ReadOneJNGImage in coders/png.c in GraphicsMagick version 1.3.26 does not properly validate JNG data, leading to a denial of service (assertion failure in magick/pixel_cache.c, and application crash).

From the Ubuntu security team

It was discovered that GraphicsMagick incorrectly handled certain image files. An attacker could possibly use this issue to cause a denial of service or other unspecified impact.
