RHEL 4 / 5 : gnutls (RHSA-2009:1232)

High Nessus Plugin ID 40782


The remote Red Hat host is missing one or more security updates.


Updated gnutls packages that fix a security issue are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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

A flaw was discovered in the way GnuTLS handles NULL characters in certain fields of X.509 certificates. If an attacker is able to get a carefully-crafted certificate signed by a Certificate Authority trusted by an application using GnuTLS, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse the application into accepting it by mistake. (CVE-2009-2730)

Users of GnuTLS are advised to upgrade to these updated packages, which contain a backported patch that corrects this issue.


Update the affected gnutls, gnutls-devel and / or gnutls-utils packages.
