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.) (From OE-Core rev: 5bcb997663a6bd7a4d7395dcdb5e027d7f2bab81) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
