Official description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-15, a memory leak in the ASHLAR image writer allows an attacker to exhaust process memory by providing a crafted image that results in small objects that are allocated but never freed. Version 7.1.2-15 contains a patch.
