBSD.org]
|
|
[This change does not apply to 0.9.7.]
|
|
|
|
*) Change bctest to avoid here-documents inside command substitution
|
|
(workaround for FreeBSD /bin/sh bug).
|
|
For compatibility with Ultrix, avoid shell functions (introduced
|
|
in the bctest version that searches along $PATH).
|
|
[Bodo Moeller]
|
|
|
|
*) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
|
|
with des_encrypt() defined on some operating systems, like Solaris
|
|
and UnixWare.
|
|
[Richard Levitte]
|
|
|
|
*) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:

|
|
Computations, J. Cryptology 14 (2001) 2, 101-119,

[Ulf Moeller]
|
|
|
|
*) MIPS assembler BIGNUM division bug fix.
|
|
[Andy Polyakov]
|
|
|
|
*) Disabled incorrect Alpha assembler code.
|
|
[Richard Levitte]
|
|
|
|
*) Fix PKCS#7 decode routines so they correctly update the length
|
|
after reading an EOC for the EXPLICIT tag.
|
|
[Steve Henson]
|
|
[This change does not apply to 0.9.7.]
|
|
|
|
*) Fix bug in PKCS#12 key generation routines. This was triggered
|
|
if a 3DES key was generated with a 0 initial byte. Include
|
|
PKCS12_BROKEN_KEYGEN compilation option to retain the old
|
|
(but broken) behaviour.
|
|
[Steve Henson]
|
|
|
|
*) Enhance bctest to search for a working bc along $PATH and print
|
|
it when found.
|
|
[Tim Rice <tim@multitalents.net> via Richard Levitte]
|
|
|
|
*) Fix memory leaks in err.c: free err_data string if necessary;
|
|
don't write to the wrong index in ERR_set_error_data.
|
|
[Bodo Moeller]
|
|
|
|
*) Implement ssl23_peek (analogous to ssl23_read), which previously
|
|
did not exist.
|
|
[Bodo Moeller]
|
|
|
|
*) Replace rdtsc with _emit statements for VC++ version 5.
|
|
[Jeremy Cooper <jeremy@baymoo.org>]
|
|
|
|
*) Make it possible to reuse SSLv2 sessions.
|
|
[Richard Levitte]
|
|
|
|
*) In copy_email() check for >= 0 as a return value for
|
|
X509_NAME_get_index_by_NID() since 0 is a valid index.
|
|
[Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
|
|
|
|
*) Avoid coredump with unsupported or invalid public keys by checking if
|
|
X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
|
|
PKCS7_verify() fails with non detached data.
|
|
[Steve Henson]
|
|
|
|
*) Don't use getenv in library functions when run as setuid/setgid.
|
|
New function OPENSSL_issetugid().
|
|
[Ulf Moeller]
|
|
|
|
*) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
|
|
due to incorrect handling of multi-threading:
|
|
|
|
1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
|
|
|
|
2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
|
|
|
|
3. Count how many times MemCheck_off() has been called so that
|
|
nested use can be treated correctly. This also avoids
|
|
inband-signalling in the previous code (which relied on the
|
|
assumption that thread ID 0 is impossible).
|
|
[Bodo Moeller]
|
|
|
|
*) Add "-rand" option also to s_client and s_server.
|
|
[Lutz Jaenicke]
|
|
|
|
*) Fix CPU detection on Irix 6.x.
|
|
[Kurt Hockenbury <khockenb@stevens-tech.edu> and
|
|
"Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
|
|
|
|
*) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
|
|
was empty.
|
|
[Steve Henson]
|
|
[This change does not apply to 0.9.7.]
|
|
|
|
*) Use the cached encoding of an X509_NAME structure rather than
|
|
copying it. This is apparently the reason for the libsafe "errors"
|
|
but the code is actually correct.
|
|
[Steve Henson]
|
|
|
|
*) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
|
|
Bleichenbacher's DSA attack.
|
|
Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
|
|
to be set and top=0 forces the highest bit to be set; top=-1 is new
|
|
and leaves the highest bit random.
|
|
[Ulf Moeller, Bodo Moeller]
|
|
|
|
*) In the NCONF_...-based implementations for CONF_... queries
|
|
(crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
|
|
a temporary CONF structure with the data component set to NULL
|
|
(which gives segmentation faults in lh_retrieve).
|
|
Instead, use NULL for the CONF pointer in CONF_get_string and
|
|
CONF_get_number (which may use environment variables) and directly
|
|
return NULL from CONF_get_section.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix potential buffer overrun for EBCDIC.
|
|
[Ulf Moeller]
|
|
|
|
*) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
|
|
keyUsage if basicConstraints absent for a CA.
|
|
[Steve Henson]
|
|
|
|
*) Make SMIME_write_PKCS7() write mail header values with a format that
|
|
is more generally accepted (no spaces before the semicolon), since
|
|
some programs can't parse those values properly otherwise. Also make
|
|
sure BIO's that break lines after each write do not create invalid
|
|
headers.
|
|
[Richard Levitte]
|
|
|
|
*) Make the CRL encoding routines work with empty SEQUENCE OF. The
|
|
macros previously used would not encode an empty SEQUENCE OF
|
|
and break the signature.
|
|
[Steve Henson]
|
|
[This change does not apply to 0.9.7.]
|
|
|
|
*) Zero the premaster secret after deriving the master secret in
|
|
DH ciphersuites.
|
|
[Steve Henson]
|
|
|
|
*) Add some EVP_add_digest_alias registrations (as found in
|
|
OpenSSL_add_all_digests()) to SSL_library_init()
|
|
aka OpenSSL_add_ssl_algorithms(). This provides improved
|
|
compatibility with peers using X.509 certificates
|
|
with unconventional AlgorithmIdentifier OIDs.
|
|
[Bodo Moeller]
|
|
|

|
[Ulf Moeller, Richard Levitte]
|
|
|
|
*) Fix 'openssl passwd -1'.
|
|
[Bodo Moeller]
|
|
|
|
*) Change PKCS12_key_gen_asc() so it can cope with non null
|
|
terminated strings whose length is passed in the passlen
|
|
parameter, for example from PEM callbacks. This was done
|
|
by adding an extra length parameter to asc2uni().
|
|
[Steve Henson, reported by <oddissey@samsung.co.kr>]
|
|
|
|
*) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
|
|
call failed, free the DSA structure.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix to uni2asc() to cope with zero length Unicode strings.
|
|
These are present in some PKCS#12 files.
|
|
[Steve Henson]
|
|
|
|
*) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
|
|
Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
|
|
when writing a 32767 byte record.
|
|
[Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
|
|
|
|
*) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
|
|
obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
|
|
|
|
(RSA objects have a reference count access to which is protected
|
|
by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
|
|
so they are meant to be shared between threads.)
|
|
[Bodo Moeller, Geoff Thorpe; original patch submitted by

*) Add a 'bctest' script that checks for some known 'bc' bugs
|
|
so that 'make test' does not abort just because 'bc' is broken.
|
|
[Bodo Moeller]
|
|
|
|
*) Store verify_result within SSL_SESSION also for client side to
|
|
avoid potential security hole. (Re-used sessions on the client side
|
|
always resulted in verify_result==X509_V_OK, not using the original
|
|
result of the server certificate verification.)
|
|
[Lutz Jaenicke]
|
|
|
|
*) Fix ssl3_pending: If the record in s->s3->rrec is not of type
|
|
SSL3_RT_APPLICATION_DATA, return 0.
|
|
Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix SSL_peek:
|
|
Both ssl2_peek and ssl3_peek, which were totally broken in earlier
|
|
releases, have been re-implemented by renaming the previous
|
|
implementations of ssl2_read and ssl3_read to ssl2_read_internal
|
|
and ssl3_read_internal, respectively, and adding 'peek' parameters
|
|
to them. The new ssl[23]_{read,peek} functions are calls to
|
|
ssl[23]_read_internal with the 'peek' flag set appropriately.
|
|
A 'peek' parameter has also been added to ssl3_read_bytes, which
|
|
does the actual work for ssl3_read_internal.
|
|
[Bodo Moeller]
|
|
|
|
*) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
|
|
the method-specific "init()" handler. Also clean up ex_data after
|
|
calling the method-specific "finish()" handler. Previously, this was
|
|
happening the other way round.
|
|
[Geoff Thorpe]
|
|
|
|
*) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
|
|
The previous value, 12, was not always sufficient for BN_mod_exp().
|
|
[Bodo Moeller]
|
|
|
|
*) Make sure that shared libraries get the internal name engine with
|
|
the full version number and not just 0. This should mark the
|
|
shared libraries as not backward compatible. Of course, this should
|
|
be changed again when we can guarantee backward binary compatibility.
|
|
[Richard Levitte]
|
|
|
|
*) Fix typo in get_cert_by_subject() in by_dir.c
|
|
[Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
|
|
|
|
*) Rework the system to generate shared libraries:
|
|
|
|
- Make note of the expected extension for the shared libraries and
|
|
if there is a need for symbolic links from for example libcrypto.so.0
|
|
to libcrypto.so.0.9.7. There is extended info in Configure for
|
|
that.
|
|
|
|
- Make as few rebuilds of the shared libraries as possible.
|
|
|
|
- Still avoid linking the OpenSSL programs with the shared libraries.
|
|
|
|
- When installing, install the shared libraries separately from the
|
|
static ones.
|
|
[Richard Levitte]
|
|
|
|
*) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
|
|
|
|
Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
|
|
and not in SSL_clear because the latter is also used by the
|
|
accept/connect functions; previously, the settings made by
|
|
SSL_set_read_ahead would be lost during the handshake.
|
|
[Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
|
|
|
|
*) Correct util/mkdef.pl to be selective about disabled algorithms.
|
|
Previously, it would create entries for disabled algorithms no
|
|
matter what.
|
|
[Richard Levitte]
|
|
|
|
*) Added several new manual pages for SSL_* function.
|
|
[Lutz Jaenicke]
|
|
|
|
Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
|
|
|
|
*) In ssl23_get_client_hello, generate an error message when faced
|
|
with an initial SSL 3.0/TLS record that is too small to contain the
|
|
first two bytes of the ClientHello message, i.e. client_version.
|
|
(Note that this is a pathologic case that probably has never happened
|
|
in real life.) The previous approach was to use the version number
|
|
from the record header as a substitute; but our protocol choice
|
|
should not depend on that one because it is not authenticated
|
|
by the Finished messages.
|
|
[Bodo Moeller]
|
|
|
|
*) More robust randomness gathering functions for Windows.
|
|
[Jeffrey Altman <jaltman@columbia.edu>]
|
|
|
|
*) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
|
|
not set then we don't setup the error code for issuer check errors
|
|
to avoid possibly overwriting other errors which the callback does
|
|
handle. If an application does set the flag then we assume it knows
|
|
what it is doing and can handle the new informational codes
|
|
appropriately.
|
|
[Steve Henson]
|
|
|
|
*) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
|
|
a general "ANY" type, as such it should be able to decode anything
|
|
including tagged types. However it didn't check the class so it would
|
|
wrongly interpret tagged types in the same way as their universal
|
|
counterpart and unknown types were just rejected. Changed so that the
|
|
tagged and unknown types are handled in the same way as a SEQUENCE:
|
|
that is the encoding is stored intact. There is also a new type
|
|
"V_ASN1_OTHER" which is used when the class is not universal, in this
|
|
case we have no idea what the actual type is so we just lump them all
|
|
together.
|
|
[Steve Henson]
|
|
|
|
*) On VMS, stdout may very well lead to a file that is written to
|
|
in a record-oriented fashion. That means that every write() will
|
|
write a separate record, which will be read separately by the
|
|
programs trying to read from it. This can be very confusing.
|
|
|
|
The solution is to put a BIO filter in the way that will buffer
|
|
text until a linefeed is reached, and then write everything a
|
|
line at a time, so every record written will be an actual line,
|
|
not chunks of lines and not (usually doesn't happen, but I've
|
|
seen it once) several lines in one record. BIO_f_linebuffer() is
|
|
the answer.
|
|
|
|
Currently, it's a VMS-only method, because that's where it has
|
|
been tested well enough.
|
|
[Richard Levitte]
|
|
|
|
*) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
|
|
it can return incorrect results.
|
|
(Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
|
|
but it was in 0.9.6-beta[12].)
|
|
[Bodo Moeller]
|
|
|
|
*) Disable the check for content being present when verifying detached
|
|
signatures in pk7_smime.c. Some versions of Netscape (wrongly)
|
|
include zero length content when signing messages.
|
|
[Steve Henson]
|
|
|
|
*) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
|
|
BIO_ctrl (for BIO pairs).
|
|
[Bodo Möller]
|
|
|
|
*) Add DSO method for VMS.
|
|
[Richard Levitte]
|
|
|
|
*) Bug fix: Montgomery multiplication could produce results with the
|
|
wrong sign.
|
|
[Ulf Möller]
|
|
|
|
*) Add RPM specification openssl.spec and modify it to build three
|
|
packages. The default package contains applications, application
|
|
documentation and run-time libraries. The devel package contains
|
|
include files, static libraries and function documentation. The
|
|
doc package contains the contents of the doc directory. The original
|
|
openssl.spec was provided by Damien Miller <djm@mindrot.org>.
|
|
[Richard Levitte]
|
|
|
|
*) Add a large number of documentation files for many SSL routines.
|
|
[Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
|
|
|
|
*) Add a configuration entry for Sony News 4.
|
|
[NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
|
|
|
|
*) Don't set the two most significant bits to one when generating a
|
|
random number < q in the DSA library.
|
|
[Ulf Möller]
|
|
|
|
*) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
|
|
behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
|
|
the underlying transport is blocking) if a handshake took place.
|
|
(The default behaviour is needed by applications such as s_client
|
|
and s_server that use select() to determine when to use SSL_read;
|
|
but for applications that know in advance when to expect data, it
|
|
just makes things more complicated.)
|
|
[Bodo Moeller]
|
|
|
|
*) Add RAND_egd_bytes(), which gives control over the number of bytes read
|
|
from EGD.
|
|
[Ben Laurie]
|
|
|
|
*) Add a few more EBCDIC conditionals that make `req' and `x509'
|
|
work better on such systems.
|
|
[Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
|
|
|
|
*) Add two demo programs for PKCS12_parse() and PKCS12_create().
|
|
Update PKCS12_parse() so it copies the friendlyName and the
|
|
keyid to the certificates aux info.
|
|
[Steve Henson]
|
|
|
|
*) Fix bug in PKCS7_verify() which caused an infinite loop
|
|
if there was more than one signature.
|
|
[Sven Uszpelkat <su@celocom.de>]
|
|
|
|
*) Major change in util/mkdef.pl to include extra information
|
|
about each symbol, as well as presenting variables as well
|
|
as functions. This change means that there's n more need
|
|
to rebuild the .num files when some algorithms are excluded.
|
|
[Richard Levitte]
|
|
|
|
*) Allow the verify time to be set by an application,
|
|
rather than always using the current time.
|
|
[Steve Henson]
|
|
|
|
*) Phase 2 verify code reorganisation. The certificate
|
|
verify code now looks up an issuer certificate by a
|
|
number of criteria: subject name, authority key id
|
|
and key usage. It also verifies self signed certificates
|
|
by the same criteria. The main comparison function is
|
|
X509_check_issued() which performs these checks.
|
|
|
|
Lot of changes were necessary in order to support this
|
|
without completely rewriting the lookup code.
|
|
|
|
Authority and subject key identifier are now cached.
|
|
|
|
The LHASH 'certs' is X509_STORE has now been replaced
|
|
by a STACK_OF(X509_OBJECT). This is mainly because an
|
|
LHASH can't store or retrieve multiple objects with
|
|
the same hash value.
|
|
|
|
As a result various functions (which were all internal
|
|
use only) have changed to handle the new X509_STORE
|
|
structure. This will break anything that messed round
|
|
with X509_STORE internally.
|
|
|
|
The functions X509_STORE_add_cert() now checks for an
|
|
exact match, rather than just subject name.
|
|
|
|
The X509_STORE API doesn't directly support the retrieval
|
|
of multiple certificates matching a given criteria, however
|
|
this can be worked round by performing a lookup first
|
|
(which will fill the cache with candidate certificates)
|
|
and then examining the cache for matches. This is probably
|
|
the best we can do without throwing out X509_LOOKUP
|
|
entirely (maybe later...).
|
|
|
|
The X509_VERIFY_CTX structure has been enhanced considerably.
|
|
|
|
All certificate lookup operations now go via a get_issuer()
|
|
callback. Although this currently uses an X509_STORE it
|
|
can be replaced by custom lookups. This is a simple way
|
|
to bypass the X509_STORE hackery necessary to make this
|
|
work and makes it possible to use more efficient techniques
|
|
in future. A very simple version which uses a simple
|
|
STACK for its trusted certificate store is also provided
|
|
using X509_STORE_CTX_trusted_stack().
|
|
|
|
The verify_cb() and verify() callbacks now have equivalents
|
|
in the X509_STORE_CTX structure.
|
|
|
|
X509_STORE_CTX also has a 'flags' field which can be used
|
|
to customise the verify behaviour.
|
|
[Steve Henson]
|
|
|
|
*) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
|
|
excludes S/MIME capabilities.
|
|
[Steve Henson]
|
|
|
|
*) When a certificate request is read in keep a copy of the
|
|
original encoding of the signed data and use it when outputting
|
|
again. Signatures then use the original encoding rather than
|
|
a decoded, encoded version which may cause problems if the
|
|
request is improperly encoded.
|
|
[Steve Henson]
|
|
|
|
*) For consistency with other BIO_puts implementations, call
|
|
buffer_write(b, ...) directly in buffer_puts instead of calling
|
|
BIO_write(b, ...).
|
|
|
|
In BIO_puts, increment b->num_write as in BIO_write.
|
|
[Peter.Sylvester@EdelWeb.fr]
|
|
|
|
*) Fix BN_mul_word for the case where the word is 0. (We have to use
|
|
BN_zero, we may not return a BIGNUM with an array consisting of
|
|
words set to zero.)
|
|
[Bodo Moeller]
|
|
|
|
*) Avoid calling abort() from within the library when problems are
|
|
detected, except if preprocessor symbols have been defined
|
|
(such as REF_CHECK, BN_DEBUG etc.).
|
|
[Bodo Moeller]
|
|
|
|
*) New openssl application 'rsautl'. This utility can be
|
|
used for low level RSA operations. DER public key
|
|
BIO/fp routines also added.
|
|
[Steve Henson]
|
|
|
|
*) New Configure entry and patches for compiling on QNX 4.
|
|
[Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
|
|
|
|
*) A demo state-machine implementation was sponsored by
|
|
Nuron (http://www.nuron.com/) and is now available in
|
|
demos/state_machine.
|
|
[Ben Laurie]
|
|
|
|
*) New options added to the 'dgst' utility for signature
|
|
generation and verification.
|
|
[Steve Henson]
|
|
|
|
*) Unrecognized PKCS#7 content types are now handled via a
|
|
catch all ASN1_TYPE structure. This allows unsupported
|
|
types to be stored as a "blob" and an application can
|
|
encode and decode it manually.
