OpenSSL CHANGES
_______________
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.
Reencode 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.
(CVE-2014-3570)
[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.
[Emilia Käsper]
Changes between 1.0.1i and 1.0.1j [15 Oct 2014]
*) SRTP Memory Leak.

1. Introduction
Proxy certificates are defined in RFC 3820. They are really usual
certificates with the mandatory extension proxyCertInfo.
Proxy certificates are defined in RFC 3820. They are really usual certificates
with the mandatory extension proxyCertInfo.
Proxy certificates are issued by an End Entity (typically a user),
either directly with the EE certificate as issuing certificate, or by
extension through an already issued proxy certificate.. They are used
to extend rights to some other entity (a computer process, typically,
or sometimes to the user itself), so it can perform operations in the
name of the owner of the EE certificate.
Proxy certificates are issued by an End Entity (typically a user), either
directly with the EE certificate as issuing certificate, or by extension through
an already issued proxy certificate. Proxy certificates are used to extend
rights to some other entity (a computer process, typically, or sometimes to the
user itself). This allows the entity to perform operations on behalf of the
owner of the EE certificate.
See http://www.ietf.org/rfc/rfc3820.txt for more information.
2. A warning about proxy certificates
Noone seems to have tested proxy certificates with security in mind.
Basically, to this date, it seems that proxy certificates have only
been used in a world that's highly aware of them. What would happen
if an unsuspecting application is to validate a chain of certificates
that contains proxy certificates? It would usually consider the leaf
to be the certificate to check for authorisation data, and since proxy
certificates are controlled by the EE certificate owner alone, it's
would be normal to consider what the EE certificate owner could do
with them.
No one seems to have tested proxy certificates with security in mind. To this
date, it seems that proxy certificates have only been used in a context highly
aware of them.
subjectAltName and issuerAltName are forbidden in proxy certificates,
and this is enforced in OpenSSL. The subject must be the same as the
issuer, with one commonName added on.
Existing applications might misbehave when trying to validate a chain of
certificates which use a proxy certificate. They might incorrectly consider the
leaf to be the certificate to check for authorisation data, which is controlled
by the EE certificate owner.
Possible threats are, as far as has been imagined so far:
subjectAltName and issuerAltName are forbidden in proxy certificates, and this
is enforced in OpenSSL. The subject must be the same as the issuer, with one
commonName added on.
Possible threats we can think of at this time include:
- impersonation through commonName (think server certificates).
- use of additional extensions, possibly non-standard ones used in
certain environments, that would grant extra or different
authorisation rights.
- use of additional extensions, possibly non-standard ones used in certain
environments, that would grant extra or different authorisation rights.
For this reason, OpenSSL requires that the use of proxy certificates
be explicitely allowed. Currently, this can be done using the
following methods:
For these reasons, OpenSSL requires that the use of proxy certificates be
explicitly allowed. Currently, this can be done using the following methods:
- if the application calls X509_verify_cert() itself, it can do the
following prior to that call (ctx is the pointer passed in the call
to X509_verify_cert()):
- if the application directly calls X509_verify_cert(), it can first call:
X509_STORE_CTX_set_flags(ctx, X509_V_FLAG_ALLOW_PROXY_CERTS);
X509_STORE_CTX_set_flags(ctx, X509_V_FLAG_ALLOW_PROXY_CERTS);
- in all other cases, proxy certificate validation can be enabled
before starting the application by setting the envirnoment variable
OPENSSL_ALLOW_PROXY_CERTS with some non-empty value.
Where ctx is the pointer which then gets passed to X509_verify_cert().
There are thoughts to allow proxy certificates with a line in the
default openssl.cnf, but that's still in the future.
- proxy certificate validation can be enabled before starting the application
by setting the environment variable OPENSSL_ALLOW_PROXY_CERTS.
In the future, it might be possible to enable proxy certificates by editing
openssl.cnf.

4. How to have your application interpret the policy?
The basic way to interpret proxy policies is to prepare some default
rights, then do a check of the proxy certificate against the a chain
of proxy certificates, user certificate and CA certificates, and see
what rights came out by the end. Sounds easy, huh? It almost is.

The slightly complicated part is figuring out how to pass data between your
application and the certificate validation procedure.
You need the following ingredients:
- a callback routing that will be called for every certificate that's
validated. It will be called several times for each certificates,
so you must be attentive to when it's a good time to do the proxy
policy interpretation and check, as well as to fill in the defaults
when the EE certificate is checked.
- a callback function that will be called for every certificate being
validated. The callback be called several times for each certificate,
so you must be careful to do the proxy policy interpretation at the right
time. You also need to fill in the defaults when the EE certificate is
checked.
- a structure of data that's shared between your application code and
the callback.
- a data structure that is shared between your application code and the
callback.
- a wrapper function that sets it all up.
- an ex_data index function that creates an index into the generic
ex_data store that's attached to an X509 validation context.

RSA keys are always used. This option breaks compatibility with the

An application may either directly specify the key or can supply the key via
a callback function. The callback approach has the advantage, that the
callback may generate the key only in case it is actually needed. As the
generation of a RSA key is however costly, it will lead to a significant
delay in the handshake procedure. Another advantage of the callback function
is that it can supply keys of different size (e.g. for SSL_OP_EPHEMERAL_RSA
usage) while the explicit setting of the key is only useful for key size of
512 bits to satisfy the export restricted ciphers and does give away key length
if a longer key would be allowed.
