RHEL 6 : gnutls (RHSA-2014:0595)

Synopsis :

The remote Red Hat 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.