|
|
[Steve Henson]
|
|
|
|
*) Fix various signed/unsigned issues to make a_strex.c
|
|
compile under VC++.
|
|
[Oscar Jacobsson <oscar.jacobsson@celocom.com>]
|
|
|
|
*) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
|
|
length if passed a buffer. ASN1_INTEGER_to_BN failed
|
|
if passed a NULL BN and its argument was negative.
|
|
[Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
|
|
|
|
*) Modification to PKCS#7 encoding routines to output definite
|
|
length encoding. Since currently the whole structures are in
|
|
memory there's not real point in using indefinite length
|
|
constructed encoding. However if OpenSSL is compiled with
|
|
the flag PKCS7_INDEFINITE_ENCODING the old form is used.
|
|
[Steve Henson]
|
|
|
|
*) Added BIO_vprintf() and BIO_vsnprintf().
|
|
[Richard Levitte]
|
|
|
|
*) Added more prefixes to parse for in the strings written
|
|
through a logging bio, to cover all the levels that are available
|
|
through syslog. The prefixes are now:
|
|
|
|
PANIC, EMERG, EMR => LOG_EMERG
|
|
ALERT, ALR => LOG_ALERT
|
|
CRIT, CRI => LOG_CRIT
|
|
ERROR, ERR => LOG_ERR
|
|
WARNING, WARN, WAR => LOG_WARNING
|
|
NOTICE, NOTE, NOT => LOG_NOTICE
|
|
INFO, INF => LOG_INFO
|
|
DEBUG, DBG => LOG_DEBUG
|
|
|
|
and as before, if none of those prefixes are present at the
|
|
beginning of the string, LOG_ERR is chosen.
|
|
|
|
On Win32, the LOG_* levels are mapped according to this:
|
|
|
|
LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
|
|
LOG_WARNING => EVENTLOG_WARNING_TYPE
|
|
LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
|
|
|
|
[Richard Levitte]
|
|
|
|
*) Made it possible to reconfigure with just the configuration
|
|
argument "reconf" or "reconfigure". The command line arguments
|
|
are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
|
|
and are retrieved from there when reconfiguring.
|
|
[Richard Levitte]
|
|
|
|
*) MD4 implemented.
|
|
[Assar Westerlund <assar@sics.se>, Richard Levitte]
|
|
|
|
*) Add the arguments -CAfile and -CApath to the pkcs12 utility.
|
|
[Richard Levitte]
|
|
|
|
*) The obj_dat.pl script was messing up the sorting of object
|
|
names. The reason was that it compared the quoted version
|
|
of strings as a result "OCSP" > "OCSP Signing" because
|
|
" > SPACE. Changed script to store unquoted versions of
|
|
names and add quotes on output. It was also omitting some
|
|
names from the lookup table if they were given a default
|
|
value (that is if SN is missing it is given the same
|
|
value as LN and vice versa), these are now added on the
|
|
grounds that if an object has a name we should be able to
|
|
look it up. Finally added warning output when duplicate
|
|
short or long names are found.
|
|
[Steve Henson]
|
|
|
|
*) Changes needed for Tandem NSK.
|
|
[Scott Uroff <scott@xypro.com>]
|
|
|
|
*) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
|
|
RSA_padding_check_SSLv23(), special padding was never detected
|
|
and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
|
|
version rollback attacks was not effective.
|
|
|
|
In s23_clnt.c, don't use special rollback-attack detection padding
|
|
(RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
|
|
client; similarly, in s23_srvr.c, don't do the rollback check if
|
|
SSL 2.0 is the only protocol enabled in the server.
|
|
[Bodo Moeller]
|
|
|
|
*) Make it possible to get hexdumps of unprintable data with 'openssl
|
|
asn1parse'. By implication, the functions ASN1_parse_dump() and
|
|
BIO_dump_indent() are added.
|
|
[Richard Levitte]
|
|
|
|
*) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
|
|
these print out strings and name structures based on various
|
|
flags including RFC2253 support and proper handling of
|
|
multibyte characters. Added options to the 'x509' utility
|
|
to allow the various flags to be set.
|
|
[Steve Henson]
|
|
|
|
*) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
|
|
Also change the functions X509_cmp_current_time() and
|
|
X509_gmtime_adj() work with an ASN1_TIME structure,
|
|
this will enable certificates using GeneralizedTime in validity
|
|
dates to be checked.
|
|
[Steve Henson]
|
|
|
|
*) Make the NEG_PUBKEY_BUG code (which tolerates invalid
|
|
negative public key encodings) on by default,
|
|
NO_NEG_PUBKEY_BUG can be set to disable it.
|
|
[Steve Henson]
|
|
|
|
*) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
|
|
content octets. An i2c_ASN1_OBJECT is unnecessary because
|
|
the encoding can be trivially obtained from the structure.
|
|
[Steve Henson]
|
|
|
|
*) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
|
|
not read locks (CRYPTO_r_[un]lock).
|
|
[Bodo Moeller]
|
|
|
|
*) A first attempt at creating official support for shared
|
|
libraries through configuration. I've kept it so the
|
|
default is static libraries only, and the OpenSSL programs
|
|
are always statically linked for now, but there are
|
|
preparations for dynamic linking in place.
|
|
This has been tested on Linux and Tru64.
|
|
[Richard Levitte]
|
|
|
|
*) Randomness polling function for Win9x, as described in:
|
|
Peter Gutmann, Software Generation of Practically Strong
|
|
Random Numbers.
|
|
[Ulf Möller]
|
|
|
|
*) Fix so PRNG is seeded in req if using an already existing
|
|
DSA key.
|
|
[Steve Henson]
|
|
|
|
*) New options to smime application. -inform and -outform
|
|
allow alternative formats for the S/MIME message including
|
|
PEM and DER. The -content option allows the content to be
|
|
specified separately. This should allow things like Netscape
|
|
form signing output easier to verify.
|
|
[Steve Henson]
|
|
|
|
*) Fix the ASN1 encoding of tags using the 'long form'.
|
|
[Steve Henson]
|
|
|
|
*) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
|
|
STRING types. These convert content octets to and from the
|
|
underlying type. The actual tag and length octets are
|
|
already assumed to have been read in and checked. These
|
|
are needed because all other string types have virtually
|
|
identical handling apart from the tag. By having versions
|
|
of the ASN1 functions that just operate on content octets
|
|
IMPLICIT tagging can be handled properly. It also allows
|
|
the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
|
|
and ASN1_INTEGER are identical apart from the tag.
|
|
[Steve Henson]
|
|
|
|
*) Change the handling of OID objects as follows:
|
|
|
|
- New object identifiers are inserted in objects.txt, following
|
|
the syntax given in objects.README.
|
|
- objects.pl is used to process obj_mac.num and create a new
|
|
obj_mac.h.
|
|
- obj_dat.pl is used to create a new obj_dat.h, using the data in
|
|
obj_mac.h.
|
|
|
|
This is currently kind of a hack, and the perl code in objects.pl
|
|
isn't very elegant, but it works as I intended. The simplest way
|
|
to check that it worked correctly is to look in obj_dat.h and
|
|
check the array nid_objs and make sure the objects haven't moved
|
|
around (this is important!). Additions are OK, as well as
|
|
consistent name changes.
|
|
[Richard Levitte]
|
|
|
|
*) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
|
|
[Bodo Moeller]
|
|
|
|
*) Addition of the command line parameter '-rand file' to 'openssl req'.
|
|
The given file adds to whatever has already been seeded into the
|
|
random pool through the RANDFILE configuration file option or
|
|
environment variable, or the default random state file.
|
|
[Richard Levitte]
|
|
|
|
*) mkstack.pl now sorts each macro group into lexical order.
|
|
Previously the output order depended on the order the files
|
|
appeared in the directory, resulting in needless rewriting
|
|
of safestack.h .
|
|
[Steve Henson]
|
|
|
|
*) Patches to make OpenSSL compile under Win32 again. Mostly
|
|
work arounds for the VC++ problem that it treats func() as
|
|
func(void). Also stripped out the parts of mkdef.pl that
|
|
added extra typesafe functions: these no longer exist.
|
|
[Steve Henson]
|
|
|
|
*) Reorganisation of the stack code. The macros are now all
|
|
collected in safestack.h . Each macro is defined in terms of
|
|
a "stack macro" of the form SKM_<name>(type, a, b). The
|
|
DEBUG_SAFESTACK is now handled in terms of function casts,
|
|
this has the advantage of retaining type safety without the
|
|
use of additional functions. If DEBUG_SAFESTACK is not defined
|
|
then the non typesafe macros are used instead. Also modified the
|
|
mkstack.pl script to handle the new form. Needs testing to see
|
|
if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
|
|
the default if no major problems. Similar behaviour for ASN1_SET_OF
|
|
and PKCS12_STACK_OF.
|
|
[Steve Henson]
|
|
|
|
*) When some versions of IIS use the 'NET' form of private key the
|
|
key derivation algorithm is different. Normally MD5(password) is
|
|
used as a 128 bit RC4 key. In the modified case
|
|
MD5(MD5(password) + "SGCKEYSALT") is used instead. Added some
|
|
new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
|
|
as the old Netscape_RSA functions except they have an additional
|
|
'sgckey' parameter which uses the modified algorithm. Also added
|
|
an -sgckey command line option to the rsa utility. Thanks to
|
|
Adrian Peck <bertie@ncipher.com> for posting details of the modified
|
|
algorithm to openssl-dev.
|
|
[Steve Henson]
|
|
|
|
*) The evp_local.h macros were using 'c.##kname' which resulted in
|
|
invalid expansion on some systems (SCO 5.0.5 for example).
|
|
Corrected to 'c.kname'.
|
|
[Phillip Porch <root@theporch.com>]
|
|
|
|
*) New X509_get1_email() and X509_REQ_get1_email() functions that return
|
|
a STACK of email addresses from a certificate or request, these look
|
|
in the subject name and the subject alternative name extensions and
|
|
omit any duplicate addresses.
|
|
[Steve Henson]
|
|
|
|
*) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
|
|
This makes DSA verification about 2 % faster.
|
|
[Bodo Moeller]
|
|
|
|
*) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
|
|
(meaning that now 2^5 values will be precomputed, which is only 4 KB
|
|
plus overhead for 1024 bit moduli).
|
|
This makes exponentiations about 0.5 % faster for 1024 bit
|
|
exponents (as measured by "openssl speed rsa2048").
|
|
[Bodo Moeller]
|
|
|
|
*) Rename memory handling macros to avoid conflicts with other
|
|
software:
|
|
Malloc => OPENSSL_malloc
|
|
Malloc_locked => OPENSSL_malloc_locked
|
|
Realloc => OPENSSL_realloc
|
|
Free => OPENSSL_free
|
|
[Richard Levitte]
|
|
|
|
*) New function BN_mod_exp_mont_word for small bases (roughly 15%
|
|
faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
|
|
[Bodo Moeller]
|
|
|
|
*) CygWin32 support.
|
|
[John Jarvie <jjarvie@newsguy.com>]
|
|
|
|
*) The type-safe stack code has been rejigged. It is now only compiled
|
|
in when OpenSSL is configured with the DEBUG_SAFESTACK option and
|
|
by default all type-specific stack functions are "#define"d back to
|
|
standard stack functions. This results in more streamlined output
|
|
but retains the type-safety checking possibilities of the original
|
|
approach.
|
|
[Geoff Thorpe]
|
|
|
|
*) The STACK code has been cleaned up, and certain type declarations
|
|
that didn't make a lot of sense have been brought in line. This has
|
|
also involved a cleanup of sorts in safestack.h to more correctly
|
|
map type-safe stack functions onto their plain stack counterparts.
|
|
This work has also resulted in a variety of "const"ifications of
|
|
lots of the code, especially "_cmp" operations which should normally
|
|
be prototyped with "const" parameters anyway.
|
|
[Geoff Thorpe]
|
|
|
|
*) When generating bytes for the first time in md_rand.c, 'stir the pool'
|
|
by seeding with STATE_SIZE dummy bytes (with zero entropy count).
|
|
(The PRNG state consists of two parts, the large pool 'state' and 'md',
|
|
where all of 'md' is used each time the PRNG is used, but 'state'
|
|
is used only indexed by a cyclic counter. As entropy may not be
|
|
well distributed from the beginning, 'md' is important as a
|
|
chaining variable. However, the output function chains only half
|
|
of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
|
|
all of 'md', and seeding with STATE_SIZE dummy bytes will result
|
|
in all of 'state' being rewritten, with the new values depending
|
|
on virtually all of 'md'. This overcomes the 80 bit limitation.)
|
|
[Bodo Moeller]
|
|
|
|
*) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
|
|
the handshake is continued after ssl_verify_cert_chain();
|
|
otherwise, if SSL_VERIFY_NONE is set, remaining error codes
|
|
can lead to 'unexplainable' connection aborts later.
|
|
[Bodo Moeller; problem tracked down by Lutz Jaenicke]
|
|
|
|
*) Major EVP API cipher revision.
|
|
Add hooks for extra EVP features. This allows various cipher
|
|
parameters to be set in the EVP interface. Support added for variable
|
|
key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
|
|
setting of RC2 and RC5 parameters.
|
|
|
|
Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
|
|
ciphers.
|
|
|
|
Remove lots of duplicated code from the EVP library. For example *every*
|
|
cipher init() function handles the 'iv' in the same way according to the
|
|
cipher mode. They also all do nothing if the 'key' parameter is NULL and
|
|
for CFB and OFB modes they zero ctx->num.
|
|
|
|
New functionality allows removal of S/MIME code RC2 hack.
|
|
|
|
Most of the routines have the same form and so can be declared in terms
|
|
of macros.
|
|
|
|
By shifting this to the top level EVP_CipherInit() it can be removed from
|
|
all individual ciphers. If the cipher wants to handle IVs or keys
|
|
differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
|
|
flags.
|
|
|
|
Change lots of functions like EVP_EncryptUpdate() to now return a
|
|
value: although software versions of the algorithms cannot fail
|
|
any installed hardware versions can.
|
|
[Steve Henson]
|
|
|
|
*) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
|
|
this option is set, tolerate broken clients that send the negotiated
|
|
protocol version number instead of the requested protocol version
|
|
number.
|
|
[Bodo Moeller]
|
|
|
|
*) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
|
|
i.e. non-zero for export ciphersuites, zero otherwise.
|
|
Previous versions had this flag inverted, inconsistent with
|
|
rsa_tmp_cb (..._TMP_RSA_CB).
|
|
[Bodo Moeller; problem reported by Amit Chopra]
|
|
|
|
*) Add missing DSA library text string. Work around for some IIS
|
|
key files with invalid SEQUENCE encoding.
|
|
[Steve Henson]
|
|
|
|
*) Add a document (doc/standards.txt) that list all kinds of standards
|
|
and so on that are implemented in OpenSSL.
|
|
[Richard Levitte]
|
|
|
|
*) Enhance c_rehash script. Old version would mishandle certificates
|
|
with the same subject name hash and wouldn't handle CRLs at all.
|
|
Added -fingerprint option to crl utility, to support new c_rehash
|
|
features.
|
|
[Steve Henson]
|
|
|
|
*) Eliminate non-ANSI declarations in crypto.h and stack.h.
|
|
[Ulf Möller]
|
|
|
|
*) Fix for SSL server purpose checking. Server checking was
|
|
rejecting certificates which had extended key usage present
|
|
but no ssl client purpose.
|
|
[Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
|
|
|
|
*) Make PKCS#12 code work with no password. The PKCS#12 spec
|
|
is a little unclear about how a blank password is handled.
|
|
Since the password in encoded as a BMPString with terminating
|
|
double NULL a zero length password would end up as just the
|
|
double NULL. However no password at all is different and is
|
|
handled differently in the PKCS#12 key generation code. NS
|
|
treats a blank password as zero length. MSIE treats it as no
|
|
password on export: but it will try both on import. We now do
|
|
the same: PKCS12_parse() tries zero length and no password if
|
|
the password is set to "" or NULL (NULL is now a valid password:
|
|
it wasn't before) as does the pkcs12 application.
|
|
[Steve Henson]
|
|
|
|
*) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
|
|
perror when PEM_read_bio_X509_REQ fails, the error message must
|
|
be obtained from the error queue.
|
|
[Bodo Moeller]
|
|
|
|
*) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
|
|
it in ERR_remove_state if appropriate, and change ERR_get_state
|
|
accordingly to avoid race conditions (this is necessary because
|
|
thread_hash is no longer constant once set).
|
|
[Bodo Moeller]
|
|
|
|
*) Bugfix for linux-elf makefile.one.
|
|
[Ulf Möller]
|
|
|
|
*) RSA_get_default_method() will now cause a default
|
|
RSA_METHOD to be chosen if one doesn't exist already.
|
|
Previously this was only set during a call to RSA_new()
|
|
or RSA_new_method(NULL) meaning it was possible for
|
|
RSA_get_default_method() to return NULL.
|
|
[Geoff Thorpe]
|
|
|
|
*) Added native name translation to the existing DSO code
|
|
that will convert (if the flag to do so is set) filenames
|
|
that are sufficiently small and have no path information
|
|
into a canonical native form. Eg. "blah" converted to
|
|
"libblah.so" or "blah.dll" etc.
|
|
[Geoff Thorpe]
|
|
|
|
*) New function ERR_error_string_n(e, buf, len) which is like
|
|
ERR_error_string(e, buf), but writes at most 'len' bytes
|
|
including the 0 terminator. For ERR_error_string_n, 'buf'
|
|
may not be NULL.
|
|
[Damien Miller <djm@mindrot.org>, Bodo Moeller]
|
|
|
|
*) CONF library reworked to become more general. A new CONF
|
|
configuration file reader "class" is implemented as well as a
|
|
new functions (NCONF_*, for "New CONF") to handle it. The now
|
|
old CONF_* functions are still there, but are reimplemented to
|
|
work in terms of the new functions. Also, a set of functions
|
|
to handle the internal storage of the configuration data is
|
|
provided to make it easier to write new configuration file
|
|
reader "classes" (I can definitely see something reading a
|
|
configuration file in XML format, for example), called _CONF_*,
|
|
or "the configuration storage API"...
|
|
|
|
The new configuration file reading functions are:
|
|
|
|
NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
|
|
NCONF_get_section, NCONF_get_string, NCONF_get_numbre
|
|
|
|
NCONF_default, NCONF_WIN32
|
|
|
|
NCONF_dump_fp, NCONF_dump_bio
|
|
|
|
NCONF_default and NCONF_WIN32 are method (or "class") choosers,
|
|
NCONF_new creates a new CONF object. This works in the same way
|
|
as other interfaces in OpenSSL, like the BIO interface.
|
|
NCONF_dump_* dump the internal storage of the configuration file,
|
|
which is useful for debugging. All other functions take the same
|
|
arguments as the old CONF_* functions with the exception of the
|
|
first that must be a `CONF *' instead of a `LHASH *'.
|
|
|
|
To make it easier to use the new classes with the old CONF_* functions,
|
|
the function CONF_set_default_method is provided.
|
|
[Richard Levitte]
|
|
|
|
*) Add '-tls1' option to 'openssl ciphers', which was already
|
|
mentioned in the documentation but had not been implemented.
