CVE-2012-0259 ImageMagick: Out-of heap-based buffer read by processing crafted JPEG EXIF header tag value
Last modified: 2015-11-24 09:49:42 EST
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).
Red Hat would like to thank CERT-FI for reporting this issue. CERT-FI acknowledges Aleksis Kauppinen, Joonas Kuorilehto, Tuomas Parttimaa and Lasse Ylivainio of Codenomicon's CROSS project as the original reporters.
This issue affects the versions of the ImageMagick package, as shipped with Fedora release of 15 and 16.
