OpenSSL CHANGES
_______________
- Changes between 0.9.8i and 0.9.9 [xx XXX xxxx]
+ Changes between 0.9.8j and 0.9.9 [xx XXX xxxx]
+
+ *) Enhance the hash format used for certificate directory links. The new
+ form uses the canonical encoding (meaning equivalent names will work
+ even if they aren't identical) and uses SHA1 instead of MD5. This form
+ is incompatible with the older format and as a result c_rehash should
+ be used to rebuild symbolic links.
+ [Steve Henson]
+
+ *) Make PKCS#8 the default write format for private keys, replacing the
+ traditional format. This form is standardised, more secure and doesn't
+ include an implicit MD5 dependency.
+ [Steve Henson]
+
+ *) Add a $gcc_devteam_warn option to Configure. The idea is that any code
+ committed to OpenSSL should pass this lot as a minimum.
+ [Steve Henson]
+
+ *) Add session ticket override functionality for use by EAP-FAST.
+ [Jouni Malinen <j@w1.fi>]
+
+ *) Modify HMAC functions to return a value. Since these can be implemented
+ in an ENGINE errors can occur.
+ [Steve Henson]
+
+ *) Type-checked OBJ_bsearch_ex.
+ [Ben Laurie]
+
+ *) Type-checked OBJ_bsearch. Also some constification necessitated
+ by type-checking. Still to come: TXT_DB, bsearch(?),
+ OBJ_bsearch_ex, qsort, CRYPTO_EX_DATA, ASN1_VALUE, ASN1_STRING,
+ CONF_VALUE.
+ [Ben Laurie]
+
+ *) New function OPENSSL_gmtime_adj() to add a specific number of days and
+ seconds to a tm structure directly, instead of going through OS
+ specific date routines. This avoids any issues with OS routines such
+ as the year 2038 bug. New *_adj() functions for ASN1 time structures
+ and X509_time_adj_ex() to cover the extended range. The existing
+ X509_time_adj() is still usable and will no longer have any date issues.
+ [Steve Henson]
+
+ *) Delta CRL support. New use deltas option which will attempt to locate
+ and search any appropriate delta CRLs available.
+
+ This work was sponsored by Google.
+ [Steve Henson]
+
+ *) Support for CRLs partitioned by reason code. Reorganise CRL processing
+ code and add additional score elements. Validate alternate CRL paths
+ as part of the CRL checking and indicate a new error "CRL path validation
+ error" in this case. Applications wanting additional details can use
+ the verify callback and check the new "parent" field. If this is not
+ NULL CRL path validation is taking place. Existing applications wont
+ see this because it requires extended CRL support which is off by
+ default.
+
+ This work was sponsored by Google.
+ [Steve Henson]
*) Support for freshest CRL extension.
*) Initial indirect CRL support. Currently only supported in the CRLs
passed directly and not via lookup. Process certificate issuer
CRL entry extension and lookup CRL entries by bother issuer name
- and serial number. Check and proces CRL issuer entry in IDP extension.
+ and serial number. Check and process CRL issuer entry in IDP extension.

[Steve Henson]
*) Change 'Configure' script to enable Camellia by default.
[NTT]
- Changes between 0.9.8h and 0.9.8i [xx XXX xxxx]
+ Changes between 0.9.8j and 0.9.8k [xx XXX xxxx]
+
+ *) Allow CC in the environment to override the automatically chosen
+ compiler. Note that nothing is done to ensure flags work with the
+ chosen compiler.
+ [Ben Laurie]
+
+ Changes between 0.9.8i and 0.9.8j [07 Jan 2009]
+
+ *) Properly check EVP_VerifyFinal() and similar return values
+ (CVE-2008-5077).
+ [Ben Laurie, Bodo Moeller, Google Security Team]
+
+ *) Enable TLS extensions by default.
+ [Ben Laurie]
+
+ *) 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.)
+ [Sander Temme <sander@temme.net>]
+
+ *) Use correct exit code if there is an error in dgst command.
+ [Steve Henson; problem pointed out by Roland Dirlewanger]
+
+ *) Tweak Configure so that you need to say "experimental-jpake" to enable
+ JPAKE, and need to use -DOPENSSL_EXPERIMENTAL_JPAKE in applications.
+ [Bodo Moeller]
+
+ *) Add experimental JPAKE support, including demo authentication in
+ s_client and s_server.
+ [Ben Laurie]
+
+ *) Set the comparison function in v3_addr_canonize().
+ [Rob Austein <sra@hactrn.net>]
+
+ *) Add support for XMPP STARTTLS in s_client.
+ [Philip Paeps <philip@freebsd.org>]
+
+ *) 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.)
+ [Bodo Moeller]
+
+ 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]
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
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
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>, Geoff Thorpe]
+ [Paul Sheer <paulsheer@gmail.com>]
*) Zlib compression BIO. This is a filter BIO which compressed and
uncompresses any data passed through it.
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]
+
Changes between 0.9.8d and 0.9.8e [23 Feb 2007]
*) Since AES128 and AES256 (and similarly Camellia128 and
BN_mod_exp_mont_consttime() is the new exponentiation implementation,