|
|
(This option is not yet really useful because even the additional
|
|
experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
|
|
[Bodo Moeller]
|
|
|
|
*) Initial DSO code added into libcrypto for letting OpenSSL (and
|
|
OpenSSL-based applications) load shared libraries and bind to
|
|
them in a portable way.
|
|
[Geoff Thorpe, with contributions from Richard Levitte]
|
|
|
|
Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
|
|
|
|
*) Make sure _lrotl and _lrotr are only used with MSVC.
|
|
|
|
*) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
|
|
(the default implementation of RAND_status).
|
|
|
|
*) Rename openssl x509 option '-crlext', which was added in 0.9.5,
|
|
to '-clrext' (= clear extensions), as intended and documented.
|
|
[Bodo Moeller; inconsistency pointed out by Michael Attili
|
|
<attili@amaxo.com>]
|
|
|
|
*) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
|
|
was larger than the MD block size.
|
|
[Steve Henson, pointed out by Yost William <YostW@tce.com>]
|
|
|
|
*) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
|
|
fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
|
|
using the passed key: if the passed key was a private key the result
|
|
of X509_print(), for example, would be to print out all the private key
|
|
components.
|
|
[Steve Henson]
|
|
|
|
*) des_quad_cksum() byte order bug fix.
|
|
[Ulf Möller, using the problem description in krb4-0.9.7, where
|
|
the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
|
|
|
|
*) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
|
|
discouraged.
|
|
[Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
|
|
|
|
*) For easily testing in shell scripts whether some command
|
|
'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
|
|
returns with exit code 0 iff no command of the given name is available.
|
|
'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
|
|
the output goes to stdout and nothing is printed to stderr.
|
|
Additional arguments are always ignored.
|
|
|
|
Since for each cipher there is a command of the same name,
|
|
the 'no-cipher' compilation switches can be tested this way.
|
|
|
|
('openssl no-XXX' is not able to detect pseudo-commands such
|
|
as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
|
|
[Bodo Moeller]
|
|
|
|
*) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
|
|
[Bodo Moeller]
|
|
|
|
*) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
|
|
is set; it will be thrown away anyway because each handshake creates
|
|
its own key.
|
|
ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
|
|
to parameters -- in previous versions (since OpenSSL 0.9.3) the
|
|
'default key' from SSL_CTX_set_tmp_dh would always be lost, meaning
|
|
you effectively got SSL_OP_SINGLE_DH_USE when using this macro.
|
|
[Bodo Moeller]
|
|
|
|
*) New s_client option -ign_eof: EOF at stdin is ignored, and
|
|
'Q' and 'R' lose their special meanings (quit/renegotiate).
|
|
This is part of what -quiet does; unlike -quiet, -ign_eof
|
|
does not suppress any output.
|
|
[Richard Levitte]
|
|
|
|
*) Add compatibility options to the purpose and trust code. The
|
|
purpose X509_PURPOSE_ANY is "any purpose" which automatically
|
|
accepts a certificate or CA, this was the previous behaviour,
|
|
with all the associated security issues.
|
|
|
|
X509_TRUST_COMPAT is the old trust behaviour: only and
|
|
automatically trust self signed roots in certificate store. A
|
|
new trust setting X509_TRUST_DEFAULT is used to specify that
|
|
a purpose has no associated trust setting and it should instead
|
|
use the value in the default purpose.
|
|
[Steve Henson]
|
|
|
|
*) Fix the PKCS#8 DSA private key code so it decodes keys again
|
|
and fix a memory leak.
|
|
[Steve Henson]
|
|
|
|
*) In util/mkerr.pl (which implements 'make errors'), preserve
|
|
reason strings from the previous version of the .c file, as
|
|
the default to have only downcase letters (and digits) in
|
|
automatically generated reasons codes is not always appropriate.
|
|
[Bodo Moeller]
|
|
|
|
*) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
|
|
using strerror. Previously, ERR_reason_error_string() returned
|
|
library names as reason strings for SYSerr; but SYSerr is a special
|
|
case where small numbers are errno values, not library numbers.
|
|
[Bodo Moeller]
|
|
|
|
*) Add '-dsaparam' option to 'openssl dhparam' application. This
|
|
converts DSA parameters into DH parameters. (When creating parameters,
|
|
DSA_generate_parameters is used.)
|
|
[Bodo Moeller]
|
|
|
|
*) Include 'length' (recommended exponent length) in C code generated
|
|
by 'openssl dhparam -C'.
|
|
[Bodo Moeller]
|
|
|
|
*) The second argument to set_label in perlasm was already being used
|
|
so couldn't be used as a "file scope" flag. Moved to third argument
|
|
which was free.
|
|
[Steve Henson]
|
|
|
|
*) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
|
|
instead of RAND_bytes for encryption IVs and salts.
|
|
[Bodo Moeller]
|
|
|
|
*) Include RAND_status() into RAND_METHOD instead of implementing
|
|
it only for md_rand.c Otherwise replacing the PRNG by calling
|
|
RAND_set_rand_method would be impossible.
|
|
[Bodo Moeller]
|
|
|
|
*) Don't let DSA_generate_key() enter an infinite loop if the random
|
|
number generation fails.
|
|
[Bodo Moeller]
|
|
|
|
*) New 'rand' application for creating pseudo-random output.
|
|
[Bodo Moeller]
|
|
|
|
*) Added configuration support for Linux/IA64
|
|
[Rolf Haberrecker <rolf@suse.de>]
|
|
|
|
*) Assembler module support for Mingw32.
|
|
[Ulf Möller]
|
|
|
|
*) Shared library support for HPUX (in shlib/).
|
|
[Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
|
|
|
|
*) Shared library support for Solaris gcc.
|
|
[Lutz Behnke <behnke@trustcenter.de>]
|
|
|
|
Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
|
|
|
|
*) PKCS7_encrypt() was adding text MIME headers twice because they
|
|
were added manually and by SMIME_crlf_copy().
|
|
[Steve Henson]
|
|
|
|
*) In bntest.c don't call BN_rand with zero bits argument.
|
|
[Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
|
|
|
|
*) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
|
|
case was implemented. This caused BN_div_recp() to fail occasionally.
|
|
[Ulf Möller]
|
|
|
|
*) Add an optional second argument to the set_label() in the perl
|
|
assembly language builder. If this argument exists and is set
|
|
to 1 it signals that the assembler should use a symbol whose
|
|
scope is the entire file, not just the current function. This
|
|
is needed with MASM which uses the format label:: for this scope.
|
|
[Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
|
|
|
|
*) Change the ASN1 types so they are typedefs by default. Before
|
|
almost all types were #define'd to ASN1_STRING which was causing
|
|
STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
|
|
for example.
|
|
[Steve Henson]
|
|
|
|
*) Change names of new functions to the new get1/get0 naming
|
|
convention: After 'get1', the caller owns a reference count
|
|
and has to call ..._free; 'get0' returns a pointer to some
|
|
data structure without incrementing reference counters.
|
|
(Some of the existing 'get' functions increment a reference
|
|
counter, some don't.)
|
|
Similarly, 'set1' and 'add1' functions increase reference
|
|
counters or duplicate objects.
|
|
[Steve Henson]
|
|
|
|
*) Allow for the possibility of temp RSA key generation failure:
|
|
the code used to assume it always worked and crashed on failure.
|
|
[Steve Henson]
|
|
|
|
*) Fix potential buffer overrun problem in BIO_printf().
|
|
[Ulf Möller, using public domain code by Patrick Powell; problem
|
|
pointed out by David Sacerdote <das33@cornell.edu>]
|
|
|
|
*) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
|
|
RAND_egd() and RAND_status(). In the command line application,
|
|
the EGD socket can be specified like a seed file using RANDFILE
|
|
or -rand.
|
|
[Ulf Möller]
|
|
|
|
*) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
|
|
Some CAs (e.g. Verisign) distribute certificates in this form.
|
|
[Steve Henson]
|
|
|
|
*) Remove the SSL_ALLOW_ADH compile option and set the default cipher
|
|
list to exclude them. This means that no special compilation option
|
|
is needed to use anonymous DH: it just needs to be included in the
|
|
cipher list.
|
|
[Steve Henson]
|
|
|
|
*) Change the EVP_MD_CTX_type macro so its meaning consistent with
|
|
EVP_MD_type. The old functionality is available in a new macro called
|
|
EVP_MD_md(). Change code that uses it and update docs.
|
|
[Steve Henson]
|
|
|
|
*) ..._ctrl functions now have corresponding ..._callback_ctrl functions
|
|
where the 'void *' argument is replaced by a function pointer argument.
|
|
Previously 'void *' was abused to point to functions, which works on
|
|
many platforms, but is not correct. As these functions are usually
|
|
called by macros defined in OpenSSL header files, most source code
|
|
should work without changes.
|
|
[Richard Levitte]
|
|
|
|
*) <openssl/opensslconf.h> (which is created by Configure) now contains
|
|
sections with information on -D... compiler switches used for
|
|
compiling the library so that applications can see them. To enable
|
|
one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
|
|
must be defined. E.g.,
|
|
#define OPENSSL_ALGORITHM_DEFINES
|
|
#include <openssl/opensslconf.h>
|
|
defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
|
|
[Richard Levitte, Ulf and Bodo Möller]
|
|
|
|
*) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
|
|
record layer.
|
|
[Bodo Moeller]
|
|
|
|
*) Change the 'other' type in certificate aux info to a STACK_OF
|
|
X509_ALGOR. Although not an AlgorithmIdentifier as such it has
|
|
the required ASN1 format: arbitrary types determined by an OID.
|
|
[Steve Henson]
|
|
|
|
*) Add some PEM_write_X509_REQ_NEW() functions and a command line
|
|
argument to 'req'. This is not because the function is newer or
|
|
better than others it just uses the work 'NEW' in the certificate
|
|
request header lines. Some software needs this.
|
|
[Steve Henson]
|
|
|
|
*) Reorganise password command line arguments: now passwords can be
|
|
obtained from various sources. Delete the PEM_cb function and make
|
|
it the default behaviour: i.e. if the callback is NULL and the
|
|
usrdata argument is not NULL interpret it as a null terminated pass
|
|
phrase. If usrdata and the callback are NULL then the pass phrase
|
|
is prompted for as usual.
|
|
[Steve Henson]
|
|
|
|
*) Add support for the Compaq Atalla crypto accelerator. If it is installed,
|
|
the support is automatically enabled. The resulting binaries will
|
|
autodetect the card and use it if present.
|
|
[Ben Laurie and Compaq Inc.]
|
|
|
|
*) Work around for Netscape hang bug. This sends certificate request
|
|
and server done in one record. Since this is perfectly legal in the
|
|
SSL/TLS protocol it isn't a "bug" option and is on by default. See
|
|
the bugs/SSLv3 entry for more info.
|
|
[Steve Henson]
|
|
|
|
*) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
|
|
[Andy Polyakov]
|
|
|
|
*) Add -rand argument to smime and pkcs12 applications and read/write
|
|
of seed file.
|
|
[Steve Henson]
|
|
|
|
*) New 'passwd' tool for crypt(3) and apr1 password hashes.
|
|
[Bodo Moeller]
|
|
|
|
*) Add command line password options to the remaining applications.
|
|
[Steve Henson]
|
|
|
|
*) Bug fix for BN_div_recp() for numerators with an even number of
|
|
bits.
|
|
[Ulf Möller]
|
|
|
|
*) More tests in bntest.c, and changed test_bn output.
|
|
[Ulf Möller]
|
|
|
|
*) ./config recognizes MacOS X now.
|
|
[Andy Polyakov]
|
|
|
|
*) Bug fix for BN_div() when the first words of num and divisor are
|
|
equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
|
|
[Ulf Möller]
|
|
|
|
*) Add support for various broken PKCS#8 formats, and command line
|
|
options to produce them.
|
|
[Steve Henson]
|
|
|
|
*) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
|
|
get temporary BIGNUMs from a BN_CTX.
|
|
[Ulf Möller]
|
|
|
|
*) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
|
|
for p == 0.
|
|
[Ulf Möller]
|
|
|
|
*) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
|
|
include a #define from the old name to the new. The original intent
|
|
was that statically linked binaries could for example just call
|
|
SSLeay_add_all_ciphers() to just add ciphers to the table and not
|
|
link with digests. This never worked because SSLeay_add_all_digests()
|
|
and SSLeay_add_all_ciphers() were in the same source file so calling
|
|
one would link with the other. They are now in separate source files.
|
|
[Steve Henson]
|
|
|
|
*) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
|
|
[Steve Henson]
|
|
|
|
*) Use a less unusual form of the Miller-Rabin primality test (it used
|
|
a binary algorithm for exponentiation integrated into the Miller-Rabin
|
|
loop, our standard modexp algorithms are faster).
|
|
[Bodo Moeller]
|
|
|
|
*) Support for the EBCDIC character set completed.
|
|
[Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
|
|
|
|
*) Source code cleanups: use const where appropriate, eliminate casts,
|
|
use void * instead of char * in lhash.
|
|
[Ulf Möller]
|
|
|
|
*) Bugfix: ssl3_send_server_key_exchange was not restartable
|
|
(the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
|
|
this the server could overwrite ephemeral keys that the client
|
|
has already seen).
|
|
[Bodo Moeller]
|
|
|
|
*) Turn DSA_is_prime into a macro that calls BN_is_prime,
|
|
using 50 iterations of the Rabin-Miller test.
|
|
|
|
DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
|
|
iterations of the Rabin-Miller test as required by the appendix
|
|
to FIPS PUB 186[-1]) instead of DSA_is_prime.
|
|
As BN_is_prime_fasttest includes trial division, DSA parameter
|
|
generation becomes much faster.
|
|
|
|
This implies a change for the callback functions in DSA_is_prime
|
|
and DSA_generate_parameters: The callback function is called once
|
|
for each positive witness in the Rabin-Miller test, not just
|
|
occasionally in the inner loop; and the parameters to the
|
|
callback function now provide an iteration count for the outer
|
|
loop rather than for the current invocation of the inner loop.
|
|
DSA_generate_parameters additionally can call the callback
|
|
function with an 'iteration count' of -1, meaning that a
|
|
candidate has passed the trial division test (when q is generated
|
|
from an application-provided seed, trial division is skipped).
|
|
[Bodo Moeller]
|
|
|
|
*) New function BN_is_prime_fasttest that optionally does trial
|
|
division before starting the Rabin-Miller test and has
|
|
an additional BN_CTX * argument (whereas BN_is_prime always
|
|
has to allocate at least one BN_CTX).
|
|
'callback(1, -1, cb_arg)' is called when a number has passed the
|
|
trial division stage.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix for bug in CRL encoding. The validity dates weren't being handled
|
|
as ASN1_TIME.
|
|
[Steve Henson]
|
|
|
|
*) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
|
|
[Steve Henson]
|
|
|
|
*) New function BN_pseudo_rand().
|
|
[Ulf Möller]
|
|
|
|
*) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
|
|
bignum version of BN_from_montgomery() with the working code from
|
|
SSLeay 0.9.0 (the word based version is faster anyway), and clean up
|
|
the comments.
|
|
[Ulf Möller]
|
|
|
|
*) Avoid a race condition in s2_clnt.c (function get_server_hello) that
|
|
made it impossible to use the same SSL_SESSION data structure in
|
|
SSL2 clients in multiple threads.
|
|
[Bodo Moeller]
|
|
|
|
*) The return value of RAND_load_file() no longer counts bytes obtained
|
|
by stat(). RAND_load_file(..., -1) is new and uses the complete file
|
|
to seed the PRNG (previously an explicit byte count was required).
|
|
[Ulf Möller, Bodo Möller]
|
|
|
|
*) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
|
|
used (char *) instead of (void *) and had casts all over the place.
|
|
[Steve Henson]
|
|
|
|
*) Make BN_generate_prime() return NULL on error if ret!=NULL.
|
|
[Ulf Möller]
|
|
|
|
*) Retain source code compatibility for BN_prime_checks macro:
|
|
BN_is_prime(..., BN_prime_checks, ...) now uses
|
|
BN_prime_checks_for_size to determine the appropriate number of
|
|
Rabin-Miller iterations.
|
|
[Ulf Möller]
|
|
|
|
*) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
|
|
DH_CHECK_P_NOT_SAFE_PRIME.
|
|
(Check if this is true? OpenPGP calls them "strong".)
|
|
[Ulf Möller]
|
|
|
|
*) Merge the functionality of "dh" and "gendh" programs into a new program
|
|
"dhparam". The old programs are retained for now but will handle DH keys
|
|
(instead of parameters) in future.
|
|
[Steve Henson]
|
|
|
|
*) Make the ciphers, s_server and s_client programs check the return values
|
|
when a new cipher list is set.
|
|
[Steve Henson]
|
|
|
|
*) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
|
|
ciphers. Before when the 56bit ciphers were enabled the sorting was
|
|
wrong.
|
|
|
|
The syntax for the cipher sorting has been extended to support sorting by
|
|
cipher-strength (using the strength_bits hard coded in the tables).
|
|
The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
|
|
|
|
Fix a bug in the cipher-command parser: when supplying a cipher command
|
|
string with an "undefined" symbol (neither command nor alphanumeric
|
|
[A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
|
|
an error is flagged.
|
|
|
|
Due to the strength-sorting extension, the code of the
|
|
ssl_create_cipher_list() function was completely rearranged. I hope that
|
|
the readability was also increased :-)
|
|
[Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
|
|
|
|
*) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
|
|
for the first serial number and places 2 in the serial number file. This
|
|
avoids problems when the root CA is created with serial number zero and
|
|
the first user certificate has the same issuer name and serial number
|
|
as the root CA.
|
|
[Steve Henson]
|
|
|
|
*) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
|
|
the new code. Add documentation for this stuff.
|
|
[Steve Henson]
|
|
|
|
*) Changes to X509_ATTRIBUTE utilities. These have been renamed from
|
|
X509_*() to X509at_*() on the grounds that they don't handle X509
|
|
structures and behave in an analogous way to the X509v3 functions:
|
|
they shouldn't be called directly but wrapper functions should be used
|
|
instead.
|
|
|
|
So we also now have some wrapper functions that call the X509at functions
|
|
when passed certificate requests. (TO DO: similar things can be done with
|
|
PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
|
|
things. Some of these need some d2i or i2d and print functionality
|
|
because they handle more complex structures.)
|
|
[Steve Henson]
|
|
|
|
*) Add missing #ifndefs that caused missing symbols when building libssl
|
|
as a shared library without RSA. Use #ifndef NO_SSL2 instead of
|
|
NO_RSA in ssl/s2*.c.
|
|
[Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
|
|
|
|
*) Precautions against using the PRNG uninitialized: RAND_bytes() now
|
|
has a return value which indicates the quality of the random data
|
|
(1 = ok, 0 = not seeded). Also an error is recorded on the thread's
|
|
error queue. New function RAND_pseudo_bytes() generates output that is
|
|
guaranteed to be unique but not unpredictable. RAND_add is like
|
|
RAND_seed, but takes an extra argument for an entropy estimate
|
|
(RAND_seed always assumes full entropy).
