"Several security vulnerabilities were discovered in ImageMagick, an
image manipulation program, that allow remote attackers to cause a
denial of service via CPU exhaustion (infinite loop) or heap-based
buffer overreads with a crafted image file.

For Debian 7 'Wheezy', these problems have been fixed in version
8:6.7.7.10-5+deb7u22.

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."
