A vulnerability was discovered in graphicsmagick, a collection of image processing tools, that results in a heap overflow in 32-bit applications because of a signed overflow on range check in the HuffmanDecodeImage function.

For Debian 8 Jessie, this problem has been fixed in version 1.3.20-3+deb8u10.

We recommend that you upgrade your graphicsmagick packages.