|
|
[Ulf Möller]
|
|
|
|
*) Do more iterations of Rabin-Miller probable prime test (specifically,
|
|
3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
|
|
instead of only 2 for all lengths; see BN_prime_checks_for_size definition
|
|
in crypto/bn/bn_prime.c for the complete table). This guarantees a
|
|
false-positive rate of at most 2^-80 for random input.
|
|
[Bodo Moeller]
|
|
|
|
*) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
|
|
[Bodo Moeller]
|
|
|
|
*) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
|
|
in the 0.9.5 release), this returns the chain
|
|
from an X509_CTX structure with a dup of the stack and all
|
|
the X509 reference counts upped: so the stack will exist
|
|
after X509_CTX_cleanup() has been called. Modify pkcs12.c
|
|
to use this.
|
|
|
|
Also make SSL_SESSION_print() print out the verify return
|
|
code.
|
|
[Steve Henson]
|
|
|
|
*) Add manpage for the pkcs12 command. Also change the default
|
|
behaviour so MAC iteration counts are used unless the new
|
|
-nomaciter option is used. This improves file security and
|
|
only older versions of MSIE (4.0 for example) need it.
|
|
[Steve Henson]
|
|
|
|
*) Honor the no-xxx Configure options when creating .DEF files.
|
|
[Ulf Möller]
|
|
|
|
*) Add PKCS#10 attributes to field table: challengePassword,
|
|
unstructuredName and unstructuredAddress. These are taken from
|
|
draft PKCS#9 v2.0 but are compatible with v1.2 provided no
|
|
international characters are used.
|
|
|
|
More changes to X509_ATTRIBUTE code: allow the setting of types
|
|
based on strings. Remove the 'loc' parameter when adding
|
|
attributes because these will be a SET OF encoding which is sorted
|
|
in ASN1 order.
|
|
[Steve Henson]
|
|
|
|
*) Initial changes to the 'req' utility to allow request generation
|
|
automation. This will allow an application to just generate a template
|
|
file containing all the field values and have req construct the
|
|
request.
|
|
|
|
Initial support for X509_ATTRIBUTE handling. Stacks of these are
|
|
used all over the place including certificate requests and PKCS#7
|
|
structures. They are currently handled manually where necessary with
|
|
some primitive wrappers for PKCS#7. The new functions behave in a
|
|
manner analogous to the X509 extension functions: they allow
|
|
attributes to be looked up by NID and added.
|
|
|
|
Later something similar to the X509V3 code would be desirable to
|
|
automatically handle the encoding, decoding and printing of the
|
|
more complex types. The string types like challengePassword can
|
|
be handled by the string table functions.
|
|
|
|
Also modified the multi byte string table handling. Now there is
|
|
a 'global mask' which masks out certain types. The table itself
|
|
can use the flag STABLE_NO_MASK to ignore the mask setting: this
|
|
is useful when for example there is only one permissible type
|
|
(as in countryName) and using the mask might result in no valid
|
|
types at all.
|
|
[Steve Henson]
|
|
|
|
*) Clean up 'Finished' handling, and add functions SSL_get_finished and
|
|
SSL_get_peer_finished to allow applications to obtain the latest
|
|
Finished messages sent to the peer or expected from the peer,
|
|
respectively. (SSL_get_peer_finished is usually the Finished message
|
|
actually received from the peer, otherwise the protocol will be aborted.)
|
|
|
|
As the Finished message are message digests of the complete handshake
|
|
(with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
|
|
be used for external authentication procedures when the authentication
|
|
provided by SSL/TLS is not desired or is not enough.
|
|
[Bodo Moeller]
|
|
|
|
*) Enhanced support for Alpha Linux is added. Now ./config checks if
|
|
the host supports BWX extension and if Compaq C is present on the
|
|
$PATH. Just exploiting of the BWX extension results in 20-30%
|
|
performance kick for some algorithms, e.g. DES and RC4 to mention
|
|
a couple. Compaq C in turn generates ~20% faster code for MD5 and
|
|
SHA1.
|
|
[Andy Polyakov]
|
|
|
|
*) Add support for MS "fast SGC". This is arguably a violation of the
|
|
SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
|
|
weak crypto and after checking the certificate is SGC a second one
|
|
with strong crypto. MS SGC stops the first handshake after receiving
|
|
the server certificate message and sends a second client hello. Since
|
|
a server will typically do all the time consuming operations before
|
|
expecting any further messages from the client (server key exchange
|
|
is the most expensive) there is little difference between the two.
|
|
|
|
To get OpenSSL to support MS SGC we have to permit a second client
|
|
hello message after we have sent server done. In addition we have to
|
|
reset the MAC if we do get this second client hello.
|
|
[Steve Henson]
|
|
|
|
*) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
|
|
if a DER encoded private key is RSA or DSA traditional format. Changed
|
|
d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
|
|
format DER encoded private key. Newer code should use PKCS#8 format which
|
|
has the key type encoded in the ASN1 structure. Added DER private key
|
|
support to pkcs8 application.
|
|
[Steve Henson]
|
|
|
|
*) SSL 3/TLS 1 servers now don't request certificates when an anonymous
|
|
ciphersuites has been selected (as required by the SSL 3/TLS 1
|
|
specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
|
|
is set, we interpret this as a request to violate the specification
|
|
(the worst that can happen is a handshake failure, and 'correct'
|
|
behaviour would result in a handshake failure anyway).
|
|
[Bodo Moeller]
|
|
|
|
*) In SSL_CTX_add_session, take into account that there might be multiple
|
|
SSL_SESSION structures with the same session ID (e.g. when two threads
|
|
concurrently obtain them from an external cache).
|
|
The internal cache can handle only one SSL_SESSION with a given ID,
|
|
so if there's a conflict, we now throw out the old one to achieve
|
|
consistency.
|
|
[Bodo Moeller]
|
|
|
|
*) Add OIDs for idea and blowfish in CBC mode. This will allow both
|
|
to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
|
|
some routines that use cipher OIDs: some ciphers do not have OIDs
|
|
defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
|
|
example.
|
|
[Steve Henson]
|
|
|
|
*) Simplify the trust setting structure and code. Now we just have
|
|
two sequences of OIDs for trusted and rejected settings. These will
|
|
typically have values the same as the extended key usage extension
|
|
and any application specific purposes.
|
|
|
|
The trust checking code now has a default behaviour: it will just
|
|
check for an object with the same NID as the passed id. Functions can
|
|
be provided to override either the default behaviour or the behaviour
|
|
for a given id. SSL client, server and email already have functions
|
|
in place for compatibility: they check the NID and also return "trusted"
|
|
if the certificate is self signed.
|
|
[Steve Henson]
|
|
|
|
*) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
|
|
traditional format into an EVP_PKEY structure.
|
|
[Steve Henson]
|
|
|
|
*) Add a password callback function PEM_cb() which either prompts for
|
|
a password if usr_data is NULL or otherwise assumes it is a null
|
|
terminated password. Allow passwords to be passed on command line
|
|
environment or config files in a few more utilities.
|
|
[Steve Henson]
|
|
|
|
*) Add a bunch of DER and PEM functions to handle PKCS#8 format private
|
|
keys. Add some short names for PKCS#8 PBE algorithms and allow them
|
|
to be specified on the command line for the pkcs8 and pkcs12 utilities.
|
|
Update documentation.
|
|
[Steve Henson]
|
|
|
|
*) Support for ASN1 "NULL" type. This could be handled before by using
|
|
ASN1_TYPE but there wasn't any function that would try to read a NULL
|
|
and produce an error if it couldn't. For compatibility we also have
|
|
ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
|
|
don't allocate anything because they don't need to.
|
|
[Steve Henson]
|
|
|
|
*) Initial support for MacOS is now provided. Examine INSTALL.MacOS
|
|
for details.
|
|
[Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
|
|
|
|
*) Rebuild of the memory allocation routines used by OpenSSL code and
|
|
possibly others as well. The purpose is to make an interface that
|
|
provide hooks so anyone can build a separate set of allocation and
|
|
deallocation routines to be used by OpenSSL, for example memory
|
|
pool implementations, or something else, which was previously hard
|
|
since Malloc(), Realloc() and Free() were defined as macros having
|
|
the values malloc, realloc and free, respectively (except for Win32
|
|
compilations). The same is provided for memory debugging code.
|
|
OpenSSL already comes with functionality to find memory leaks, but
|
|
this gives people a chance to debug other memory problems.
|
|
|
|
With these changes, a new set of functions and macros have appeared:
|
|
|
|
CRYPTO_set_mem_debug_functions() [F]
|
|
CRYPTO_get_mem_debug_functions() [F]
|
|
CRYPTO_dbg_set_options() [F]
|
|
CRYPTO_dbg_get_options() [F]
|
|
CRYPTO_malloc_debug_init() [M]
|
|
|
|
The memory debug functions are NULL by default, unless the library
|
|
is compiled with CRYPTO_MDEBUG or friends is defined. If someone
|
|
wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
|
|
gives the standard debugging functions that come with OpenSSL) or
|
|
CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
|
|
provided by the library user) must be used. When the standard
|
|
debugging functions are used, CRYPTO_dbg_set_options can be used to
|
|
request additional information:
|
|
CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
|
|
the CRYPTO_MDEBUG_xxx macro when compiling the library.
|
|
|
|
Also, things like CRYPTO_set_mem_functions will always give the
|
|
expected result (the new set of functions is used for allocation
|
|
and deallocation) at all times, regardless of platform and compiler
|
|
options.
|
|
|
|
To finish it up, some functions that were never use in any other
|
|
way than through macros have a new API and new semantic:
|
|
|
|
CRYPTO_dbg_malloc()
|
|
CRYPTO_dbg_realloc()
|
|
CRYPTO_dbg_free()
|
|
|
|
All macros of value have retained their old syntax.

|
|
|
|
*) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
|
|
ordering of SMIMECapabilities wasn't in "strength order" and there
|
|
was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
|
|
algorithm.
|
|
[Steve Henson]
|
|
|
|
*) Some ASN1 types with illegal zero length encoding (INTEGER,
|
|
ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
|
|
[Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
|
|
|
|
*) Merge in my S/MIME library for OpenSSL. This provides a simple
|
|
S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
|
|
functionality to handle multipart/signed properly) and a utility
|
|
called 'smime' to call all this stuff. This is based on code I
|
|
originally wrote for Celo who have kindly allowed it to be
|
|
included in OpenSSL.
|
|
[Steve Henson]
|
|
|
|
*) Add variants des_set_key_checked and des_set_key_unchecked of
|
|
des_set_key (aka des_key_sched). Global variable des_check_key
|
|
decides which of these is called by des_set_key; this way
|
|
des_check_key behaves as it always did, but applications and
|
|
the library itself, which was buggy for des_check_key == 1,
|
|
have a cleaner way to pick the version they need.
|
|
[Bodo Moeller]
|
|
|
|
*) New function PKCS12_newpass() which changes the password of a
|
|
PKCS12 structure.
|
|
[Steve Henson]
|
|
|
|
*) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
|
|
dynamic mix. In both cases the ids can be used as an index into the
|
|
table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
|
|
functions so they accept a list of the field values and the
|
|
application doesn't need to directly manipulate the X509_TRUST
|
|
structure.
|
|
[Steve Henson]
|
|
|
|
*) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
|
|
need initialising.
|
|
[Steve Henson]
|
|
|
|
*) Modify the way the V3 extension code looks up extensions. This now
|
|
works in a similar way to the object code: we have some "standard"
|
|
extensions in a static table which is searched with OBJ_bsearch()
|
|
and the application can add dynamic ones if needed. The file
|
|
crypto/x509v3/ext_dat.h now has the info: this file needs to be
|
|
updated whenever a new extension is added to the core code and kept
|
|
in ext_nid order. There is a simple program 'tabtest.c' which checks
|
|
this. New extensions are not added too often so this file can readily
|
|
be maintained manually.
|
|
|
|
There are two big advantages in doing things this way. The extensions
|
|
can be looked up immediately and no longer need to be "added" using
|
|
X509V3_add_standard_extensions(): this function now does nothing.
|
|
[Side note: I get *lots* of email saying the extension code doesn't
|
|
work because people forget to call this function]
|
|
Also no dynamic allocation is done unless new extensions are added:
|
|
so if we don't add custom extensions there is no need to call
|
|
X509V3_EXT_cleanup().
|
|
[Steve Henson]
|
|
|
|
*) Modify enc utility's salting as follows: make salting the default. Add a
|
|
magic header, so unsalted files fail gracefully instead of just decrypting
|
|
to garbage. This is because not salting is a big security hole, so people
|
|
should be discouraged from doing it.
|
|
[Ben Laurie]
|
|
|
|
*) Fixes and enhancements to the 'x509' utility. It allowed a message
|
|
digest to be passed on the command line but it only used this
|
|
parameter when signing a certificate. Modified so all relevant
|
|
operations are affected by the digest parameter including the
|
|
-fingerprint and -x509toreq options. Also -x509toreq choked if a
|
|
DSA key was used because it didn't fix the digest.
|
|
[Steve Henson]
|
|
|
|
*) Initial certificate chain verify code. Currently tests the untrusted
|
|
certificates for consistency with the verify purpose (which is set
|
|
when the X509_STORE_CTX structure is set up) and checks the pathlength.
|
|
|
|
There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
|
|
this is because it will reject chains with invalid extensions whereas
|
|
every previous version of OpenSSL and SSLeay made no checks at all.
|
|
|
|
Trust code: checks the root CA for the relevant trust settings. Trust
|
|
settings have an initial value consistent with the verify purpose: e.g.
|
|
if the verify purpose is for SSL client use it expects the CA to be
|
|
trusted for SSL client use. However the default value can be changed to
|
|
permit custom trust settings: one example of this would be to only trust
|
|
certificates from a specific "secure" set of CAs.
|
|
|
|
Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
|
|
which should be used for version portability: especially since the
|
|
verify structure is likely to change more often now.
|
|
|
|
SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
|
|
to set them. If not set then assume SSL clients will verify SSL servers
|
|
and vice versa.
|
|
|
|
Two new options to the verify program: -untrusted allows a set of
|
|
untrusted certificates to be passed in and -purpose which sets the
|
|
intended purpose of the certificate. If a purpose is set then the
|
|
new chain verify code is used to check extension consistency.
|
|
[Steve Henson]
|
|
|
|
*) Support for the authority information access extension.
|
|
[Steve Henson]
|
|
|
|
*) Modify RSA and DSA PEM read routines to transparently handle
|
|
PKCS#8 format private keys. New *_PUBKEY_* functions that handle
|
|
public keys in a format compatible with certificate
|
|
SubjectPublicKeyInfo structures. Unfortunately there were already
|
|
functions called *_PublicKey_* which used various odd formats so
|
|
these are retained for compatibility: however the DSA variants were
|
|
never in a public release so they have been deleted. Changed dsa/rsa
|
|
utilities to handle the new format: note no releases ever handled public
|
|
keys so we should be OK.
|
|
|
|
The primary motivation for this change is to avoid the same fiasco
|
|
that dogs private keys: there are several incompatible private key
|
|
formats some of which are standard and some OpenSSL specific and
|
|
require various evil hacks to allow partial transparent handling and
|
|
even then it doesn't work with DER formats. Given the option anything
|
|
other than PKCS#8 should be dumped: but the other formats have to
|
|
stay in the name of compatibility.
|
|
|
|
With public keys and the benefit of hindsight one standard format
|
|
is used which works with EVP_PKEY, RSA or DSA structures: though
|
|
it clearly returns an error if you try to read the wrong kind of key.
|
|
|
|
Added a -pubkey option to the 'x509' utility to output the public key.
|
|
Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
|
|
(renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
|
|
EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
|
|
that do the same as the EVP_PKEY_assign_*() except they up the
|
|
reference count of the added key (they don't "swallow" the
|
|
supplied key).
|
|
[Steve Henson]
|
|
|
|
*) Fixes to crypto/x509/by_file.c the code to read in certificates and
|
|
CRLs would fail if the file contained no certificates or no CRLs:
|
|
added a new function to read in both types and return the number
|
|
read: this means that if none are read it will be an error. The
|
|
DER versions of the certificate and CRL reader would always fail
|
|
because it isn't possible to mix certificates and CRLs in DER format
|
|
without choking one or the other routine. Changed this to just read
|
|
a certificate: this is the best we can do. Also modified the code
|
|
in apps/verify.c to take notice of return codes: it was previously
|
|
attempting to read in certificates from NULL pointers and ignoring
|
|
any errors: this is one reason why the cert and CRL reader seemed
|
|
to work. It doesn't check return codes from the default certificate
|
|
routines: these may well fail if the certificates aren't installed.
|
|
[Steve Henson]
|
|
|
|
*) Code to support otherName option in GeneralName.
|
|
[Steve Henson]
|
|
|
|
*) First update to verify code. Change the verify utility
|
|
so it warns if it is passed a self signed certificate:
|
|
for consistency with the normal behaviour. X509_verify
|
|
has been modified to it will now verify a self signed
|
|
certificate if *exactly* the same certificate appears
|
|
in the store: it was previously impossible to trust a
|
|
single self signed certificate. This means that:
|
|
openssl verify ss.pem
|
|
now gives a warning about a self signed certificate but
|
|
openssl verify -CAfile ss.pem ss.pem
|
|
is OK.
|
|
[Steve Henson]
|
|
|
|
*) For servers, store verify_result in SSL_SESSION data structure
|
|
(and add it to external session representation).
|
|
This is needed when client certificate verifications fails,
|
|
but an application-provided verification callback (set by
|
|
SSL_CTX_set_cert_verify_callback) allows accepting the session
|
|
anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
|
|
but returns 1): When the session is reused, we have to set
|
|
ssl->verify_result to the appropriate error code to avoid
|
|
security holes.
|
|
[Bodo Moeller, problem pointed out by Lutz Jaenicke]
|
|
|
|
*) Fix a bug in the new PKCS#7 code: it didn't consider the
|
|
case in PKCS7_dataInit() where the signed PKCS7 structure
|
|
didn't contain any existing data because it was being created.
|
|
[Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
|
|
|
|
*) Add a salt to the key derivation routines in enc.c. This
|
|
forms the first 8 bytes of the encrypted file. Also add a
|
|
-S option to allow a salt to be input on the command line.
|
|
[Steve Henson]
|
|
|
|
*) New function X509_cmp(). Oddly enough there wasn't a function
|
|
to compare two certificates. We do this by working out the SHA1
|
|
hash and comparing that. X509_cmp() will be needed by the trust
|
|
code.
|
|
[Steve Henson]
|
|
|
|
*) SSL_get1_session() is like SSL_get_session(), but increments
|
|
the reference count in the SSL_SESSION returned.
|
|
[Geoff Thorpe <geoff@eu.c2.net>]
|
|
|
|
*) Fix for 'req': it was adding a null to request attributes.
|
|
Also change the X509_LOOKUP and X509_INFO code to handle
|
|
certificate auxiliary information.
|
|
[Steve Henson]
|
|
|
|
*) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
|
|
the 'enc' command.
|
|
[Steve Henson]
|
|
|
|
*) Add the possibility to add extra information to the memory leak
|
|
detecting output, to form tracebacks, showing from where each
|
|
allocation was originated: CRYPTO_push_info("constant string") adds
|
|
the string plus current file name and line number to a per-thread
|
|
stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
|
|
is like calling CYRPTO_pop_info() until the stack is empty.
