*) Change 'Configure' script to enable Camellia by default.
[NTT]
- Changes between 0.9.8x and 0.9.8y [5 Feb 2013]
-
- *) Make the decoding of SSLv3, TLS and DTLS CBC records constant time.
-
- This addresses the flaw in CBC record processing discovered by
- Nadhem Alfardan and Kenny Paterson. Details of this attack can be found
- at: http://www.isg.rhul.ac.uk/tls/
-
- 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 Adam Langley and
- Emilia Käsper for the initial patch.
- (CVE-2013-0169)
- [Emilia Käsper, Adam Langley, Ben Laurie, Andy Polyakov, Steve Henson]
-
- *) Return an error when checking OCSP signatures when key is NULL.
- This fixes a DoS attack. (CVE-2013-0166)
- [Steve Henson]
-
- *) 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.
- See http://rt.openssl.org/Ticket/Display.html?id=2836.
- (This is a backport)
- [Rob Stradling <rob.stradling@comodo.com>]
-
- *) Fix possible deadlock when decoding public keys.
- [Steve Henson]
-
- Changes between 0.9.8w and 0.9.8x [10 May 2012]
-
- *) Sanity check record length before skipping explicit IV in DTLS
- to fix DoS attack.
-
- Thanks to Codenomicon for discovering this issue using Fuzz-o-Matic
- fuzzing as a service testing platform.
- (CVE-2012-2333)
- [Steve Henson]
-
- *) Initialise tkeylen properly when encrypting CMS messages.
- Thanks to Solar Designer of Openwall for reporting this issue.
- [Steve Henson]
-
- Changes between 0.9.8v and 0.9.8w [23 Apr 2012]
-
- *) The fix for CVE-2012-2110 did not take into account that the
- 'len' argument to BUF_MEM_grow and BUF_MEM_grow_clean is an
- int in OpenSSL 0.9.8, making it still vulnerable. Fix by
- rejecting negative len parameter. (CVE-2012-2131)
- [Tomas Hoger <thoger@redhat.com>]
-
- Changes between 0.9.8u and 0.9.8v [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.
-
- Thanks to Tavis Ormandy, Google Security Team, for discovering this
- issue and to Adam Langley <agl@chromium.org> for fixing it.
- (CVE-2012-2110)
- [Adam Langley (Google), Tavis Ormandy, Google Security Team]
-
- Changes between 0.9.8t and 0.9.8u [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 reenabled 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.
- [Steve Henson]
-
- Changes between 0.9.8s and 0.9.8t [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 0.9.8r and 0.9.8s [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]
-
- *) Stop policy check failure freeing same buffer twice. (CVE-2011-4109)
- [Ben Laurie, Kasper <ekasper@google.com>]
-
- *) 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)]
-
- *) 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>]
-
- *) 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)]
-
- *) Fix SSL memory handling for (EC)DH ciphersuites, in particular
- for multi-threaded use of ECDH.
- [Adam Langley (Google)]
-
- *) Fix x509_name_ex_d2i memory leak on bad inputs.
- [Bodo Moeller]
-
- *) 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
-
- [Billy Bob Brumley and Nicola Tuveri]
-
- Changes between 0.9.8q and 0.9.8r [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 0.9.8p and 0.9.8q [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 0.9.8o and 0.9.8p [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 for double free bug in ssl/s3_clnt.c CVE-2010-2939
- [Steve Henson]
-
- *) Don't reencode certificate when calculating signature: cache and use
- the original encoding instead. This makes signature verification of
- some broken encodings work correctly.
- [Steve Henson]
-
- *) ec2_GF2m_simple_mul bugfix: compute correct result if the output EC_POINT
- is also one of the inputs.
- [Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
-
- *) Don't repeatedly append PBE algorithms to table if they already exist.
- Sort table on each new add. This effectively makes the table read only
- after all algorithms are added and subsequent calls to PKCS12_pbe_add
- etc are non-op.
- [Steve Henson]
-
- Changes between 0.9.8n and 0.9.8o [01 Jun 2010]
-
- [NB: OpenSSL 0.9.8o and later 0.9.8 patch levels were released after
- OpenSSL 1.0.0.]
-
- *) Correct a typo in the CMS ASN1 module which can result in invalid memory
- access or freeing data twice (CVE-2010-0742)
- [Steve Henson, Ronald Moesbergen <intercommit@gmail.com>]
-
- *) Add SHA2 algorithms to SSL_library_init(). SHA2 is becoming far more
- common in certificates and some applications which only call
- SSL_library_init and not OpenSSL_add_all_algorithms() will fail.
- [Steve Henson]
-
- *) VMS fixes:
- Reduce copying into .apps and .test in makevms.com
- Don't try to use blank CA certificate in CA.com
- Allow use of C files from original directories in maketests.com
- [Steven M. Schweda" <sms@antinode.info>]
