Multiple integer overflows in (1) the XGetPixel function in ImUtil.c in X.Org libx11 before 1.0.3, and (2) XInitImage function in xwd.c for ImageMagick, allow user-assisted remote attackers to cause a denial of service (crash) or obtain sensitive information via crafted images with large or negative values that trigger a buffer overflow.

Multiple integer overflows in ImageMagick before 6.2.9 allows user-assisted attackers to execute arbitrary code via crafted Sun Rasterfile (bitmap) images that trigger heap-based buffer overflows.

Heap-based buffer overflow in the libMagick component of ImageMagick 6.0.6.2 might allow attackers to execute arbitrary code via an image index array that triggers the overflow during filename glob expansion by the ExpandFilenames function.

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.