|
|
Also updated memory leak detection code to be multi-thread-safe.
|
|
[Richard Levitte]
|
|
|
|
*) Add options -text and -noout to pkcs7 utility and delete the
|
|
encryption options which never did anything. Update docs.
|
|
[Steve Henson]
|
|
|
|
*) Add options to some of the utilities to allow the pass phrase
|
|
to be included on either the command line (not recommended on
|
|
OSes like Unix) or read from the environment. Update the
|
|
manpages and fix a few bugs.
|
|
[Steve Henson]
|
|
|
|
*) Add a few manpages for some of the openssl commands.
|
|
[Steve Henson]
|
|
|
|
*) Fix the -revoke option in ca. It was freeing up memory twice,
|
|
leaking and not finding already revoked certificates.
|
|
[Steve Henson]
|
|
|
|
*) Extensive changes to support certificate auxiliary information.
|
|
This involves the use of X509_CERT_AUX structure and X509_AUX
|
|
functions. An X509_AUX function such as PEM_read_X509_AUX()
|
|
can still read in a certificate file in the usual way but it
|
|
will also read in any additional "auxiliary information". By
|
|
doing things this way a fair degree of compatibility can be
|
|
retained: existing certificates can have this information added
|
|
using the new 'x509' options.
|
|
|
|
Current auxiliary information includes an "alias" and some trust
|
|
settings. The trust settings will ultimately be used in enhanced
|
|
certificate chain verification routines: currently a certificate
|
|
can only be trusted if it is self signed and then it is trusted
|
|
for all purposes.
|
|
[Steve Henson]
|
|
|
|
*) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
|
|
The problem was that one of the replacement routines had not been working
|
|
since SSLeay releases. For now the offending routine has been replaced
|
|
with non-optimised assembler. Even so, this now gives around 95%
|
|
performance improvement for 1024 bit RSA signs.
|
|
[Mark Cox]
|
|
|
|
*) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
|
|
handling. Most clients have the effective key size in bits equal to
|
|
the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
|
|
A few however don't do this and instead use the size of the decrypted key
|
|
to determine the RC2 key length and the AlgorithmIdentifier to determine
|
|
the effective key length. In this case the effective key length can still
|
|
be 40 bits but the key length can be 168 bits for example. This is fixed
|
|
by manually forcing an RC2 key into the EVP_PKEY structure because the
|
|
EVP code can't currently handle unusual RC2 key sizes: it always assumes
|
|
the key length and effective key length are equal.
|
|
[Steve Henson]
|
|
|
|
*) Add a bunch of functions that should simplify the creation of
|
|
X509_NAME structures. Now you should be able to do:
|
|
X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
|
|
and have it automatically work out the correct field type and fill in
|
|
the structures. The more adventurous can try:
|
|
X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
|
|
and it will (hopefully) work out the correct multibyte encoding.
|
|
[Steve Henson]
|
|
|
|
*) Change the 'req' utility to use the new field handling and multibyte
|
|
copy routines. Before the DN field creation was handled in an ad hoc
|
|
way in req, ca, and x509 which was rather broken and didn't support
|
|
BMPStrings or UTF8Strings. Since some software doesn't implement
|
|
BMPStrings or UTF8Strings yet, they can be enabled using the config file
|
|
using the dirstring_type option. See the new comment in the default
|
|
openssl.cnf for more info.
|
|
[Steve Henson]
|
|
|
|
*) Make crypto/rand/md_rand.c more robust:
|
|
- Assure unique random numbers after fork().
|
|
- Make sure that concurrent threads access the global counter and
|
|
md serializably so that we never lose entropy in them
|
|
or use exactly the same state in multiple threads.
|
|
Access to the large state is not always serializable because
|
|
the additional locking could be a performance killer, and
|
|
md should be large enough anyway.
|
|
[Bodo Moeller]
|
|
|
|
*) New file apps/app_rand.c with commonly needed functionality
|
|
for handling the random seed file.
|
|
|
|
Use the random seed file in some applications that previously did not:
|
|
ca,
|
|
dsaparam -genkey (which also ignored its '-rand' option),
|
|
s_client,
|
|
s_server,
|
|
x509 (when signing).
|
|
Except on systems with /dev/urandom, it is crucial to have a random
|
|
seed file at least for key creation, DSA signing, and for DH exchanges;
|
|
for RSA signatures we could do without one.
|
|
|
|
gendh and gendsa (unlike genrsa) used to read only the first byte
|
|
of each file listed in the '-rand' option. The function as previously
|
|
found in genrsa is now in app_rand.c and is used by all programs
|
|
that support '-rand'.
|
|
[Bodo Moeller]
|
|
|
|
*) In RAND_write_file, use mode 0600 for creating files;
|
|
don't just chmod when it may be too late.
|
|
[Bodo Moeller]
|
|
|
|
*) Report an error from X509_STORE_load_locations
|
|
when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
|
|
[Bill Perry]
|
|
|
|
*) New function ASN1_mbstring_copy() this copies a string in either
|
|
ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
|
|
into an ASN1_STRING type. A mask of permissible types is passed
|
|
and it chooses the "minimal" type to use or an error if not type
|
|
is suitable.
|
|
[Steve Henson]
|
|
|
|
*) Add function equivalents to the various macros in asn1.h. The old
|
|
macros are retained with an M_ prefix. Code inside the library can
|
|
use the M_ macros. External code (including the openssl utility)
|
|
should *NOT* in order to be "shared library friendly".
|
|
[Steve Henson]
|
|
|
|
*) Add various functions that can check a certificate's extensions
|
|
to see if it usable for various purposes such as SSL client,
|
|
server or S/MIME and CAs of these types. This is currently
|
|
VERY EXPERIMENTAL but will ultimately be used for certificate chain
|
|
verification. Also added a -purpose flag to x509 utility to
|
|
print out all the purposes.
|
|
[Steve Henson]
|
|
|
|
*) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
|
|
functions.
|
|
[Steve Henson]
|
|
|
|
*) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
|
|
for, obtain and decode and extension and obtain its critical flag.
|
|
This allows all the necessary extension code to be handled in a
|
|
single function call.
|
|
[Steve Henson]
|
|
|
|
*) RC4 tune-up featuring 30-40% performance improvement on most RISC
|
|
platforms. See crypto/rc4/rc4_enc.c for further details.
|
|
[Andy Polyakov]
|
|
|
|
*) New -noout option to asn1parse. This causes no output to be produced
|
|
its main use is when combined with -strparse and -out to extract data
|
|
from a file (which may not be in ASN.1 format).
|
|
[Steve Henson]
|
|
|
|
*) Fix for pkcs12 program. It was hashing an invalid certificate pointer
|
|
when producing the local key id.
|
|
[Richard Levitte <levitte@stacken.kth.se>]
|
|
|
|
*) New option -dhparam in s_server. This allows a DH parameter file to be
|
|
stated explicitly. If it is not stated then it tries the first server
|
|
certificate file. The previous behaviour hard coded the filename
|
|
"server.pem".
|
|
[Steve Henson]
|
|
|
|
*) Add -pubin and -pubout options to the rsa and dsa commands. These allow
|
|
a public key to be input or output. For example:
|
|
openssl rsa -in key.pem -pubout -out pubkey.pem
|
|
Also added necessary DSA public key functions to handle this.
|
|
[Steve Henson]
|
|
|
|
*) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
|
|
in the message. This was handled by allowing
|
|
X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
|
|
[Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
|
|
|
|
*) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
|
|
to the end of the strings whereas this didn't. This would cause problems
|
|
if strings read with d2i_ASN1_bytes() were later modified.
|
|
[Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
|
|
|
|
*) Fix for base64 decode bug. When a base64 bio reads only one line of
|
|
data and it contains EOF it will end up returning an error. This is
|
|
caused by input 46 bytes long. The cause is due to the way base64
|
|
BIOs find the start of base64 encoded data. They do this by trying a
|
|
trial decode on each line until they find one that works. When they
|
|
do a flag is set and it starts again knowing it can pass all the
|
|
data directly through the decoder. Unfortunately it doesn't reset
|
|
the context it uses. This means that if EOF is reached an attempt
|
|
is made to pass two EOFs through the context and this causes the
|
|
resulting error. This can also cause other problems as well. As is
|
|
usual with these problems it takes *ages* to find and the fix is
|
|
trivial: move one line.
|
|
[Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
|
|
|
|
*) Ugly workaround to get s_client and s_server working under Windows. The
|
|
old code wouldn't work because it needed to select() on sockets and the
|
|
tty (for keypresses and to see if data could be written). Win32 only
|
|
supports select() on sockets so we select() with a 1s timeout on the
|
|
sockets and then see if any characters are waiting to be read, if none
|
|
are present then we retry, we also assume we can always write data to
|
|
the tty. This isn't nice because the code then blocks until we've
|
|
received a complete line of data and it is effectively polling the
|
|
keyboard at 1s intervals: however it's quite a bit better than not
|
|
working at all :-) A dedicated Windows application might handle this
|
|
with an event loop for example.

*) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
|
|
and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
|
|
will be called when RSA_sign() and RSA_verify() are used. This is useful
|
|
if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
|
|
For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
|
|
should *not* be used: RSA_sign() and RSA_verify() must be used instead.
|
|
This necessitated the support of an extra signature type NID_md5_sha1
|
|
for SSL signatures and modifications to the SSL library to use it instead
|
|
of calling RSA_public_decrypt() and RSA_private_encrypt().
|
|
[Steve Henson]
|
|
|
|
*) Add new -verify -CAfile and -CApath options to the crl program, these
|
|
will lookup a CRL issuers certificate and verify the signature in a
|
|
similar way to the verify program. Tidy up the crl program so it
|
|
no longer accesses structures directly. Make the ASN1 CRL parsing a bit
|
|
less strict. It will now permit CRL extensions even if it is not
|
|
a V2 CRL: this will allow it to tolerate some broken CRLs.
|
|
[Steve Henson]
|
|
|
|
*) Initialize all non-automatic variables each time one of the openssl
|
|
sub-programs is started (this is necessary as they may be started
|
|
multiple times from the "OpenSSL>" prompt).
|
|
[Lennart Bang, Bodo Moeller]
|
|
|
|
*) Preliminary compilation option RSA_NULL which disables RSA crypto without
|
|
removing all other RSA functionality (this is what NO_RSA does). This
|
|
is so (for example) those in the US can disable those operations covered
|
|
by the RSA patent while allowing storage and parsing of RSA keys and RSA
|
|
key generation.
|
|
[Steve Henson]
|
|
|
|
*) Non-copying interface to BIO pairs.
|
|
(still largely untested)
|
|
[Bodo Moeller]
|
|
|
|
*) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
|
|
ASCII string. This was handled independently in various places before.
|
|
[Steve Henson]
|
|
|
|
*) New functions UTF8_getc() and UTF8_putc() that parse and generate
|
|
UTF8 strings a character at a time.
|
|
[Steve Henson]
|
|
|
|
*) Use client_version from client hello to select the protocol
|
|
(s23_srvr.c) and for RSA client key exchange verification
|
|
(s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
|
|
[Bodo Moeller]
|
|
|
|
*) Add various utility functions to handle SPKACs, these were previously
|
|
handled by poking round in the structure internals. Added new function
|
|
NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
|
|
print, verify and generate SPKACs. Based on an original idea from
|
|
Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
|
|
[Steve Henson]
|
|
|
|
*) RIPEMD160 is operational on all platforms and is back in 'make test'.
|
|
[Andy Polyakov]
|
|
|
|
*) Allow the config file extension section to be overwritten on the
|
|
command line. Based on an original idea from Massimiliano Pala
|
|
<madwolf@comune.modena.it>. The new option is called -extensions
|
|
and can be applied to ca, req and x509. Also -reqexts to override
|
|
the request extensions in req and -crlexts to override the crl extensions
|
|
in ca.
|
|
[Steve Henson]
|
|
|
|
*) Add new feature to the SPKAC handling in ca. Now you can include
|
|
the same field multiple times by preceding it by "XXXX." for example:
|
|
1.OU="Unit name 1"
|
|
2.OU="Unit name 2"
|
|
this is the same syntax as used in the req config file.
|
|
[Steve Henson]
|
|
|
|
*) Allow certificate extensions to be added to certificate requests. These
|
|
are specified in a 'req_extensions' option of the req section of the
|
|
config file. They can be printed out with the -text option to req but
|
|
are otherwise ignored at present.
|
|
[Steve Henson]
|
|
|
|
*) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
|
|
data read consists of only the final block it would not decrypted because
|
|
EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
|
|
A misplaced 'break' also meant the decrypted final block might not be
|
|
copied until the next read.
|
|
[Steve Henson]
|
|
|
|
*) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
|
|
a few extra parameters to the DH structure: these will be useful if
|
|
for example we want the value of 'q' or implement X9.42 DH.
|
|
[Steve Henson]
|
|
|
|
*) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
|
|
provides hooks that allow the default DSA functions or functions on a
|
|
"per key" basis to be replaced. This allows hardware acceleration and
|
|
hardware key storage to be handled without major modification to the
|
|
library. Also added low level modexp hooks and CRYPTO_EX structure and
|
|
associated functions.
|
|
[Steve Henson]
|
|
|
|
*) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
|
|
as "read only": it can't be written to and the buffer it points to will
|
|
not be freed. Reading from a read only BIO is much more efficient than
|
|
a normal memory BIO. This was added because there are several times when
|
|
an area of memory needs to be read from a BIO. The previous method was
|
|
to create a memory BIO and write the data to it, this results in two
|
|
copies of the data and an O(n^2) reading algorithm. There is a new
|
|
function BIO_new_mem_buf() which creates a read only memory BIO from
|
|
an area of memory. Also modified the PKCS#7 routines to use read only
|
|
memory BIOs.
|
|
[Steve Henson]
|
|
|
|
*) Bugfix: ssl23_get_client_hello did not work properly when called in
|
|
state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
|
|
a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
|
|
but a retry condition occurred while trying to read the rest.
|
|
[Bodo Moeller]
|
|
|
|
*) The PKCS7_ENC_CONTENT_new() function was setting the content type as
|
|
NID_pkcs7_encrypted by default: this was wrong since this should almost
|
|
always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
|
|
the encrypted data type: this is a more sensible place to put it and it
|
|
allows the PKCS#12 code to be tidied up that duplicated this
|
|
functionality.
|
|
[Steve Henson]
|
|
|
|
*) Changed obj_dat.pl script so it takes its input and output files on
|
|
the command line. This should avoid shell escape redirection problems
|
|
under Win32.
|
|
[Steve Henson]
|
|
|
|
*) Initial support for certificate extension requests, these are included
|
|
in things like Xenroll certificate requests. Included functions to allow
|
|
extensions to be obtained and added.
|
|
[Steve Henson]
|
|
|
|
*) -crlf option to s_client and s_server for sending newlines as
|
|
CRLF (as required by many protocols).
|
|
[Bodo Moeller]
|
|
|
|
Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
|
|
|
|
*) Install libRSAglue.a when OpenSSL is built with RSAref.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
|
|
[Andrija Antonijevic <TheAntony2@bigfoot.com>]
|
|
|
|
*) Fix -startdate and -enddate (which was missing) arguments to 'ca'
|
|
program.
|
|
[Steve Henson]
|
|
|
|
*) New function DSA_dup_DH, which duplicates DSA parameters/keys as
|
|
DH parameters/keys (q is lost during that conversion, but the resulting
|
|
DH parameters contain its length).
|
|
|
|
For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
|
|
much faster than DH_generate_parameters (which creates parameters
|
|
where p = 2*q + 1), and also the smaller q makes DH computations
|
|
much more efficient (160-bit exponentiation instead of 1024-bit
|
|
exponentiation); so this provides a convenient way to support DHE
|
|
ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
|
|
utter importance to use
|
|
SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
|
|
or
|
|
SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
|
|
when such DH parameters are used, because otherwise small subgroup
|
|
attacks may become possible!
|
|
[Bodo Moeller]
|
|
|
|
*) Avoid memory leak in i2d_DHparams.
|
|
[Bodo Moeller]
|
|
|
|
*) Allow the -k option to be used more than once in the enc program:
|
|
this allows the same encrypted message to be read by multiple recipients.
|
|
[Steve Henson]
|
|
|
|
*) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
|
|
an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
|
|
it will always use the numerical form of the OID, even if it has a short
|
|
or long name.
|
|
[Steve Henson]
|
|
|
|
*) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
|
|
method only got called if p,q,dmp1,dmq1,iqmp components were present,
|
|
otherwise bn_mod_exp was called. In the case of hardware keys for example
|
|
no private key components need be present and it might store extra data
|
|
in the RSA structure, which cannot be accessed from bn_mod_exp.
|
|
By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
|
|
private key operations.
|
|
[Steve Henson]
|
|
|
|
*) Added support for SPARC Linux.
|
|
[Andy Polyakov]
|
|
|
|
*) pem_password_cb function type incompatibly changed from
|
|
typedef int pem_password_cb(char *buf, int size, int rwflag);
|
|
to
|
|
....(char *buf, int size, int rwflag, void *userdata);
|
|
so that applications can pass data to their callbacks:
|
|
The PEM[_ASN1]_{read,write}... functions and macros now take an
|
|
additional void * argument, which is just handed through whenever
|
|
the password callback is called.
|
|
[Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
|
|
|
|
New function SSL_CTX_set_default_passwd_cb_userdata.
|
|
|
|
Compatibility note: As many C implementations push function arguments
|
|
onto the stack in reverse order, the new library version is likely to
|
|
interoperate with programs that have been compiled with the old
|
|
pem_password_cb definition (PEM_whatever takes some data that
|
|
happens to be on the stack as its last argument, and the callback
|
|
just ignores this garbage); but there is no guarantee whatsoever that
|
|
this will work.
|
|
|
|
*) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
|
|
(both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
|
|
problems not only on Windows, but also on some Unix platforms.
|
|
To avoid problematic command lines, these definitions are now in an
|
|
auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
|
|
for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
|
|
[Bodo Moeller]
|
|
|
|
*) MIPS III/IV assembler module is reimplemented.
|
|
[Andy Polyakov]
|
|
|
|
*) More DES library cleanups: remove references to srand/rand and
|
|
delete an unused file.
|
|
[Ulf Möller]
|
|
|
|
*) Add support for the free Netwide assembler (NASM) under Win32,
|
|
since not many people have MASM (ml) and it can be hard to obtain.
|
|
This is currently experimental but it seems to work OK and pass all
|
|
the tests. Check out INSTALL.W32 for info.
|
|
[Steve Henson]
|
|
|
|
*) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
|
|
without temporary keys kept an extra copy of the server key,
|
|
and connections with temporary keys did not free everything in case
|
|
of an error.
|
|
[Bodo Moeller]
|
|
|
|
*) New function RSA_check_key and new openssl rsa option -check
|
|
for verifying the consistency of RSA keys.
|
|
[Ulf Moeller, Bodo Moeller]
|
|
|
|
*) Various changes to make Win32 compile work:
|
|
1. Casts to avoid "loss of data" warnings in p5_crpt2.c
|
|
2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
|
|
comparison" warnings.
