Bugs:	#83598
ID:	200503-15

Synopsis

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

Background

libXpm is a pixmap manipulation library for the X Window System, included in X.org.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
x11-base/xorg-x11	< 6.8.2-r1	>= 6.8.0-r5	All supported architectures

Description

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

Impact

A carefully-crafted XPM file could crash X.org, 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 X.org users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose x11-base/xorg-x11
