OpenSSL CHANGES
_______________
+ 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)]

*) Change 'Configure' script to enable Camellia by default.

for multi-threaded use of ECDH.
