Description

Updated gnutls packages that fix one security issue are now available for Red Hat Enterprise Linux 4 Extended Life Cycle Support, Red Hat Enterprise Linux 5.3, 5.6 and 6.2 Long Life, and Red Hat Enterprise Linux 5.9, 6.3 and 6.4 Extended Update Support.

The Red Hat Security Response Team has rated this update as having Important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS).

It was discovered that GnuTLS did not correctly handle certain errors that could occur during the verification of an X.509 certificate, causing it to incorrectly report a successful verification. An attacker could use this flaw to create a specially crafted certificate that could be accepted by GnuTLS as valid for a site chosen by the attacker. (CVE-2014-0092)

This issue was discovered by Nikos Mavrogiannopoulos of the Red Hat Security Technologies Team.

Users of GnuTLS are advised to upgrade to these updated packages, which correct this issue. For the update to take effect, all applications linked to the GnuTLS library must be restarted.

Solution

Update the affected packages.
