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).

Check DTLS_BAD_VER for version number.
The version check for DTLS1_VERSION was redundant as
DTLS1_VERSION > TLS1_1_VERSION, however we do need to
check for DTLS1_BAD_VER for compatibility.

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.

Do not access freed data structure.

FIPS works but at least now we have the support source in case it
does.
- Do not exclude rsaref - it's not part of the OpenSSL distribution
archive anymore.
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.

EVP_CIPHER_CTX_key_length() should return the set key length
in the EVP_CIPHER_CTX structure which may not be the same as
the underlying cipher key length for variable length ciphers.
This fixes problems in OpenSSH using some ciphers, and possibly other
applications.

Fix uninitialized free of ctx in compute_key() when the
OPENSSL_DH_MAX_MODULUS_BITS check is triggered.
This fixes the same issue as FreeBSD-SA-06:23.openssl v1.1.
