RHSA-2005:004 - Security Advisory
lesstif security update
Security Advisory: Moderate
An updated lesstif package that fixes flaws in the Xpm library is now
available for Red Hat Enterprise Linux 2.1.
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.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
