openssl: fix CVE-2014-0195
From the OpenSSL Security Advisory [05 Jun 2014]
http://www.openssl.org/news/secadv_20140605.txt
DTLS invalid fragment vulnerability (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.
Only applications using OpenSSL as a DTLS client or server affected.
(Patch borrowed from Fedora.)
