A type conversion flaw leading to an out-of-bounds heap buffer read was found in the way libpng, a library of functions for manipulation PNG image format files, performed expansion of certain iCCP, iTXt, and zTXt PNG image file chunks.

A remote attacker could provide a specially-crafted Portable Network Graphics (PNG) image file, which once opened in an application, linked against libpng, could lead to denial of service or in some cases, execution of arbitrary code with permission of the user running such an application.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 13.0, Thunderbird before 13.0, and SeaMonkey before 2.10 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) methodjit/ImmutableSync.cpp, (2) the JSObject::makeDenseArraySlow function in js/src/jsarray.cpp, and unknown other components.

ImageMagick 6.7.5-7 and earlier allows remote attackers to cause a denial of service (infinite loop and hang) via a crafted image whose IFD contains IOP tags that all reference the beginning of the IDF.

The JPEGWarningHandler function in coders/jpeg.c in ImageMagick before 6.7.6-3 allows remote attackers to cause a denial of service (memory consumption) via a JPEG image with a crafted sequence of restart markers.

ImageMagick 6.7.5-7 and earlier allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via crafted offset and count values in the ResolutionUnit tag in the EXIF IFD0 of an image.
