DESCRIPTION:
Florian Weimer has discovered a vulnerability in ImageMagick, which
potentially can be exploited by malicious people to compromise a
user's system.
The vulnerability is caused due to an error in the delegate code used
by various ImageMagick utilities (e.g. display, identify) when
handling an image filename. This can be exploited to execute
arbitrary commands when an image file with a filename containing
shell command is opened either via the command line or from the file
open dialog box.
Successful exploitation requires that the user is e.g. tricked into
downloading and saving an image file with a specially crafted
filename and opening it.
The vulnerability has been confirmed in version 6.2.5 compiled from
source (with default options). Other versions may also be affected.
SOLUTION:
Do not open image files with suspicious looking filenames.
