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"
