   An update that solves four vulnerabilities and has two
   fixes is now available.

Description:


   The GnuTLS library received a critical security fix and
   other updates:

   * CVE-2014-0092: The X.509 certificate verification had
   incorrect error handling, which could lead to broken
   certificates marked as being valid.
   * CVE-2009-5138: A verification problem in handling V1
   certificates could also lead to V1 certificates incorrectly
   being handled.
   * CVE-2013-2116: The _gnutls_ciphertext2compressed
   function in lib/gnutls_cipher.c in GnuTLS allowed remote
   attackers to cause a denial of service (buffer over-read
   and crash) via a crafted padding length.
   * CVE-2013-1619: Timing attacks against hashing of
   padding was fixed which might have allowed disclosure of
   keys. (Lucky13 attack).

   Also the following non-security bugs have been fixed:

   * gnutls doesn't like root CAs without Basic
   Constraints. Permit V1 Certificate Authorities properly
   (bnc#760265)
   * memory leak in PSK authentication (bnc#835760)
