Announcement ID: SUSE-SU-2014:0322-1
Rating: critical
References: #760265 #802651 #821818 #835760 #865804 #865993

Cross-References: CVE-2009-5138 CVE-2013-1619 CVE-2013-2116
Affected Products:
SUSE Linux Enterprise Server 11 SP1 LTSS

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


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
* memory leak in PSK authentication (bnc#835760)
