- Changes between 0.9.8g and 0.9.8h [xx XXX xxxx]
+ Changes between 0.9.8i and 0.9.8j [xx XXX xxxx]
+ *)
+
+ 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_...).
+ [Nagendra Modadugu]
+
+ *) 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.
+
+ [Bodo Moeller; problem pointed out by Marius Schilder]
+
+ *) 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.
+
+ [Neel Mehta, Bodo Moeller]
+
+ *) Allow engines to be "soft loaded" - i.e. optionally don't die if
+ the load fails. Useful for distros.
+ [Ben Laurie and the FreeBSD team]
+
+ *) Add support for Local Machine Keyset attribute in PKCS#12 files.
+ [Steve Henson]
+
+ *) Fix BN_GF2m_mod_arr() top-bit cleanup code.
+ [Huang Ying]
+
+ *) Expand ENGINE to support engine supplied SSL client certificate functions.
+
+ This work was sponsored by Logica.
+ [Steve Henson]
+
+ *) 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.
+ [Steve Henson]
+
+ *) 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.
+ [Steve Henson]
+
+ Changes between 0.9.8g and 0.9.8h [28 May 2008]
+
+ *) Fix flaw if 'Server Key exchange message' is omitted from a TLS
+ handshake which could lead to a cilent crash as found using the
+ Codenomicon TLS test suite (CVE-2008-1672)
+ [Steve Henson, Mark Cox]
+
+ *) Fix double free in TLS server name extensions which could lead to
+ a remote crash found by Codenomicon TLS test suite (CVE-2008-0891)
+ [Joe Orton]
+
+ *) Clear error queue in SSL_CTX_use_certificate_chain_file()
+
+ Clear the error queue to ensure that error entries left from
+ older function calls do not interfere with the correct operation.
+ [Lutz Jaenicke, Erik de Castro Lopo]
+
+ *) Remove root CA certificates of commercial CAs:
+
+ The OpenSSL project does not recommend any specific CA and does not
+ have any policy with respect to including or excluding any CA.
+ Therefore it does not make any sense to ship an arbitrary selection
+ of root CA certificates with the OpenSSL software.
+ [Lutz Jaenicke]
+
+ *) RSA OAEP patches to fix two separate invalid memory reads.
+ The first one involves inputs when 'lzero' is greater than
+ 'SHA_DIGEST_LENGTH' (it would read about SHA_DIGEST_LENGTH bytes
+ before the beginning of from). The second one involves inputs where
+ the 'db' section contains nothing but zeroes (there is a one-byte
+ invalid read after the end of 'db').
+ [Ivan Nestlerode <inestlerode@us.ibm.com>]
+
+ *) Partial backport from 0.9.9-dev:
+
+ Introduce bn_mul_mont (dedicated Montgomery multiplication
+ procedure) as a candidate for BIGNUM assembler implementation.
+ While 0.9.9-dev uses assembler for various architectures, only
+ x86_64 is available by default here in the 0.9.8 branch, and
+ 32-bit x86 is available through a compile-time setting.
+
+ To try the 32-bit x86 assembler implementation, use Configure
+ option "enable-montasm" (which exists only for this backport).
+
+ As "enable-montasm" for 32-bit x86 disclaims code stability
+ anyway, in this constellation we activate additional code
+ backported from 0.9.9-dev for further performance improvements,
+ namely BN_from_montgomery_word. (To enable this otherwise,
+ e.g. x86_64, try "-DMONT_FROM_WORD___NON_DEFAULT_0_9_8_BUILD".)
+
+ [Andy Polyakov (backport partially by Bodo Moeller)]
+
+ *) Add TLS session ticket callback. This allows an application to set
+ TLS ticket cipher and HMAC keys rather than relying on hardcoded fixed
+ values. This is useful for key rollover for example where several key
+ sets may exist with different names.
+ [Steve Henson]
+
+ *) Reverse ENGINE-internal logic for caching default ENGINE handles.
+ This was broken until now in 0.9.8 releases, such that the only way
+ a registered ENGINE could be used (assuming it initialises
+ successfully on the host) was to explicitly set it as the default
+ for the relevant algorithms. This is in contradiction with 0.9.7
+ behaviour and the documentation. With this fix, when an ENGINE is
+ registered into a given algorithm's table of implementations, the
+ 'uptodate' flag is reset so that auto-discovery will be used next
+ time a new context for that algorithm attempts to select an
+ implementation.
+ [Ian Lister (tweaked by Geoff Thorpe)]
+
+ *) Backport of CMS code to OpenSSL 0.9.8. This differs from the 0.9.9
+ implemention in the following ways:
+
+ Lack of EVP_PKEY_ASN1_METHOD means algorithm parameters have to be
+ hard coded.
+
+ Lack of BER streaming support means one pass streaming processing is
+ only supported if data is detached: setting the streaming flag is
+ ignored for embedded content.
+
+ CMS support is disabled by default and must be explicitly enabled
+ with the enable-cms configuration option.
+ [Steve Henson]
+
+ *) Update the GMP engine glue to do direct copies between BIGNUM and
+ mpz_t when openssl and GMP use the same limb size. Otherwise the
+ existing "conversion via a text string export" trick is still used.
+ [Paul Sheer <paulsheer@gmail.com>]
+
+ *) Zlib compression BIO. This is a filter BIO which compressed and
+ uncompresses any data passed through it.
+ [Steve Henson]
+
+ *) Add AES_wrap_key() and AES_unwrap_key() functions to implement
+ RFC3394 compatible AES key wrapping.
+ [Steve Henson]
+
+ *) Add utility functions to handle ASN1 structures. ASN1_STRING_set0():
+ sets string data without copying. X509_ALGOR_set0() and
+ X509_ALGOR_get0(): set and retrieve X509_ALGOR (AlgorithmIdentifier)
+ data. Attribute function X509at_get0_data_by_OBJ(): retrieves data
+ from an X509_ATTRIBUTE structure optionally checking it occurs only
+ once. ASN1_TYPE_set1(): set and ASN1_TYPE structure copying supplied
+ data.
+ [Steve Henson]
+
+ *) Fix BN flag handling in RSA_eay_mod_exp() and BN_MONT_CTX_set()
+ to get the expected BN_FLG_CONSTTIME behavior.
+ [Bodo Moeller (Google)]
+
*) Netware support:
- fixed wrong usage of ioctlsocket() when build for LIBC BSD sockets
authentication-only ciphersuites.
[Bodo Moeller]
+ *) Update the SSL_get_shared_ciphers() fix CVE-2006-3738 which was
+ not complete and could lead to a possible single byte overflow
+ (CVE-2007-5135) [Ben Laurie]
