OpenSSL CHANGES
_______________
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.

Security fix for CVS-2012-2131.
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)

NEWS
====
This file gives a brief overview of the major changes between each OpenSSL
release. For more details please read the CHANGES file.
Major changes between OpenSSL 0.9.8u and OpenSSL 0.9.8v:
o Fix for ASN1 overflow bug CVE-2012-2110
|

'should be ok' joerg@
|
|
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.

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)

OpenSSL CHANGES
_______________
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. (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 Käóper (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 Käóper (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

OpenSSL CHANGES
_______________
Changes between 0.9.8n and 0.9.8o [01 Jun 2010]
*) 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

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).

The OpenSSL project team is pleased to announce the release of
version 0.9.8m of our open source toolkit for SSL/TLS. This new
OpenSSL version is a security and bugfix release which implements
RFC5746 to address renegotiation vulnerabilities mentioned in
CVE-2009-3555. For a complete list of changes,
please see http://www.openssl.org/source/exp/CHANGES.

Approved by agc@.
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.

* Not only interix-3, but also treat all interix release, allow to build on SUA.
* Gave up randomized image base, use 0x5e000000, as in mk/platform/Interix.mk.
It is workaround of PR 42369.
* Use -D_REENTRANT flags for threads.
* replace -Wl,soname= linker flags with -Wl,h, for Interix

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)
*) 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)
*) 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)
*) Set S/MIME signing as the default purpose rather than setting it
unconditionally. This allows applications to override it at the store
level.
*) Permit restricted recursion of ASN1 strings. This is needed in practice
to handle some structures.
*) Improve efficiency of mem_gets: don't search whole buffer each time
for a '\n'
*) New -hex option for openssl rand.
*) Print out UTF8String and NumericString when parsing ASN1.
*) Support NumericString type for name components.
*) Allow CC in the environment to override the automatically chosen
compiler. Note that nothing is done to ensure flags work with the
chosen compiler.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Changes between 0.9.8i and 0.9.8j [07 Jan 2009]
*) Properly check EVP_VerifyFinal() and similar return values
(CVE-2008-5077).
*) 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.)
*) Use correct exit code if there is an error in dgst command.
*) Tweak Configure so that you need to say "experimental-jpake" to enable
JPAKE, and need to use -DOPENSSL_EXPERIMENTAL_JPAKE in applications.
*) Add experimental JPAKE support, including demo authentication in
s_client and s_server.
*) Set the comparison function in v3_addr_canonize().
*) Add support for XMPP STARTTLS in s_client.
*) 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.)
Changes between 0.9.8h and 0.9.8i [15 Sep 2008]
*) Fix a state transitition in s3_srvr.c and d1_srvr.c
(was using SSL3_ST_CW_CLNT_HELLO_B, should be ..._ST_SW_SRVR_...).
*) 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.
*) 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.
*) Add support for Local Machine Keyset attribute in PKCS#12 files.
*) Fix BN_GF2m_mod_arr() top-bit cleanup code.
*) Expand ENGINE to support engine supplied SSL client certificate functions.
This work was sponsored by Logica.
*) Add CryptoAPI ENGINE to support use of RSA and DSA keys held in Windows
keystores. Support for SSL/TLS client authentication too.
Not compiled unless enable-capieng specified to Configure.
This work was sponsored by Logica.
*) Fix bug in X509_ATTRIBUTE creation: dont set attribute using
ASN1_TYPE_set1 if MBSTRING flag set. This bug would crash certain
attribute creation routines such as certifcate requests and PKCS#12
files.
