Synopsis:          Updated lesstif package fixes image vulnerability
Advisory ID:       RHSA-2005:004-01
Advisory URL:      https://access.redhat.com/errata/RHSA-2005:004.html
Issue date:        2005-01-12
Updated on:        2005-01-12

CVE Names:         CAN-2004-0687 CAN-2004-0688 CAN-2004-0914
- ---------------------------------------------------------------------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.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
