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: net-libs/gnutls
Vulnerable: < 2.12.23-r1
Unaffected: >= 2.12.23-r1
Architectures: 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:
Code:
# emerge --sync
