CentOS 6 : gnutls (CESA-2014:0595)

medium Nessus Plugin ID 74310

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated gnutls packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

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).

A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. A malicious server could use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS, causing the client application to crash or, possibly, execute arbitrary code. (CVE-2014-3466)

Red Hat would like to thank GnuTLS upstream for reporting this issue.
Upstream acknowledges Joonas Kuorilehto of Codenomicon as the original reporter.

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 gnutls packages.
