First published: Wed Feb 07 2018(Updated: )
The AcquireCacheNexus function in magick/pixel_cache.c in GraphicsMagick before 1.3.28 allows remote attackers 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.
