Rating: critical
References: #760265 #802651 #821818 #835760 #865804 #865993
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)
