Description Victor Pereira 2018-02-12 07:19:43 UTC

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.
