Security Advisory - openssl - CVE-2013-6449
The ssl_get_algorithm2 function in ssl/s3_lib.c in OpenSSL before 1.0.2 obtains a certain version number from an incorrect data structure, which allows remote attackers to cause a denial of service (daemon crash) via crafted traffic from a TLS 1.2 client.

4Subject: [PATCH] Use version in SSL_METHOD not SSL structure.

6Upstream-Status: Backport
7commit ca989269a2876bae79393bd54c3e72d49975fc75 upstream
8
9When deciding whether to use TLS 1.2 PRF and record hash algorithms
10use the version number in the corresponding SSL_METHOD structure
11instead of the SSL structure. The SSL structure version is sometimes
12inaccurate. Note: OpenSSL 1.0.2 and later effectively do this already.
