Debian DSA-3591-1 : imagemagick - security update
Critical Nessus Plugin ID 91430
SynopsisThe remote Debian host is missing a security-related update.
DescriptionBob Friesenhahn from the GraphicsMagick project discovered a command injection vulnerability in ImageMagick, a program suite for image manipulation. An attacker with control on input image or the input filename can execute arbitrary commands with the privileges of the user running the application.
This update removes the possibility of using pipe (|) in filenames to interact with imagemagick.
It is important that you upgrade the libmagickcore-6.q16-2 and not just the imagemagick package. Applications using libmagickcore-6.q16-2 might also be affected and need to be restarted after the upgrade.
SolutionUpgrade the imagemagick packages.
For the stable distribution (jessie), this problem has been fixed in version 8:18.104.22.168-5+deb8u3.
