From ${URL} :


A vulnerability has been reported in GraphicsMagick, which can be exploited by malicious people to 
cause a DoS (Denial of Service).

The vulnerability is caused due to an error within the "ExportAlphaQuantumType()" function 
(magick/export.c) when exporting 8-bit RGBA images and can be exploited to cause a crash.

The vulnerability is reported in versions prior to 1.3.18.

Update to version 1.3.18.
