Package        : imagemagick
Version        : 8:6.7.7.10-5+deb7u22
CVE ID         : CVE-2017-18271 CVE-2017-18273 CVE-2018-11251

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.
