RHSA-2005:004 - lesstif security update

Synopsis

lesstif security update

Type/Severity

Security Advisory Moderate

Topic

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

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.
