"This update fixes several vulnerabilities in imagemagick: Various
memory handling problems and cases of missing or incomplete input
sanitising may result in denial of service if malformed MNG, JNG,
ICON, PALM, MPC, or PDB files are processed.

For Debian 7 'Wheezy', these problems have been fixed in version
8:6.7.7.10-5+deb7u15.

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."
