Synopsis
========
The X.Org X11 library contains multiple integer overflows, which could
lead to the execution of arbitrary code.
Background
==========
X.Org is an implementation of the X Window System. The X.Org X11
library provides the X11 protocol library files.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected

Description
===========
Multiple integer overflows have been reported in the XGetPixel()
function of the X.Org X11 library.
Impact
======
By enticing a user to open a specially crafted image, an attacker could
cause a Denial of Service or an integer overflow, potentially resulting
in the execution of arbitrary code with root privileges.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All X.Org X11 library users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/libX11-1.0.3-r2"
