CVE-2012-3437

Status Candidate

Overview

The Magick_png_malloc function in coders/png.c in ImageMagick 6.7.8 and earlier does not use the proper variable type for the allocation size, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG file that triggers incorrect memory allocation.
