197e0ea Fix for TLS record tampering bug. (CVE-2013-4353).
3462896 For DTLS we might need to retransmit messages from the
previous session so keep a copy of write context in DTLS
retransmission buffers instead of replacing it after
sending CCS. (CVE-2013-6450).
ca98926 When deciding whether to use TLS 1.2 PRF and record hash
algorithms use the version number in the corresponding
SSL_METHOD structure instead of the SSL structure. The
SSL structure version is sometimes inaccurate.
Note: OpenSSL 1.0.2 and later effectively do this already.
(CVE-2013-6449).

This also "reverts" some FreeBSD local changes so we should now
be back to using entirely stock OpenSSL. The local changes were
simple $FreeBSD$ lines additions, which were required in the CVS
days, and the patch for FreeBSD-SA-09:15.ssl which has been
superseded with OpenSSL 0.9.8m's RFC5746 'TLS renegotiation
extension' support.

- Fix memory consumption bug with "future epoch" DTLS records.
- Fix fragment handling memory leak.
- Do not access freed data structure.
- Fix DTLS fragment bug - out-of-sequence message handling which could
result in NULL pointer dereference in
dtls1_process_out_of_seq_message().
Note that this will not get FreeBSD Security Advisory as DTLS is
experimental in OpenSSL.

From the OpenSSL advisory:
Andy Polyakov discovered a flaw in OpenSSL's DTLS
implementation which could lead to the compromise of clients
and servers with DTLS enabled.
DTLS is a datagram variant of TLS specified in RFC 4347 first
supported in OpenSSL version 0.9.8. Note that the
vulnerabilities do not affect SSL and TLS so only clients and
servers explicitly using DTLS are affected.
We believe this flaw will permit remote code execution.
