RHEL 3 : XFree86 (RHSA-2004:478)

This script is Copyright (C) 2004-2016 Tenable Network Security, Inc.

Synopsis :

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

Description :

Updated XFree86 packages that fix several security flaws in libXpm, as
well as other bugs, are now available for Red Hat Enterprise Linux 3.

XFree86 is an open source implementation of the X Window System. It
provides the basic low level functionality which full fledged
graphical user interfaces (GUIs) such as GNOME and KDE are designed

During a source code audit, Chris Evans discovered several stack
overflow flaws and an integer overflow flaw in the X.Org libXpm
library used to decode XPM (X PixMap) images. An attacker could create
a carefully crafted XPM file which would cause an application to crash
or potentially execute arbitrary code if opened by a victim. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the names CVE-2004-0687, CVE-2004-0688, and CVE-2004-0692 to
these issues.

A flaw was found in the X Display Manager (XDM). XDM is shipped with
Red Hat Enterprise Linux, but is not used by default. XDM opened a
chooserFd TCP socket even if the DisplayManager.requestPort parameter
was set to 0. This allowed authorized users to access a machine
remotely via X, even if the administrator had configured XDM to refuse
such connections. Although XFree86 4.3.0 was not vulnerable to this
issue, Red Hat Enterprise Linux 3 contained a backported patch which
introduced this flaw. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0419 to this issue.

Users are advised to upgrade to these erratum packages, which contain
backported security patches to correct these and a number of other
