Three issues have been found in graphicsmagick, a collection of image processing tools. They are basically a heap-based buffer over-read, heap-based buffer overflow and a use-after-free in different functions.

For Debian 8 Jessie, these problems have been fixed in version 1.3.20-3+deb8u8.

We recommend that you upgrade your graphicsmagick packages.
