Kurt Seifried reports:

There is an issue in ImageMagick that is also present in GraphicsMagick. CVE-2011-3026 deals with libpng memory allocation, and limitations have been added so that a bad PNG can't cause the system to allocate a lot of memory and a denial of service. However on further investigation of ImageMagick, Tom Lane found that PNG malloc function (Magick_png_malloc) in turn calls AcquireMagickMemory with an improper size argument.
