ImageMagick before 6.3.5-9 allows context-dependent attackers to cause a denial of service via a crafted image file that triggers (1) an infinite loop in the ReadDCMImage function, related to ReadBlobByte function calls; or (2) an infinite loop in the ReadXCFImage function, related to ReadBlobMSBLong function calls.

Multiple integer overflows in ImageMagick before 6.3.5-9 allow context-dependent attackers to execute arbitrary code via a crafted (1) .dcm, (2) .dib, (3) .xbm, (4) .xcf, or (5) .xwd image file, which triggers a heap-based buffer overflow.

Off-by-one error in the ReadBlobString function in blob.c in ImageMagick before 6.3.5-9 allows context-dependent attackers to execute arbitrary code via a crafted image file, which triggers the writing of a '\0' character to an out-of-bounds address.

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.
