SUSE Security Update: Security update for gnutls
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)
