+Subject: Add heartbeat extension bounds check.
+X-Git-Tag: OpenSSL_1_0_1g~3
+X-Git-Url: http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=96db902
+
+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 <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for
+preparing the fix (CVE-2014-0160)
