Detail

Synopsis

Multiple vulnerabilities have been discovered in GnuTLS, the worst of which could lead to Denial of Service.

Background

GnuTLS is an Open Source implementation of the TLS 1.2 and SSL 3.0
protocols.

Description

Multiple vulnerabilities have been discovered in GnuTLS. Please review the CVE identifiers and Lucky Thirteen research paper referenced below for details.

Impact

A remote attacker could sent a specially crafted packet to cause a Denial of Service condition. Additionally, a remote attacker could perform man-in-the-middle attacks to recover plaintext data.

Workaround

There is no known workaround at this time.

Resolution

All GnuTLS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/gnutls-2.12.23-r1"

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: 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)
