Security update for gnutls (critical)

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)
