An updated lesstif package that fixes flaws in the Xpm library is now available for Red Hat Enterprise Linux 2.1.. - --------------------------------------------------------------------- Red Hat Security Advisory 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 Product: Red Hat Enterprise Linux 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 Network to download andupdate your packages.
