Debian: DSA-3591-1: imagemagick security update
Summary
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 6.8.9.9-5+deb8u3.
We recommend that you upgrade your imagemagick packages.
