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"
