Synopsis
=======

libXpm contains several vulnerabilities that could lead to a Denial of Service and arbitrary code execution.



Background
=========

libXpm is a pixmap manipulation library for the X Window System, included in both X.Org and XFree86.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-base/xorg-x11 < 6.8.0-r3 >= 6.8.0-r3
*>= 6.7.0-r3
2 x11-base/xfree < 4.3.0-r8 >= 4.3.0-r8
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
==========

Several issues were discovered in libXpm, including integer overflows, out-of-bounds memory accesses, insecure path traversal and an endless loop.

Impact
=====

An attacker could craft a malicious pixmap file and entice a user to use it with an application linked against libXpm. This could lead to Denial of Service or arbitrary code execution.

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-x11-6.7.0-r3"

All XFree86 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-base/xfree-x11-4.3.0-r8"