|
|
3. Add sk_<TYPE>_sort to DEF file generator and do make update.
|
|
[Steve Henson]
|
|
|
|
*) Add a debugging option to PKCS#5 v2 key generation function: when
|
|
you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
|
|
derived keys are printed to stderr.
|
|
[Steve Henson]
|
|
|
|
*) Copy the flags in ASN1_STRING_dup().
|
|
[Roman E. Pavlov <pre@mo.msk.ru>]
|
|
|
|
*) The x509 application mishandled signing requests containing DSA
|
|
keys when the signing key was also DSA and the parameters didn't match.
|
|
|
|
It was supposed to omit the parameters when they matched the signing key:
|
|
the verifying software was then supposed to automatically use the CA's
|
|
parameters if they were absent from the end user certificate.
|
|
|
|
Omitting parameters is no longer recommended. The test was also
|
|
the wrong way round! This was probably due to unusual behaviour in
|
|
EVP_cmp_parameters() which returns 1 if the parameters match.
|
|
This meant that parameters were omitted when they *didn't* match and
|
|
the certificate was useless. Certificates signed with 'ca' didn't have
|
|
this bug.
|
|
[Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
|
|
|
|
*) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
|
|
The interface is as follows:
|
|
Applications can use
|
|
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
|
|
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
|
|
"off" is now the default.
|
|
The library internally uses
|
|
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
|
|
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
|
|
to disable memory-checking temporarily.
|
|
|
|
Some inconsistent states that previously were possible (and were
|
|
even the default) are now avoided.
|
|
|
|
-DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
|
|
with each memory chunk allocated; this is occasionally more helpful
|
|
than just having a counter.
|
|
|
|
-DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
|
|
|
|
-DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
|
|
extensions.
|
|
[Bodo Moeller]
|
|
|
|
*) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
|
|
which largely parallels "options", but is for changing API behaviour,
|
|
whereas "options" are about protocol behaviour.
|
|
Initial "mode" flags are:
|
|
|
|
SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
|
|
a single record has been written.
|
|
SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
|
|
retries use the same buffer location.
|
|
(But all of the contents must be
|
|
copied!)
|
|
[Bodo Moeller]
|
|
|
|
*) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
|
|
worked.
|
|
|
|
*) Fix problems with no-hmac etc.
|
|
[Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
|
|
|
|
*) New functions RSA_get_default_method(), RSA_set_method() and
|
|
RSA_get_method(). These allows replacement of RSA_METHODs without having
|
|
to mess around with the internals of an RSA structure.
|
|
[Steve Henson]
|
|
|
|
*) Fix memory leaks in DSA_do_sign and DSA_is_prime.
|
|
Also really enable memory leak checks in openssl.c and in some
|
|
test programs.
|
|
[Chad C. Mulligan, Bodo Moeller]
|
|
|
|
*) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
|
|
up the length of negative integers. This has now been simplified to just
|
|
store the length when it is first determined and use it later, rather
|
|
than trying to keep track of where data is copied and updating it to
|
|
point to the end.
|
|
[Steve Henson, reported by Brien Wheeler
|
|
<bwheeler@authentica-security.com>]
|
|
|
|
*) Add a new function PKCS7_signatureVerify. This allows the verification
|
|
of a PKCS#7 signature but with the signing certificate passed to the
|
|
function itself. This contrasts with PKCS7_dataVerify which assumes the
|
|
certificate is present in the PKCS#7 structure. This isn't always the
|
|
case: certificates can be omitted from a PKCS#7 structure and be
|
|
distributed by "out of band" means (such as a certificate database).
|
|
[Steve Henson]
|
|
|
|
*) Complete the PEM_* macros with DECLARE_PEM versions to replace the
|
|
function prototypes in pem.h, also change util/mkdef.pl to add the
|
|
necessary function names.
|
|
[Steve Henson]
|
|
|
|
*) mk1mf.pl (used by Windows builds) did not properly read the
|
|
options set by Configure in the top level Makefile, and Configure
|
|
was not even able to write more than one option correctly.
|
|
Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
|
|
[Bodo Moeller]
|
|
|
|
*) New functions CONF_load_bio() and CONF_load_fp() to allow a config
|
|
file to be loaded from a BIO or FILE pointer. The BIO version will
|
|
for example allow memory BIOs to contain config info.
|
|
[Steve Henson]
|
|
|
|
*) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
|
|
Whoever hopes to achieve shared-library compatibility across versions
|
|
must use this, not the compile-time macro.
|
|
(Exercise 0.9.4: Which is the minimum library version required by
|
|
such programs?)
|
|
Note: All this applies only to multi-threaded programs, others don't
|
|
need locks.
|
|
[Bodo Moeller]
|
|
|
|
*) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
|
|
through a BIO pair triggered the default case, i.e.
|
|
SSLerr(...,SSL_R_UNKNOWN_STATE).
|
|
[Bodo Moeller]
|
|
|
|
*) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
|
|
can use the SSL library even if none of the specific BIOs is
|
|
appropriate.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
|
|
for the encoded length.
|
|
[Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
|
|
|
|
*) Add initial documentation of the X509V3 functions.
|
|
[Steve Henson]
|
|
|
|
*) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
|
|
PEM_write_bio_PKCS8PrivateKey() that are equivalent to
|
|
PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
|
|
secure PKCS#8 private key format with a high iteration count.
|
|
[Steve Henson]
|
|
|
|
*) Fix determination of Perl interpreter: A perl or perl5
|
|
_directory_ in $PATH was also accepted as the interpreter.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
|
|
wrong with it but it was very old and did things like calling
|
|
PEM_ASN1_read() directly and used MD5 for the hash not to mention some
|
|
unusual formatting.
|
|
[Steve Henson]
|
|
|
|
*) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
|
|
to use the new extension code.
|
|
[Steve Henson]
|
|
|
|
*) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
|
|
with macros. This should make it easier to change their form, add extra
|
|
arguments etc. Fix a few PEM prototypes which didn't have cipher as a
|
|
constant.
|
|
[Steve Henson]
|
|
|
|
*) Add to configuration table a new entry that can specify an alternative
|
|
name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
|
|
according to Mark Crispin <MRC@Panda.COM>.
|
|
[Bodo Moeller]
|
|
|
|
#if 0
|
|
*) DES CBC did not update the IV. Weird.
|
|
[Ben Laurie]
|
|
#else
|
|
des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
|
|
Changing the behaviour of the former might break existing programs --
|
|
where IV updating is needed, des_ncbc_encrypt can be used.
|
|
#endif
|
|
|
|
*) When bntest is run from "make test" it drives bc to check its
|
|
calculations, as well as internally checking them. If an internal check
|
|
fails, it needs to cause bc to give a non-zero result or make test carries
|
|
on without noticing the failure. Fixed.
|
|
[Ben Laurie]
|
|
|
|
*) DES library cleanups.
|
|
[Ulf Möller]
|
|
|
|
*) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
|
|
used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
|
|
ciphers. NOTE: although the key derivation function has been verified
|
|
against some published test vectors it has not been extensively tested
|
|
yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
|
|
of v2.0.
|
|
[Steve Henson]
|
|
|
|
*) Instead of "mkdir -p", which is not fully portable, use new
|
|
Perl script "util/mkdir-p.pl".
|
|
[Bodo Moeller]
|
|
|
|
*) Rewrite the way password based encryption (PBE) is handled. It used to
|
|
assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
|
|
structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
|
|
but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
|
|
the 'parameter' field of the AlgorithmIdentifier is passed to the
|
|
underlying key generation function so it must do its own ASN1 parsing.
|
|
This has also changed the EVP_PBE_CipherInit() function which now has a
|
|
'parameter' argument instead of literal salt and iteration count values
|
|
and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
|
|
[Steve Henson]
|
|
|
|
*) Support for PKCS#5 v1.5 compatible password based encryption algorithms
|
|
and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
|
|
Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
|
|
KEY" because this clashed with PKCS#8 unencrypted string. Since this
|
|
value was just used as a "magic string" and not used directly its
|
|
value doesn't matter.
|
|
[Steve Henson]
|
|
|
|
*) Introduce some semblance of const correctness to BN. Shame C doesn't
|
|
support mutable.
|
|
[Ben Laurie]
|
|
|
|
*) "linux-sparc64" configuration (ultrapenguin).
|
|
[Ray Miller <ray.miller@oucs.ox.ac.uk>]
|
|
"linux-sparc" configuration.
|
|
[Christian Forster <fo@hawo.stw.uni-erlangen.de>]
|
|
|
|
*) config now generates no-xxx options for missing ciphers.
|
|
[Ulf Möller]
|
|
|
|
*) Support the EBCDIC character set (work in progress).
|
|
File ebcdic.c not yet included because it has a different license.
|
|
[Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
|
|
|
|
*) Support BS2000/OSD-POSIX.
|
|
[Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
|
|
|
|
*) Make callbacks for key generation use void * instead of char *.
|
|
[Ben Laurie]
|
|
|
|
*) Make S/MIME samples compile (not yet tested).
|
|
[Ben Laurie]
|
|
|
|
*) Additional typesafe stacks.
|
|
[Ben Laurie]
|
|
|
|
*) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
|
|
[Bodo Moeller]
|
|
|
|
|
|
Changes between 0.9.3 and 0.9.3a [29 May 1999]
|
|
|
|
*) New configuration variant "sco5-gcc".
|
|
|
|
*) Updated some demos.
|
|
[Sean O Riordain, Wade Scholine]
|
|
|
|
*) Add missing BIO_free at exit of pkcs12 application.
|
|
[Wu Zhigang]
|
|
|
|
*) Fix memory leak in conf.c.
|
|
[Steve Henson]
|
|
|
|
*) Updates for Win32 to assembler version of MD5.
|
|
[Steve Henson]
|
|
|
|
*) Set #! path to perl in apps/der_chop to where we found it
|
|
instead of using a fixed path.
|
|
[Bodo Moeller]
|
|
|
|
*) SHA library changes for irix64-mips4-cc.
|
|
[Andy Polyakov]
|
|
|
|
*) Improvements for VMS support.
|
|
[Richard Levitte]
|
|
|
|
|
|
Changes between 0.9.2b and 0.9.3 [24 May 1999]
|
|
|
|
*) Bignum library bug fix. IRIX 6 passes "make test" now!
|
|
This also avoids the problems with SC4.2 and unpatched SC5.
|
|
[Andy Polyakov <appro@fy.chalmers.se>]
|
|
|
|
*) New functions sk_num, sk_value and sk_set to replace the previous macros.
|
|
These are required because of the typesafe stack would otherwise break
|
|
existing code. If old code used a structure member which used to be STACK
|
|
and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
|
|
sk_num or sk_value it would produce an error because the num, data members
|
|
are not present in STACK_OF. Now it just produces a warning. sk_set
|
|
replaces the old method of assigning a value to sk_value
|
|
(e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
|
|
that does this will no longer work (and should use sk_set instead) but
|
|
this could be regarded as a "questionable" behaviour anyway.
|
|
[Steve Henson]
|
|
|
|
*) Fix most of the other PKCS#7 bugs. The "experimental" code can now
|
|
correctly handle encrypted S/MIME data.
|
|
[Steve Henson]
|
|
|
|
*) Change type of various DES function arguments from des_cblock
|
|
(which means, in function argument declarations, pointer to char)
|
|
to des_cblock * (meaning pointer to array with 8 char elements),
|
|
which allows the compiler to do more typechecking; it was like
|
|
that back in SSLeay, but with lots of ugly casts.
|
|
|
|
Introduce new type const_des_cblock.
|
|
[Bodo Moeller]
|
|
|
|
*) Reorganise the PKCS#7 library and get rid of some of the more obvious
|
|
problems: find RecipientInfo structure that matches recipient certificate
|
|
and initialise the ASN1 structures properly based on passed cipher.
|
|
[Steve Henson]
|
|
|
|
*) Belatedly make the BN tests actually check the results.
|
|
[Ben Laurie]
|
|
|
|
*) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
|
|
to and from BNs: it was completely broken. New compilation option
|
|
NEG_PUBKEY_BUG to allow for some broken certificates that encode public
|
|
key elements as negative integers.
|
|
[Steve Henson]
|
|
|
|
*) Reorganize and speed up MD5.
|
|
[Andy Polyakov <appro@fy.chalmers.se>]
|
|
|
|
*) VMS support.
|
|
[Richard Levitte <richard@levitte.org>]
|
|
|
|
*) New option -out to asn1parse to allow the parsed structure to be
|
|
output to a file. This is most useful when combined with the -strparse
|
|
option to examine the output of things like OCTET STRINGS.
|
|
[Steve Henson]
|
|
|
|
*) Make SSL library a little more fool-proof by not requiring any longer
|
|
that SSL_set_{accept,connect}_state be called before
|
|
SSL_{accept,connect} may be used (SSL_set_..._state is omitted
|
|
in many applications because usually everything *appeared* to work as
|
|
intended anyway -- now it really works as intended).
|
|
[Bodo Moeller]
|
|
|
|
*) Move openssl.cnf out of lib/.
|
|
[Ulf Möller]
|
|
|
|
*) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
|
|
-Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
|
|
-Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Various fixes to the EVP and PKCS#7 code. It may now be able to
|
|
handle PKCS#7 enveloped data properly.
|
|
[Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
|
|
|
|
*) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
|
|
copying pointers. The cert_st handling is changed by this in
|
|
various ways (and thus what used to be known as ctx->default_cert
|
|
is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
|
|
any longer when s->cert does not give us what we need).
|
|
ssl_cert_instantiate becomes obsolete by this change.
|
|
As soon as we've got the new code right (possibly it already is?),
|
|
we have solved a couple of bugs of the earlier code where s->cert
|
|
was used as if it could not have been shared with other SSL structures.
|
|
|
|
Note that using the SSL API in certain dirty ways now will result
|
|
in different behaviour than observed with earlier library versions:
|
|
Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
|
|
does not influence s as it used to.
|
|
|
|
In order to clean up things more thoroughly, inside SSL_SESSION
|
|
we don't use CERT any longer, but a new structure SESS_CERT
|
|
that holds per-session data (if available); currently, this is
|
|
the peer's certificate chain and, for clients, the server's certificate
|
|
and temporary key. CERT holds only those values that can have
|
|
meaningful defaults in an SSL_CTX.
|
|
[Bodo Moeller]
|
|
|
|
*) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
|
|
from the internal representation. Various PKCS#7 fixes: remove some
|
|
evil casts and set the enc_dig_alg field properly based on the signing
|
|
key type.
|
|
[Steve Henson]
|
|
|
|
*) Allow PKCS#12 password to be set from the command line or the
|
|
environment. Let 'ca' get its config file name from the environment
|
|
variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
|
|
and 'x509').
|
|
[Steve Henson]
|
|
|
|
*) Allow certificate policies extension to use an IA5STRING for the
|
|
organization field. This is contrary to the PKIX definition but
|
|
VeriSign uses it and IE5 only recognises this form. Document 'x509'
|
|
extension option.
|
|
[Steve Henson]
|
|
|
|
*) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
|
|
without disallowing inline assembler and the like for non-pedantic builds.
|
|
[Ben Laurie]
|
|
|
|
*) Support Borland C++ builder.
|
|
[Janez Jere <jj@void.si>, modified by Ulf Möller]
|
|
|
|
*) Support Mingw32.
|
|
[Ulf Möller]
|
|
|
|
*) SHA-1 cleanups and performance enhancements.
|
|
[Andy Polyakov <appro@fy.chalmers.se>]
|
|
|
|
*) Sparc v8plus assembler for the bignum library.
|
|
[Andy Polyakov <appro@fy.chalmers.se>]
|
|
|
|
*) Accept any -xxx and +xxx compiler options in Configure.
|
|
[Ulf Möller]
|
|
|
|
*) Update HPUX configuration.
|
|
[Anonymous]
|
|
|
|
*) Add missing sk_<type>_unshift() function to safestack.h
|
|
[Ralf S. Engelschall]
|
|
|
|
*) New function SSL_CTX_use_certificate_chain_file that sets the
|
|
"extra_cert"s in addition to the certificate. (This makes sense
|
|
only for "PEM" format files, as chains as a whole are not
|
|
DER-encoded.)
|
|
[Bodo Moeller]
|
|
|
|
*) Support verify_depth from the SSL API.
|
|
x509_vfy.c had what can be considered an off-by-one-error:
|
|
Its depth (which was not part of the external interface)
|
|
was actually counting the number of certificates in a chain;
|
|
now it really counts the depth.
|
|
[Bodo Moeller]
|
|
|
|
*) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
|
|
instead of X509err, which often resulted in confusing error
|
|
messages since the error codes are not globally unique
|
|
(e.g. an alleged error in ssl3_accept when a certificate
|
|
didn't match the private key).
|
|
|
|
*) New function SSL_CTX_set_session_id_context that allows to set a default
|
|
value (so that you don't need SSL_set_session_id_context for each
|
|
connection using the SSL_CTX).
|
|
[Bodo Moeller]
|
|
|
|
*) OAEP decoding bug fix.
|
|
[Ulf Möller]
|
|
|
|
*) Support INSTALL_PREFIX for package builders, as proposed by
|
|
David Harris.
|
|
[Bodo Moeller]
|
|
|
|
*) New Configure options "threads" and "no-threads". For systems
|
|
where the proper compiler options are known (currently Solaris
|
|
and Linux), "threads" is the default.
|
|
[Bodo Moeller]
|
|
|
|
*) New script util/mklink.pl as a faster substitute for util/mklink.sh.
|
|
[Bodo Moeller]
|
|
|
|
*) Install various scripts to $(OPENSSLDIR)/misc, not to
|
|
$(INSTALLTOP)/bin -- they shouldn't clutter directories
|
|
such as /usr/local/bin.
|
|
[Bodo Moeller]
|
|
|
|
*) "make linux-shared" to build shared libraries.
|
|
[Niels Poppe <niels@netbox.org>]
|
|
|
|
*) New Configure option no-<cipher> (rsa, idea, rc5, ...).
|
|
[Ulf Möller]
|
|
|
|
*) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
|
|
extension adding in x509 utility.
|
|
[Steve Henson]
|
|
|
|
*) Remove NOPROTO sections and error code comments.
|
|
[Ulf Möller]
|
|
|
|
*) Partial rewrite of the DEF file generator to now parse the ANSI
|
|
prototypes.
|
|
[Steve Henson]
|
|
|
|
*) New Configure options --prefix=DIR and --openssldir=DIR.
|
|
[Ulf Möller]
|
|
|
|
*) Complete rewrite of the error code script(s). It is all now handled
|
|
by one script at the top level which handles error code gathering,
|
|
header rewriting and C source file generation. It should be much better
|
|
than the old method: it now uses a modified version of Ulf's parser to
|
|
read the ANSI prototypes in all header files (thus the old K&R definitions
|
|
aren't needed for error creation any more) and do a better job of
|
|
translating function codes into names. The old 'ASN1 error code embedded
|
|
in a comment' is no longer necessary and it doesn't use .err files which
|
|
have now been deleted. Also the error code call doesn't have to appear all
|
|
on one line (which resulted in some large lines...).
