----------------------------------------------------------------------

1. Summary:

An updated lesstif package that fixes flaws in the Xpm library is now available for Red Hat Enterprise Linux 2.1.



2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

LessTif provides libraries which implement the Motif industry standard graphical user interface.

During a source code audit, Chris Evans discovered several stack overflow flaws and an integer overflow flaw in the libXpm library used to decode XPM (X PixMap) images. A vulnerable version of this library was found within Lesstif. 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 CAN-2004-0687,CAN-2004-0688, and CAN-2004-0914 to these issues.

Users of LessTif are advised to upgrade to this erratum package, which contains backported security patches to the embedded libXpm library.
