| Description: | Summary:
The remote host is missing an update for the 'gnutls' package(s) announced via the SUSE-SU-2014:0320-1 advisory.
Vulnerability Insight:
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
