Detail

Problem Description:

An updated gdm package that fixes a security issue is now available for Red Hat Enterprise Linux 5.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Problem description:

Gdm (the GNOME Display Manager) is a highly configurable reimplementation of xdm, the X Display Manager. Gdm allows you to log into your system with the X Window System running and supports running several different X sessions on your local machine at the same time.

A flaw was found in the way Gdm listens on its unix domain socket. A local user could crash a running X session by writing malicious data to Gdm's unix domain socket. (CVE-2007-3381)

All users of gdm should upgrade to this updated package, which contains a backported patch that resolves this issue.

Red Hat would like to thank JLANTHEA for reporting this issue.

4. 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 http://kbase.redhat.com/faq/FAQ_58_10188
