(RHSA-2005:004) lesstif security update

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.