|
|
[Steve Henson]
|
|
|
|
*) Change #include filenames from <foo.h> to <openssl/foo.h>.
|
|
[Bodo Moeller]
|
|
|
|
*) Change behaviour of ssl2_read when facing length-0 packets: Don't return
|
|
0 (which usually indicates a closed connection), but continue reading.
|
|
[Bodo Moeller]
|
|
|
|
*) Fix some race conditions.
|
|
[Bodo Moeller]
|
|
|
|
*) Add support for CRL distribution points extension. Add Certificate
|
|
Policies and CRL distribution points documentation.
|
|
[Steve Henson]
|
|
|
|
*) Move the autogenerated header file parts to crypto/opensslconf.h.
|
|
[Ulf Möller]
|
|
|
|
*) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
|
|
8 of keying material. Merlin has also confirmed interop with this fix
|
|
between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
|
|
[Merlin Hughes <merlin@baltimore.ie>]
|
|
|
|
*) Fix lots of warnings.
|
|
[Richard Levitte <levitte@stacken.kth.se>]
|
|
|
|
*) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
|
|
the directory spec didn't end with a LIST_SEPARATOR_CHAR.
|
|
[Richard Levitte <levitte@stacken.kth.se>]
|
|
|
|
*) Fix problems with sizeof(long) == 8.
|
|
[Andy Polyakov <appro@fy.chalmers.se>]
|
|
|
|
*) Change functions to ANSI C.
|
|
[Ulf Möller]
|
|
|
|
*) Fix typos in error codes.
|
|
[Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
|
|
|
|
*) Remove defunct assembler files from Configure.
|
|
[Ulf Möller]
|
|
|
|
*) SPARC v8 assembler BIGNUM implementation.
|
|
[Andy Polyakov <appro@fy.chalmers.se>]
|
|
|
|
*) Support for Certificate Policies extension: both print and set.
|
|
Various additions to support the r2i method this uses.
|
|
[Steve Henson]
|
|
|
|
*) A lot of constification, and fix a bug in X509_NAME_oneline() that could
|
|
return a const string when you are expecting an allocated buffer.
|
|
[Ben Laurie]
|
|
|
|
*) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
|
|
types DirectoryString and DisplayText.
|
|
[Steve Henson]
|
|
|
|
*) Add code to allow r2i extensions to access the configuration database,
|
|
add an LHASH database driver and add several ctx helper functions.
|
|
[Steve Henson]
|
|
|
|
*) Fix an evil bug in bn_expand2() which caused various BN functions to
|
|
fail when they extended the size of a BIGNUM.
|
|
[Steve Henson]
|
|
|
|
*) Various utility functions to handle SXNet extension. Modify mkdef.pl to
|
|
support typesafe stack.
|
|
[Steve Henson]
|
|
|
|
*) Fix typo in SSL_[gs]et_options().
|
|
[Nils Frostberg <nils@medcom.se>]
|
|
|
|
*) Delete various functions and files that belonged to the (now obsolete)
|
|
old X509V3 handling code.
|
|
[Steve Henson]
|
|
|
|
*) New Configure option "rsaref".
|
|
[Ulf Möller]
|
|
|
|
*) Don't auto-generate pem.h.
|
|
[Bodo Moeller]
|
|
|
|
*) Introduce type-safe ASN.1 SETs.
|
|
[Ben Laurie]
|
|
|
|
*) Convert various additional casted stacks to type-safe STACK_OF() variants.
|
|
[Ben Laurie, Ralf S. Engelschall, Steve Henson]
|
|
|
|
*) Introduce type-safe STACKs. This will almost certainly break lots of code
|
|
that links with OpenSSL (well at least cause lots of warnings), but fear
|
|
not: the conversion is trivial, and it eliminates loads of evil casts. A
|
|
few STACKed things have been converted already. Feel free to convert more.
|
|
In the fullness of time, I'll do away with the STACK type altogether.
|
|
[Ben Laurie]
|
|
|
|
*) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
|
|
specified in <certfile> by updating the entry in the index.txt file.
|
|
This way one no longer has to edit the index.txt file manually for
|
|
revoking a certificate. The -revoke option does the gory details now.
|
|
[Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
|
|
|
|
*) Fix `openssl crl -noout -text' combination where `-noout' killed the
|
|
`-text' option at all and this way the `-noout -text' combination was
|
|
inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Make sure a corresponding plain text error message exists for the
|
|
X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
|
|
verify callback function determined that a certificate was revoked.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Bugfix: In test/testenc, don't test "openssl <cipher>" for
|
|
ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
|
|
all available ciphers including rc5, which was forgotten until now.
|
|
In order to let the testing shell script know which algorithms
|
|
are available, a new (up to now undocumented) command
|
|
"openssl list-cipher-commands" is used.
|
|
[Bodo Moeller]
|
|
|
|
*) Bugfix: s_client occasionally would sleep in select() when
|
|
it should have checked SSL_pending() first.
|
|
[Bodo Moeller]
|
|
|
|
*) New functions DSA_do_sign and DSA_do_verify to provide access to
|
|
the raw DSA values prior to ASN.1 encoding.
|
|
[Ulf Möller]
|
|
|
|
*) Tweaks to Configure
|
|
[Niels Poppe <niels@netbox.org>]
|
|
|
|
*) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
|
|
yet...
|
|
[Steve Henson]
|
|
|
|
*) New variables $(RANLIB) and $(PERL) in the Makefiles.
|
|
[Ulf Möller]
|
|
|
|
*) New config option to avoid instructions that are illegal on the 80386.
|
|
The default code is faster, but requires at least a 486.
|
|
[Ulf Möller]
|
|
|
|
*) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
|
|
SSL2_SERVER_VERSION (not used at all) macros, which are now the
|
|
same as SSL2_VERSION anyway.
|
|
[Bodo Moeller]
|
|
|
|
*) New "-showcerts" option for s_client.
|
|
[Bodo Moeller]
|
|
|
|
*) Still more PKCS#12 integration. Add pkcs12 application to openssl
|
|
application. Various cleanups and fixes.
|
|
[Steve Henson]
|
|
|
|
*) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
|
|
modify error routines to work internally. Add error codes and PBE init
|
|
to library startup routines.
|
|
[Steve Henson]
|
|
|
|
*) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
|
|
packing functions to asn1 and evp. Changed function names and error
|
|
codes along the way.
|
|
[Steve Henson]
|
|
|
|
*) PKCS12 integration: and so it begins... First of several patches to
|
|
slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
|
|
objects to objects.h
|
|
[Steve Henson]
|
|
|
|
*) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
|
|
and display support for Thawte strong extranet extension.
|
|
[Steve Henson]
|
|
|
|
*) Add LinuxPPC support.
|
|
[Jeff Dubrule <igor@pobox.org>]
|
|
|
|
*) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
|
|
bn_div_words in alpha.s.
|
|
[Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
|
|
|
|
*) Make sure the RSA OAEP test is skipped under -DRSAref because
|
|
OAEP isn't supported when OpenSSL is built with RSAref.
|
|
[Ulf Moeller <ulf@fitug.de>]
|
|
|
|
*) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
|
|
so they no longer are missing under -DNOPROTO.
|
|
[Soren S. Jorvang <soren@t.dk>]
|
|
|
|
|
|
Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
|
|
|
|
*) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
|
|
doesn't work when the session is reused. Coming soon!
|
|
[Ben Laurie]
|
|
|
|
*) Fix a security hole, that allows sessions to be reused in the wrong
|
|
context thus bypassing client cert protection! All software that uses
|
|
client certs and session caches in multiple contexts NEEDS PATCHING to
|
|
allow session reuse! A fuller solution is in the works.
|
|
[Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
|
|
|
|
*) Some more source tree cleanups (removed obsolete files
|
|
crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
|
|
permission on "config" script to be executable) and a fix for the INSTALL
|
|
document.

|
[Ulf Moeller <ulf@fitug.de>]
|
|
|
|
*) Remove some legacy and erroneous uses of malloc, free instead of
|
|
Malloc, Free.
|
|
[Lennart Bang <lob@netstream.se>, with minor changes by Steve]
|
|
|
|
*) Make rsa_oaep_test return non-zero on error.
|
|
[Ulf Moeller <ulf@fitug.de>]
|
|
|
|
*) Add support for native Solaris shared libraries. Configure
|
|
solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
|
|
if someone would make that last step automatic.
|
|
[Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
|
|
|
|
*) ctx_size was not built with the right compiler during "make links". Fixed.
|
|
[Ben Laurie]
|
|
|
|
*) Change the meaning of 'ALL' in the cipher list. It now means "everything
|
|
except NULL ciphers". This means the default cipher list will no longer
|
|
enable NULL ciphers. They need to be specifically enabled e.g. with
|
|
the string "DEFAULT:eNULL".
|
|
[Steve Henson]
|
|
|
|
*) Fix to RSA private encryption routines: if p < q then it would
|
|
occasionally produce an invalid result. This will only happen with
|
|
externally generated keys because OpenSSL (and SSLeay) ensure p > q.
|
|
[Steve Henson]
|
|
|
|
*) Be less restrictive and allow also `perl util/perlpath.pl
|
|
/path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
|
|
because this way one can also use an interpreter named `perl5' (which is
|
|
usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
|
|
installed as `perl').
|
|
[Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
|
|
|
|
*) Let util/clean-depend.pl work also with older Perl 5.00x versions.
|
|
[Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
|
|
|
|
*) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
|
|
advapi32.lib to Win32 build and change the pem test comparison
|
|
to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
|
|
suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
|
|
and crypto/des/ede_cbcm_enc.c.
|
|
[Steve Henson]
|
|
|
|
*) DES quad checksum was broken on big-endian architectures. Fixed.
|
|
[Ben Laurie]
|
|
|
|
*) Comment out two functions in bio.h that aren't implemented. Fix up the
|
|
Win32 test batch file so it (might) work again. The Win32 test batch file
|
|
is horrible: I feel ill....
|
|
[Steve Henson]
|
|
|
|
*) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
|
|
in e_os.h. Audit of header files to check ANSI and non ANSI
|
|
sections: 10 functions were absent from non ANSI section and not exported
|
|
from Windows DLLs. Fixed up libeay.num for new functions.
|
|
[Steve Henson]
|
|
|
|
*) Make `openssl version' output lines consistent.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Fix Win32 symbol export lists for BIO functions: Added
|
|
BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
|
|
to ms/libeay{16,32}.def.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
|
|
fine under Unix and passes some trivial tests I've now added. But the
|
|
whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
|
|
added to make sure no one expects that this stuff really works in the
|
|
OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
|
|
up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
|
|
openssl_bio.xs.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Fix the generation of two part addresses in perl.
|
|
[Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
|
|
|
|
*) Add config entry for Linux on MIPS.
|
|
[John Tobey <jtobey@channel1.com>]
|
|
|
|
*) Make links whenever Configure is run, unless we are on Windoze.
|
|
[Ben Laurie]
|
|
|
|
*) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
|
|
Currently only issuerAltName and AuthorityKeyIdentifier make any sense
|
|
in CRLs.
|
|
[Steve Henson]
|
|
|
|
*) Add a useful kludge to allow package maintainers to specify compiler and
|
|
other platforms details on the command line without having to patch the
|
|
Configure script every time: One now can use ``perl Configure
|
|
<id>:<details>'', i.e. platform ids are allowed to have details appended
|
|
to them (separated by colons). This is treated as there would be a static
|
|
pre-configured entry in Configure's %table under key <id> with value
|
|
<details> and ``perl Configure <id>'' is called. So, when you want to
|
|
perform a quick test-compile under FreeBSD 3.1 with pgcc and without
|
|
assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
|
|
now, which overrides the FreeBSD-elf entry on-the-fly.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Disable new TLS1 ciphersuites by default: they aren't official yet.
|
|
[Ben Laurie]
|
|
|
|
*) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
|
|
on the `perl Configure ...' command line. This way one can compile
|
|
OpenSSL libraries with Position Independent Code (PIC) which is needed
|
|
for linking it into DSOs.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Remarkably, export ciphers were totally broken and no-one had noticed!
|
|
Fixed.
|
|
[Ben Laurie]
|
|
|
|
*) Cleaned up the LICENSE document: The official contact for any license
|
|
questions now is the OpenSSL core team under openssl-core@openssl.org.
|
|
And add a paragraph about the dual-license situation to make sure people
|
|
recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
|
|
to the OpenSSL toolkit.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) General source tree makefile cleanups: Made `making xxx in yyy...'
|
|
display consistent in the source tree and replaced `/bin/rm' by `rm'.
|
|
Additionally cleaned up the `make links' target: Remove unnecessary
|
|
semicolons, subsequent redundant removes, inline point.sh into mklink.sh
|
|
to speed processing and no longer clutter the display with confusing
|
|
stuff. Instead only the actually done links are displayed.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Permit null encryption ciphersuites, used for authentication only. It used
|
|
to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
|
|
It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
|
|
encryption.
|
|
[Ben Laurie]
|
|
|
|
*) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
|
|
signed attributes when verifying signatures (this would break them),
|
|
the detached data encoding was wrong and public keys obtained using
|
|
X509_get_pubkey() weren't freed.
|
|
[Steve Henson]
|
|
|
|
*) Add text documentation for the BUFFER functions. Also added a work around
|
|
to a Win95 console bug. This was triggered by the password read stuff: the
|
|
last character typed gets carried over to the next fread(). If you were
|
|
generating a new cert request using 'req' for example then the last
|
|
character of the passphrase would be CR which would then enter the first
|
|
field as blank.
|
|
[Steve Henson]
|
|
|
|
*) Added the new `Includes OpenSSL Cryptography Software' button as
|
|
doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
|
|
button and can be used by applications based on OpenSSL to show the
|
|
relationship to the OpenSSL project.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Remove confusing variables in function signatures in files
|
|
ssl/ssl_lib.c and ssl/ssl.h.
|
|
[Lennart Bong <lob@kulthea.stacken.kth.se>]
|
|
|
|
*) Don't install bss_file.c under PREFIX/include/
|
|
[Lennart Bong <lob@kulthea.stacken.kth.se>]
|
|
|
|
*) Get the Win32 compile working again. Modify mkdef.pl so it can handle
|
|
functions that return function pointers and has support for NT specific
|
|
stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
|
|
#ifdef WIN32 and WINNTs sprinkled about the place and some changes from
|
|
unsigned to signed types: this was killing the Win32 compile.
|
|
[Steve Henson]
|
|
|
|
*) Add new certificate file to stack functions,
|
|
SSL_add_dir_cert_subjects_to_stack() and
|
|
SSL_add_file_cert_subjects_to_stack(). These largely supplant
|
|
SSL_load_client_CA_file(), and can be used to add multiple certs easily
|
|
to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
|
|
This means that Apache-SSL and similar packages don't have to mess around
|
|
to add as many CAs as they want to the preferred list.
|
|
[Ben Laurie]
|
|
|
|
*) Experiment with doxygen documentation. Currently only partially applied to
|
|
ssl/ssl_lib.c.
|
|
See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
|
|
openssl.doxy as the configuration file.
|
|
[Ben Laurie]
|
|
|
|
*) Get rid of remaining C++-style comments which strict C compilers hate.
|
|
[Ralf S. Engelschall, pointed out by Carlos Amengual]
|
|
|
|
*) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
|
|
compiled in by default: it has problems with large keys.
|
|
[Steve Henson]
|
|
|
|
*) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
|
|
DH private keys and/or callback functions which directly correspond to
|
|
their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
|
|
is needed for applications which have to configure certificates on a
|
|
per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
|
|
(e.g. s_server).
|
|
For the RSA certificate situation is makes no difference, but
|
|
for the DSA certificate situation this fixes the "no shared cipher"
|
|
problem where the OpenSSL cipher selection procedure failed because the
|
|
temporary keys were not overtaken from the context and the API provided
|
|
no way to reconfigure them.
|
|
The new functions now let applications reconfigure the stuff and they
|
|
are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
|
|
SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
|
|
non-public-API function ssl_cert_instantiate() is used as a helper
|
|
function and also to reduce code redundancy inside ssl_rsa.c.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Move s_server -dcert and -dkey options out of the undocumented feature
|
|
area because they are useful for the DSA situation and should be
|
|
recognized by the users.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Fix the cipher decision scheme for export ciphers: the export bits are
|
|
*not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
|
|
SSL_EXP_MASK. So, the original variable has to be used instead of the
|
|
already masked variable.
|
|
[Richard Levitte <levitte@stacken.kth.se>]
|
|
|
|
*) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
|
|
[Richard Levitte <levitte@stacken.kth.se>]
|
|
|
|
*) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
|
|
from `int' to `unsigned int' because it's a length and initialized by
|
|
EVP_DigestFinal() which expects an `unsigned int *'.
|
|
[Richard Levitte <levitte@stacken.kth.se>]
|
|
|
|
*) Don't hard-code path to Perl interpreter on shebang line of Configure
|
|
script. Instead use the usual Shell->Perl transition trick.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Make `openssl x509 -noout -modulus' functional also for DSA certificates
|
|
(in addition to RSA certificates) to match the behaviour of `openssl dsa
|
|
-noout -modulus' as it's already the case for `openssl rsa -noout
|
|
-modulus'. For RSA the -modulus is the real "modulus" while for DSA
|
|
currently the public key is printed (a decision which was already done by
|
|
`openssl dsa -modulus' in the past) which serves a similar purpose.
|
|
Additionally the NO_RSA no longer completely removes the whole -modulus
|
|
option; it now only avoids using the RSA stuff. Same applies to NO_DSA
|
|
now, too.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
|
|
BIO. See the source (crypto/evp/bio_ok.c) for more info.
|
|
[Arne Ansper <arne@ats.cyber.ee>]
|
|
|
|
*) Dump the old yucky req code that tried (and failed) to allow raw OIDs
|
|
to be added. Now both 'req' and 'ca' can use new objects defined in the
|
|
config file.
|
|
[Steve Henson]
|
|
|
|
*) Add cool BIO that does syslog (or event log on NT).
|
|
[Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
|
|
|
|
*) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
|
|
TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
|
|
TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
|
|
Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
|
|
[Ben Laurie]
|
|
|
|
*) Add preliminary config info for new extension code.
|
|
[Steve Henson]
|
|
|
|
*) Make RSA_NO_PADDING really use no padding.
|
|
[Ulf Moeller <ulf@fitug.de>]
|
|
|
|
*) Generate errors when private/public key check is done.
|
|
[Ben Laurie]
|
|
|
|
*) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
|
|
for some CRL extensions and new objects added.
|
|
[Steve Henson]
|
|
|
|
*) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
|
|
key usage extension and fuller support for authority key id.
|
|
[Steve Henson]
|
|
|
|
*) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
|
|
padding method for RSA, which is recommended for new applications in PKCS
|
|
#1 v2.0 (RFC 2437, October 1998).
|
|
OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
|
|
foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
|
|
against Bleichbacher's attack on RSA.
