CVEs (cve.mitre.org):	CVE-2009-2730

Details

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.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
