  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.

- * This is my modest contributon to the OpenSSL project (see
- * http://www.openssl.org/ for more information about it) and is
- * a drop-in MIPS III/IV ISA replacement for crypto/bn/bn_asm.c
- * module. For updates see http://fy.chalmers.se/~appro/hpe/.
- *
- * The module is designed to work with either of the "new" MIPS ABI(5),
- * namely N32 or N64, offered by IRIX 6.x. It's not ment to work under
- * IRIX 5.x not only because it doesn't support new ABIs but also
- * because 5.x kernels put R4x00 CPU into 32-bit mode and all those
- * 64-bit instructions (daddu, dmultu, etc.) found below gonna only
- * cause illegal instruction exception:-(
- *
- * In addition the code depends on preprocessor flags set up by MIPSpro
- * compiler driver (either as or cc) and therefore (probably?) can't be
- * compiled by the GNU assembler. GNU C driver manages fine though...
- * I mean as long as -mmips-as is specified or is the default option,
- * because then it simply invokes /usr/bin/as which in turn takes
- * perfect care of the preprocessor definitions. Another neat feature
- * offered by the MIPSpro assembler is an optimization pass. This gave
- * me the opportunity to have the code looking more regular as all those
- * architecture dependent instruction rescheduling details were left to
- * the assembler. Cool, huh?
- *
- * Performance improvement is astonishing! 'apps/openssl speed rsa dsa'
- * goes way over 3 times faster!

+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

 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
