ImageMagick before 7.0.5-2 and GraphicsMagick before 1.3.24 use uninitialized memory in the RLE decoder, allowing an attacker to leak sensitive information from process memory space, as demonstrated by remote attacks against ImageMagick code in a long-running server process that converts image data on behalf of multiple users. This is caused by a missing initialization step in the ReadRLEImage function in coders/rle.c.

Affected: Ubuntu:14.04:LTS: imagemagick, Ubuntu:16.04:LTS: imagemagick

It was discovered that ImageMagick incorrectly handled certain malformed image files. If a user or automated system using ImageMagick were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or possibly execute code with the privileges of the user invoking the program.
