ImageMagick -- multiple vulnerabilities

Multiple vulnerabilities have been discovered in ImageMagick.

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.

Sign extension error in the ReadDIBImage function in
ImageMagick before 6.3.5-9 allows context-dependent attackers
to execute arbitrary code via a crafted width value in an
image file, which triggers an integer overflow and a
heap-based buffer overflow.
