Severity:	normal
Title:	OpenMotif, LessTif: New libXpm buffer overflows
Date:	03/04/2005
Bugs:	#83655, #83656
ID:	200503-08

Synopsis

A new vulnerability has been discovered in libXpm, which is included in OpenMotif and LessTif, that can potentially lead to remote code execution.

Background

LessTif is a clone of OSF/Motif, which is a standard user interface toolkit available on Unix and Linux. OpenMotif also provides a free version of the Motif toolkit for open source applications.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
x11-libs/openmotif	< 2.2.3-r3	>= 2.2.3-r3	All supported architectures
x11-libs/lesstif	< 0.94.0-r2	>= 0.94.0-r2	All supported architectures

Description

Chris Gilbert discovered potentially exploitable buffer overflow cases in libXpm that weren't fixed in previous libXpm security advisories.

Impact

A carefully-crafted XPM file could crash applications making use of the OpenMotif or LessTif toolkits, potentially allowing the execution of arbitrary code with the privileges of the user running the application.

Workaround

There is no known workaround at this time.

Resolution

All OpenMotif users should upgrade to an unaffected version:

    # emerge --sync
    # emerge --ask --oneshot --verbose x11-libs/openmotif

All LessTif users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-libs/lesstif-0.94.0-r2"
