Description Sam Fowler 2018-02-08 06:27:54 UTC 
The AcquireCacheNexus function in magick/pixel_cache.c in GraphicsMagick before 1.3.28 can allow an attacker to cause a denial of service (heap overwrite) or possibly have unspecified other impact via a crafted image file, because a pixel staging area is not used.
