Date:	10/28/2013
Bugs:	#455560, #471788
ID:	201310-18

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.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-libs/gnutls	< 2.12.23-r1	>= 2.12.23-r1	All supported architectures

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"
