"Various vulnerabilities were discovered in graphicsmagick, a
collection of image processing tools and associated libraries,
resulting in denial of service, information disclosure, and a variety
of buffer overflows and overreads.

For Debian 8 'Jessie', these problems have been fixed in version
1.3.20-3+deb8u4.

We recommend that you upgrade your graphicsmagick 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."
