An out-of heap-based buffer read flaw was found in the way ImageMagick, an image display and manipulation tool for the X Window System, retrieved Exchangeable image file format (Exif) header tag information from certain JPEG files. A remote attacker could provide a JPEG image file, with EXIF header containing specially-crafted tag values, which once opened in some ImageMagick tool would lead to the crash of that tool (denial of service).
