(Red Hat Issues Fix for Open Motif) libXpm Integer and Stack Overflows May Let Remote Users Execute Arbitrary Code

SecurityTracker Alert ID: 1012384

SecurityTracker URL: http://securitytracker.com/id?1012384

CVE Reference: CAN-2004-0687 (Links to External Site)

Date: Dec 2 2004

Impact: Execution of arbitrary code via network, User access via network

Fix Available: Yes Vendor Confirmed: Yes

Description: Some vulnerabilities were reported in libXpm. A remote user may be able to execute arbitrary code on applications that use libXpm. Open Motif is affected.

The vendor reported that there are some integer overflows [CVE: CAN-2004-0687] and stack overflows [CVE: CAN-2004-0688] in the libXpm X Pixmap library, shipped as part of the X Window System.

A stack overflow is reported in xpmParseColors() in 'parse.c' that can be triggered by a specially crafted XPMv1 and XPMv2/3 file. A demonstration exploit file is available at:

http://scary.beasts.org/misc/doom.xpm

A stack overflow is reported in the reading of pixel values in the ParseAndPutPixels() function in 'create.c' and in the ParsePixels() function in 'parse.c'. A demonstration exploit file is available at:

http://scary.beasts.org/misc/doom2.xpm

An integer overflow is reported in the colorTable allocation in xpmParseColors() in 'parse.c'. The XpmCreateImageFromXpmImage, CreateXImage, ParsePixels, ParseAndPutPixels, and ParsePixels are affected.

The vendor credits Chris Evans with reporting these flaws. The advisory from Chris Evans is available at:

http://scary.beasts.org/security/CESA-2004-003.txt

Impact: A remote user can create a specially crafted image file that, when processed by an application using libXpm, will execute arbitrary code on the target system with the privileges of the target application.

Cause: Boundary error

Underlying OS: Linux (Red Hat Enterprise)

Underlying OS Comments: 2.1, 3

3. Problem description:

OpenMotif provides libraries which implement the Motif industry standard
graphical user interface.  

During a source code audit, Chris Evans and others 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 OpenMotif. 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 OpenMotif are advised to upgrade to these erratum packages, which
contain 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 and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:
