Description Stefan Cornelius 2012-03-29 06:02:49 EDT
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).

Proposed patch

Updated patch, this one also adds a test to avoid an overflow of the "number_bytes" value when the "components" field is too large.

Updated (clean up) patch

Same proposed patch, without the traces.
Comment 8 Stefan Cornelius 2012-04-10 10:53:09 EDT
The original patch for CVE-2012-0259 is insufficient. Upstream was notified and a new patch was published on [1]. As announced in [2], CVE-2012-1610 has been assigned to the insufficient fix of CVE-2012-0259.

Statement CVE-2012-1610:

Not vulnerable. This issue did not affect the versions of ImageMagick as shipped with Red Hat Enterprise Linux 6 as it did not backport the insufficient patch for CVE-2012-0259.
Comment 9 Pavel Alexeev 2012-04-11 09:28:58 EDT
Rawhide build which should fix it http://koji.fedoraproject.org/koji/taskinfo?taskID=3977291.
