The XWD Decoder in ImageMagick before 6.2.2.3, and GraphicsMagick before 1.1.6-r1, allows remote attackers to cause a denial of service (infinite loop) via an image with a zero color mask.
Heap-based buffer overflow in psd.c for ImageMagick 6.1.0, 6.1.7, and possibly earlier versions allows remote attackers to execute arbitrary code via a .PSD image file with a large number of layers.
Heap-based buffer overflow in the ReadPNMImage function in pnm.c for ImageMagick 6.2.1 and earlier allows remote attackers to cause a denial of service (application crash) via a PNM file with a small colors value.
