ImageMagick before 6.2.4.2-r1 allows local users in the portage group to increase privileges via a shared object in the Portage temporary build directory, which is added to the search path allowing objects in it to be loaded at runtime.
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.
