+commit 208d54db20d58c9a5e45e856a0650caadd7d9612
+Author: Dr. Stephen Henson <steve@openssl.org>
+Date: Tue May 13 18:48:31 2014 +0100
+
+ Fix for CVE-2014-0195
+
+ A buffer overrun attack can be triggered by sending invalid DTLS fragments
+ to an OpenSSL DTLS client or server. This is potentially exploitable to
+ run arbitrary code on a vulnerable client or server.
+
+ Fixed by adding consistency check for DTLS fragments.
+
+ Thanks to Jüri Aedla for reporting this issue.
+
+Patch borrowed from Fedora
