+Subject: [PATCH] Fix DTLS retransmission from previous session.
+
+Upstream-Status: Backport
+commit 34628967f1e65dc8f34e000f0f5518e21afbfc7b upstream
+
+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.

+Subject: [PATCH] Use version in SSL_METHOD not SSL structure.
+
+Upstream-Status: Backport
+commit ca989269a2876bae79393bd54c3e72d49975fc75 upstream
+
+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.

+Subject: [PATCH] Add heartbeat extension bounds check.
+
+A missing bounds check in the handling of the TLS heartbeat extension
+can be used to reveal up to 64k of memory to a connected client or
+server.
+
+Thanks for Neel Mehta of Google Security for discovering this bug and to
+Adam Langley <[email protected]> and Bodo Moeller <[email protected]> for
+preparing the fix (CVE-2014-0160)
+
+Patch (tweaked version of upstream fix without CHANGES change) borrowed
+from Debian.
