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
