Synopsis
========
An integer overflow in ImageMagick might allow remote attackers to
cause the remote execution of arbitrary code.
Background
==========
ImageMagick is a collection of tools and libraries for manipulating
various image formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/imagemagick < 6.5.2.9 >= 6.5.2.9
Description
===========
Tielei Wang has discovered that the XMakeImage() function in
magick/xwindow.c is prone to an integer overflow, possibly leading to a
buffer overflow.
Impact
======
A remote attacker could entice a user to open a specially crafted
image, possibly resulting in the remote execution of arbitrary code
with the privileges of the user running the application, or a Denial of
Service.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ImageMagick users should upgrade to an unaffected version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.5.2.9"
NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since June 4, 2009. It is likely that your system is already
no longer affected by this issue.
