Gentoo Linux Security Advisory

Title: ImageMagick: Multiple buffer overflows (GLSA 200705-13)
Severity: normal
Exploitable: remote
Date: May 10, 2007
Updated: June 07, 2007
Bug(s): #152672, #159567, #173186
ID: 200705-13

Synopsis


Multiple integer overflows have been discovered in ImageMagick allowing for
the execution of arbitrary code.


Background


ImageMagick is a collection of tools allowing various manipulations on
image files.


Affected Packages

Package: media-gfx/imagemagick
Vulnerable: < 6.3.3
Unaffected: >= 6.3.3
Architectures: All supported architectures


Description


iDefense Labs has discovered multiple integer overflows in ImageMagick
in the functions ReadDCMImage() and ReadXWDImage(), that are used to
process DCM and XWD files.


Impact


An attacker could entice a user to open specially crafted XWD or DCM
file, resulting in heap-based buffer overflows and possibly the
execution of arbitrary code with the privileges of the user running
ImageMagick. Note that this user may be httpd or any other account used
by applications relying on the ImageMagick tools to automatically
process images.


Workaround


There is no known workaround at this time.


Resolution


All ImageMagick users should upgrade to the latest version:
