Bob 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. For the stable distribution (jessie), this problem has been fixed in version 8:6.8.9.9-5+deb8u3. We recommend that you upgrade your imagemagick packages.
