openssl: fix CVE-2014-0198
A null pointer dereference bug was discovered in do_ssl3_write(). An attacker could possibly use this to cause OpenSSL to crash, resulting in a denial of service. https://access.redhat.com/security/cve/CVE-2014-0198 (From OE-Core rev: 580033721abbbb4302bc803ebc70c90e331e4587) (From OE-Core rev: c3f6cea0b8f1de1e2042087c26ebe42ff909c1ed) Signed-off-by: Maxin B.
