Synopsis
========
GraphicsMagick improperly handles PALM and DCM images, potentially
resulting in the execution of arbitrary code.
Background
==========
GraphicsMagick is a collection of tools and libraries which support
reading, writing, and manipulating images in many major formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/graphicsmagick < 1.1.7-r3 >= 1.1.7-r3
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 GraphicsMagick, and possibly execute arbitrary code with the
privileges of the user running GraphicsMagick.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GraphicsMagick users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/graphicsmagick-1.1.7-r3"
