Package        : imagemagick
Version        : 8:6.7.7.10-5+deb7u6
CVE ID         : CVE-2016-5118
Debian Bug     : 825799


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 libmagickcore5 and not just
the imagemagick package. Applications using libmagickcore5 might
also be affected and need to be restarted after the upgrade.

For Debian 7 "Wheezy", these problems have been fixed in version
8:6.7.7.10-5+deb7u6.

We recommend that you upgrade your imagemagick packages.
