OpenSSL CHANGES
_______________
Changes between 0.9.8m (?) and 1.0.0 [xx XXX xxxx]
Changes between 0.9.8n and 1.0.0 [xx XXX xxxx]
*) Add "missing" function EVP_CIPHER_CTX_copy(). This copies a cipher
context. The operation can be customised via the ctrl mechanism in
@ -15,7 +15,7 @@
*) Add new -subject_hash_old and -issuer_hash_old options to x509 utility to
output hashes compatible with older versions of OpenSSL.
[Willy Weisz <weisz@vcpc.univie.ac.at>]
*) Fix compression algorithm handling: if resuming a session use the
compression algorithm of the resumed session instead of determining
it from client hello again. Don't allow server to change algorithm.

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

Changes between 0.9.8m and 0.9.8n [xx XXX xxxx]
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-####)
[Bodo Moeller, Adam Langley]
*) 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).
[Tomas Hoger <thoger@redhat.com>]
Changes between 0.9.8l and 0.9.8m [25 Feb 2010]
Changes between 0.9.8l and 0.9.8m [25 Feb 2010]
*) Always check bn_wexpend() return values for failure. (CVE-2009-3245)
[Martin Olsson, Neel Mehta]
*) Fix X509_STORE locking: Every 'objs' access requires a lock (to
accommodate for stack sorting, always a write lock!).
