"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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