|
|
[Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
|
|
Ben Laurie]
|
|
|
|
*) Updates to the new SSL compression code
|
|
[Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
|
|
|
|
*) Fix so that the version number in the master secret, when passed
|
|
via RSA, checks that if TLS was proposed, but we roll back to SSLv3
|
|
(because the server will not accept higher), that the version number
|
|
is 0x03,0x01, not 0x03,0x00
|
|
[Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
|
|
|
|
*) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
|
|
leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
|
|
in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
|
|
[Steve Henson]
|
|
|
|
*) Support for RAW extensions where an arbitrary extension can be
|
|
created by including its DER encoding. See apps/openssl.cnf for
|
|
an example.
|
|
[Steve Henson]
|
|
|
|
*) Make sure latest Perl versions don't interpret some generated C array
|
|
code as Perl array code in the crypto/err/err_genc.pl script.
|
|
[Lars Weber <3weber@informatik.uni-hamburg.de>]
|
|
|
|
*) Modify ms/do_ms.bat to not generate assembly language makefiles since
|
|
not many people have the assembler. Various Win32 compilation fixes and
|
|
update to the INSTALL.W32 file with (hopefully) more accurate Win32
|
|
build instructions.
|
|
[Steve Henson]
|
|
|
|
*) Modify configure script 'Configure' to automatically create crypto/date.h
|
|
file under Win32 and also build pem.h from pem.org. New script
|
|
util/mkfiles.pl to create the MINFO file on environments that can't do a
|
|
'make files': perl util/mkfiles.pl >MINFO should work.
|
|
[Steve Henson]
|
|
|
|
*) Major rework of DES function declarations, in the pursuit of correctness
|
|
and purity. As a result, many evil casts evaporated, and some weirdness,
|
|
too. You may find this causes warnings in your code. Zapping your evil
|
|
casts will probably fix them. Mostly.
|
|
[Ben Laurie]
|
|
|
|
*) Fix for a typo in asn1.h. Bug fix to object creation script
|
|
obj_dat.pl. It considered a zero in an object definition to mean
|
|
"end of object": none of the objects in objects.h have any zeros
|
|
so it wasn't spotted.
|
|
[Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
|
|
|
|
*) Add support for Triple DES Cipher Block Chaining with Output Feedback
|
|
Masking (CBCM). In the absence of test vectors, the best I have been able
|
|
to do is check that the decrypt undoes the encrypt, so far. Send me test
|
|
vectors if you have them.
|
|
[Ben Laurie]
|
|
|
|
*) Correct calculation of key length for export ciphers (too much space was
|
|
allocated for null ciphers). This has not been tested!
|
|
[Ben Laurie]
|
|
|
|
*) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
|
|
message is now correct (it understands "crypto" and "ssl" on its
|
|
command line). There is also now an "update" option. This will update
|
|
the util/ssleay.num and util/libeay.num files with any new functions.
|
|
If you do a:
|
|
perl util/mkdef.pl crypto ssl update
|
|
it will update them.
|
|
[Steve Henson]
|
|
|
|
*) Overhauled the Perl interface (perl/*):
|
|
- ported BN stuff to OpenSSL's different BN library
|
|
- made the perl/ source tree CVS-aware
|
|
- renamed the package from SSLeay to OpenSSL (the files still contain
|
|
their history because I've copied them in the repository)
|
|
- removed obsolete files (the test scripts will be replaced
|
|
by better Test::Harness variants in the future)
|
|
[Ralf S. Engelschall]
|
|
|
|
*) First cut for a very conservative source tree cleanup:
|
|
1. merge various obsolete readme texts into doc/ssleay.txt
|
|
where we collect the old documents and readme texts.
|
|
2. remove the first part of files where I'm already sure that we no
|
|
longer need them because of three reasons: either they are just temporary
|
|
files which were left by Eric or they are preserved original files where
|
|
I've verified that the diff is also available in the CVS via "cvs diff
|
|
-rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
|
|
the crypto/md/ stuff).
|
|
[Ralf S. Engelschall]
|
|
|
|
*) More extension code. Incomplete support for subject and issuer alt
|
|
name, issuer and authority key id. Change the i2v function parameters
|
|
and add an extra 'crl' parameter in the X509V3_CTX structure: guess
|
|
what that's for :-) Fix to ASN1 macro which messed up
|
|
IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
|
|
[Steve Henson]
|
|
|
|
*) Preliminary support for ENUMERATED type. This is largely copied from the
|
|
INTEGER code.
|
|
[Steve Henson]
|
|
|
|
*) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
|
|
[Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
|
|
|
|
*) Make sure `make rehash' target really finds the `openssl' program.
|
|
[Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
|
|
|
|
*) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
|
|
like to hear about it if this slows down other processors.
|
|
[Ben Laurie]
|
|
|
|
*) Add CygWin32 platform information to Configure script.
|
|
[Alan Batie <batie@aahz.jf.intel.com>]
|
|
|
|
*) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
|
|
[Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
|
|
|
|
*) New program nseq to manipulate netscape certificate sequences
|
|
[Steve Henson]
|
|
|
|
*) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
|
|
few typos.
|
|
[Steve Henson]
|
|
|
|
*) Fixes to BN code. Previously the default was to define BN_RECURSION
|
|
but the BN code had some problems that would cause failures when
|
|
doing certificate verification and some other functions.
|
|
[Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
|
|
|
|
*) Add ASN1 and PEM code to support netscape certificate sequences.
|
|
[Steve Henson]
|
|
|
|
*) Add ASN1 and PEM code to support netscape certificate sequences.
|
|
[Steve Henson]
|
|
|
|
*) Add several PKIX and private extended key usage OIDs.
|
|
[Steve Henson]
|
|
|
|
*) Modify the 'ca' program to handle the new extension code. Modify
|
|
openssl.cnf for new extension format, add comments.
|
|
[Steve Henson]
|
|
|
|
*) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
|
|
and add a sample to openssl.cnf so req -x509 now adds appropriate
|
|
CA extensions.
|
|
[Steve Henson]
|
|
|
|
*) Continued X509 V3 changes. Add to other makefiles, integrate with the
|
|
error code, add initial support to X509_print() and x509 application.
|
|
[Steve Henson]
|
|
|
|
*) Takes a deep breath and start adding X509 V3 extension support code. Add
|
|
files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
|
|
stuff is currently isolated and isn't even compiled yet.
|
|
[Steve Henson]
|
|
|
|
*) Continuing patches for GeneralizedTime. Fix up certificate and CRL
|
|
ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
|
|
Removed the versions check from X509 routines when loading extensions:
|
|
this allows certain broken certificates that don't set the version
|
|
properly to be processed.

|
|
|
*) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
|
|
Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
|
|
can still be regenerated with "make depend".
|
|
[Ben Laurie]
|
|
|
|
*) Spelling mistake in C version of CAST-128.
|
|
[Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
|
|
|
|
*) Changes to the error generation code. The perl script err-code.pl
|
|
now reads in the old error codes and retains the old numbers, only
|
|
adding new ones if necessary. It also only changes the .err files if new
|
|
codes are added. The makefiles have been modified to only insert errors
|
|
when needed (to avoid needlessly modifying header files). This is done
|
|
by only inserting errors if the .err file is newer than the auto generated
|
|
C file. To rebuild all the error codes from scratch (the old behaviour)
|
|
either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
|
|
or delete all the .err files.
|
|
[Steve Henson]
|
|
|
|
*) CAST-128 was incorrectly implemented for short keys. The C version has
|
|
been fixed, but is untested. The assembler versions are also fixed, but
|
|
new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
|
|
to regenerate it if needed.
|
|
[Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun

|
Hagino <itojun@kame.net>]
|
|
|
|
*) File was opened incorrectly in randfile.c.
|
|
[Ulf Möller <ulf@fitug.de>]
|
|
|
|
*) Beginning of support for GeneralizedTime. d2i, i2d, check and print
|
|
functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
|
|
GeneralizedTime. ASN1_TIME is the proper type used in certificates et
|
|
al: it's just almost always a UTCTime. Note this patch adds new error
|
|
codes so do a "make errors" if there are problems.
|
|
[Steve Henson]
|
|
|
|
*) Correct Linux 1 recognition in config.
|
|
[Ulf Möller <ulf@fitug.de>]
|
|
|
|
*) Remove pointless MD5 hash when using DSA keys in ca.
|
|
[Anonymous <nobody@replay.com>]
|
|
|
|
*) Generate an error if given an empty string as a cert directory. Also
|
|
generate an error if handed NULL (previously returned 0 to indicate an
|
|
error, but didn't set one).
|
|
[Ben Laurie, reported by Anonymous <nobody@replay.com>]
|
|
|
|
*) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
|
|
[Ben Laurie]
|
|
|
|
*) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
|
|
parameters. This was causing a warning which killed off the Win32 compile.
|
|
[Steve Henson]
|
|
|
|
*) Remove C++ style comments from crypto/bn/bn_local.h.
|
|
[Neil Costigan <neil.costigan@celocom.com>]
|
|
|
|
*) The function OBJ_txt2nid was broken. It was supposed to return a nid
|
|
based on a text string, looking up short and long names and finally
|
|
"dot" format. The "dot" format stuff didn't work. Added new function
|
|
OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
|
|
OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
|
|
OID is not part of the table.
|
|
[Steve Henson]
|
|
|
|
*) Add prototypes to X509 lookup/verify methods, fixing a bug in
|
|
X509_LOOKUP_by_alias().
|
|
[Ben Laurie]
|
|
|
|
*) Sort openssl functions by name.
|
|
[Ben Laurie]
|
|
|
|
*) Get the gendsa program working (hopefully) and add it to app list. Remove
|
|
encryption from sample DSA keys (in case anyone is interested the password
|
|
was "1234").
|
|
[Steve Henson]
|
|
|
|
*) Make _all_ *_free functions accept a NULL pointer.
|
|
[Frans Heymans <fheymans@isaserver.be>]
|
|
|
|
*) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
|
|
NULL pointers.
|
|
[Anonymous <nobody@replay.com>]
|
|
|
|
*) s_server should send the CAfile as acceptable CAs, not its own cert.
|
|
[Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
|
|
|
|
*) Don't blow it for numeric -newkey arguments to apps/req.
|
|
[Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
|
|
|
|
*) Temp key "for export" tests were wrong in s3_srvr.c.
|
|
[Anonymous <nobody@replay.com>]
|
|
|
|
*) Add prototype for temp key callback functions
|
|
SSL_CTX_set_tmp_{rsa,dh}_callback().
|
|
[Ben Laurie]
|
|
|
|
*) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
|
|
DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
|
|
[Steve Henson]
|
|
|
|
*) X509_name_add_entry() freed the wrong thing after an error.
|
|
[Arne Ansper <arne@ats.cyber.ee>]
|
|
|
|
*) rsa_eay.c would attempt to free a NULL context.
|
|
[Arne Ansper <arne@ats.cyber.ee>]
|
|
|
|
*) BIO_s_socket() had a broken should_retry() on Windoze.
|
|
[Arne Ansper <arne@ats.cyber.ee>]
|
|
|
|
*) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
|
|
[Arne Ansper <arne@ats.cyber.ee>]
|
|
|
|
*) Make sure the already existing X509_STORE->depth variable is initialized
|
|
in X509_STORE_new(), but document the fact that this variable is still
|
|
unused in the certificate verification process.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Fix the various library and apps files to free up pkeys obtained from
|
|
X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
|
|
[Steve Henson]
|
|
|
|
*) Fix reference counting in X509_PUBKEY_get(). This makes
|
|
demos/maurice/example2.c work, amongst others, probably.
|
|
[Steve Henson and Ben Laurie]
|
|
|
|
*) First cut of a cleanup for apps/. First the `ssleay' program is now named
|
|
`openssl' and second, the shortcut symlinks for the `openssl <command>'
|
|
are no longer created. This way we have a single and consistent command
|
|
line interface `openssl <command>', similar to `cvs <command>'.
|
|
[Ralf S. Engelschall, Paul Sutton and Ben Laurie]
|
|
|
|
*) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
|
|
BIT STRING wrapper always have zero unused bits.
|
|
[Steve Henson]
|
|
|
|
*) Add CA.pl, perl version of CA.sh, add extended key usage OID.
|
|
[Steve Henson]
|
|
|
|
*) Make the top-level INSTALL documentation easier to understand.
|
|
[Paul Sutton]
|
|
|
|
*) Makefiles updated to exit if an error occurs in a sub-directory
|
|
make (including if user presses ^C) [Paul Sutton]
|
|
|
|
*) Make Montgomery context stuff explicit in RSA data structure.
|
|
[Ben Laurie]
|
|
|
|
*) Fix build order of pem and err to allow for generated pem.h.
|
|
[Ben Laurie]
|
|
|
|
*) Fix renumbering bug in X509_NAME_delete_entry().
|
|
[Ben Laurie]
|
|
|
|
*) Enhanced the err-ins.pl script so it makes the error library number
|
|
global and can add a library name. This is needed for external ASN1 and
|
|
other error libraries.
|
|
[Steve Henson]
|
|
|
|
*) Fixed sk_insert which never worked properly.
|
|
[Steve Henson]
|
|
|
|
*) Fix ASN1 macros so they can handle indefinite length constructed
|
|
EXPLICIT tags. Some non standard certificates use these: they can now
|
|
be read in.
|
|
[Steve Henson]
|
|
|
|
*) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
|
|
into a single doc/ssleay.txt bundle. This way the information is still
|
|
preserved but no longer messes up this directory. Now it's new room for
|
|
the new set of documentation files.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) SETs were incorrectly DER encoded. This was a major pain, because they
|
|
shared code with SEQUENCEs, which aren't coded the same. This means that
|
|
almost everything to do with SETs or SEQUENCEs has either changed name or
|
|
number of arguments.
|
|
[Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
|
|
|
|
*) Fix test data to work with the above.
|
|
[Ben Laurie]
|
|
|
|
*) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
|
|
was already fixed by Eric for 0.9.1 it seems.
|
|
[Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
|
|
|
|
*) Autodetect FreeBSD3.
|
|
[Ben Laurie]
|
|
|
|
*) Fix various bugs in Configure. This affects the following platforms:
|
|
nextstep
|
|
ncr-scde
|
|
unixware-2.0
|
|
unixware-2.0-pentium
|
|
sco5-cc.
|
|
[Ben Laurie]
|
|
|
|
*) Eliminate generated files from CVS. Reorder tests to regenerate files
|
|
before they are needed.
|
|
[Ben Laurie]
|
|
|
|
*) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
|
|
[Ben Laurie]
|
|
|
|
|
|
Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
|
|
|
|
*) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
|
|
changed SSLeay to OpenSSL in version strings.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Some fixups to the top-level documents.
|
|
[Paul Sutton]
|
|
|
|
*) Fixed the nasty bug where rsaref.h was not found under compile-time
|
|
because the symlink to include/ was missing.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Incorporated the popular no-RSA/DSA-only patches
|
|
which allow to compile a RSA-free SSLeay.
|
|
[Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
|
|
|
|
*) Fixed nasty rehash problem under `make -f Makefile.ssl links'
|
|
when "ssleay" is still not found.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Added more platforms to Configure: Cray T3E, HPUX 11,
|
|
[Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
|
|
|
|
*) Updated the README file.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Added various .cvsignore files in the CVS repository subdirs
|
|
to make a "cvs update" really silent.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Recompiled the error-definition header files and added
|
|
missing symbols to the Win32 linker tables.
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Cleaned up the top-level documents;
|
|
o new files: CHANGES and LICENSE
|
|
o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
|
|
o merged COPYRIGHT into LICENSE
|
|
o removed obsolete TODO file
|
|
o renamed MICROSOFT to INSTALL.W32
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Removed dummy files from the 0.9.1b source tree:
|
|
crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
|
|
crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

|
util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
|
|
[Ralf S. Engelschall]
|
|
|
|
*) Added various platform portability fixes.
|
|
[Mark J. Cox]
|
|
|
|
*) The Genesis of the OpenSSL rpject:
|
|
We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
|
|
Young and Tim J. Hudson created while they were working for C2Net until
|
|
summer 1998.
|
|
[The OpenSSL Project]

|
*) Changed some BIGNUM api stuff.
|
|
[Eric A. Young]
|
|
|
|
*) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
|
|
DGUX x86, Linux Alpha, etc.
|
|
[Eric A. Young]
|
|
|
|
*) New COMP library [crypto/comp/] for SSL Record Layer Compression:
|
|
RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
|
|
available).
|
|
[Eric A. Young]
|
|
|
|
*) Add -strparse option to asn1pars program which parses nested
|
|
binary structures
|
|
[Dr Stephen Henson <shenson@bigfoot.com>]
|
|
|
|
*) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
|
|
[Eric A. Young]
|
|
|
|
*) DSA fix for "ca" program.
|
|
[Eric A. Young]
|
|
|
|
*) Added "-genkey" option to "dsaparam" program.
|
|
[Eric A. Young]
|
|
|
|
*) Added RIPE MD160 (rmd160) message digest.
|
|
[Eric A. Young]
|
|
|
|
*) Added -a (all) option to "ssleay version" command.
|
|
[Eric A. Young]
|
|
|
|
*) Added PLATFORM define which is the id given to Configure.
|
|
[Eric A. Young]
|
|
|
|
*) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
|
|
[Eric A. Young]
|
|
|
|
*) Extended the ASN.1 parser routines.
|
|
[Eric A. Young]
|
|
|
|
*) Extended BIO routines to support REUSEADDR, seek, tell, etc.
|
|
[Eric A. Young]
|
|
|
|
*) Added a BN_CTX to the BN library.
|
|
[Eric A. Young]
|
|
|
|
*) Fixed the weak key values in DES library
|
|
[Eric A. Young]
|
|
|
|
*) Changed API in EVP library for cipher aliases.
|
|
[Eric A. Young]
|
|
|
|
*) Added support for RC2/64bit cipher.
|
|
[Eric A. Young]
|
|
|
|
*) Converted the lhash library to the crypto/mem.c functions.
|
|
[Eric A. Young]
|
|
|
|
*) Added more recognized ASN.1 object ids.
|
|
[Eric A. Young]
|
|
|
|
*) Added more RSA padding checks for SSL/TLS.
|
|
[Eric A. Young]
|
|
|
|
*) Added BIO proxy/filter functionality.
|
|
[Eric A. Young]
|
|
|
|
*) Added extra_certs to SSL_CTX which can be used
|
|
send extra CA certificates to the client in the CA cert chain sending
|
|
process. It can be configured with SSL_CTX_add_extra_chain_cert().
|
|
[Eric A. Young]
|
|
|
|
*) Now Fortezza is denied in the authentication phase because
|
|
this is key exchange mechanism is not supported by SSLeay at all.
|
|
[Eric A. Young]
|
|
|
|
*) Additional PKCS1 checks.
|
|
[Eric A. Young]
|
|
|
|
*) Support the string "TLSv1" for all TLS v1 ciphers.
|
|
[Eric A. Young]
|
|
|
|
*) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
|
|
ex_data index of the SSL context in the X509_STORE_CTX ex_data.
|
|
[Eric A. Young]
|
|
|
|
*) Fixed a few memory leaks.
|
|
[Eric A. Young]
|
|
|
|
*) Fixed various code and comment typos.
|
|
[Eric A. Young]
|
|
|

*) A minor bug in ssl/s3_clnt.c where there would always be 4 0
|
|
bytes sent in the client random.
