"OpenSSL has been updated to fix an attack on ECDSA Nonces.

Using the FLUSH+RELOAD Cache Side-channel Attack the Nonces could be
recovered. (CVE-2014-0076)

The update also enables use of SHA-2 family certificate verification
of X.509 certificates used in todays SSL certificate infrastructure.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
