   An update that solves 9 vulnerabilities and has one errata
   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: The TLS implementation in GnuTLS did
   not properly consider timing side-channel attacks on a
   noncompliant MAC check operation during the processing of
   malformed CBC padding, which allows remote attackers to
   conduct distinguishing attacks and plaintext-recovery
   attacks via statistical analysis of timing data for crafted
   packets, a related issue to CVE-2013-0169. (Lucky13)
   * CVE-2012-1569: The asn1_get_length_der function in
   decoding.c in GNU Libtasn1 , as used in GnuTLS did not
   properly handle certain large length values, which allowed
   remote attackers to cause a denial of service (heap memory
   corruption and application crash) or possibly have
   unspecified other impact via a crafted ASN.1 structure.
   * CVE-2012-1573: gnutls_cipher.c in libgnutls in GnuTLS
   did not properly handle data encrypted with a block cipher,
   which allowed remote attackers to cause a denial of service
   (heap memory corruption and application crash) via a
   crafted record, as demonstrated by a crafted
   GenericBlockCipher structure.
   * CVE-2012-0390: The DTLS implementation in GnuTLS
   executed certain error-handling code only if there is a
   specific relationship between a padding length and the
   ciphertext size, which made it easier for remote attackers
   to recover partial plaintext via a timing side-channel
   attack, a related issue to CVE-2011-4108.

   Also some non security bugs have been fixed:

   * Did some more s390x size_t vs int fixes. (bnc#536809,
   bnc#659128)
   * re-enabled "legacy negotiation" (bnc#554084)
   * fix safe-renegotiation for sle10sp3 and sle10sp4 bug
   (bnc#554084)
   * fix bug bnc#536809, fix gnutls-cli to abort
   connection after detecting a bad certificate
