Date: November 24, 2006
Bugs: #152672
ID: 200611-19

Synopsis
========
ImageMagick improperly handles PALM and DCM images, potentially
resulting in the execution of arbitrary code.
Background
==========
ImageMagick is a software suite to create, edit, and compose bitmap
images, that can also read, write, and convert images in many other
formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/imagemagick < 6.3.0.5 >= 6.3.0.5
Description
===========
M. Joonas Pihlaja has reported that a boundary error exists within the
ReadDCMImage() function of coders/dcm.c, causing the improper handling
of DCM images. Pihlaja also reported that there are several boundary
errors in the ReadPALMImage() function of coders/palm.c, similarly
causing the improper handling of PALM images.
Impact
======
An attacker could entice a user to open a specially crafted DCM or PALM
image with ImageMagick, and possibly execute arbitrary code with the
privileges of the user running ImageMagick.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ImageMagick users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.3.0.5"
