ImageMagick: EXIF buffer overflow — GLSA 200411-11

ImageMagick contains an error in boundary checks when handling EXIF information, which could lead to arbitrary code execution.

Affected packages

Package 	media-gfx/imagemagick on all architectures
Affected versions 	< 6.1.3.2
Unaffected versions 	>= 6.1.3.2

Background

ImageMagick is a collection of tools to read, write and manipulate images in many formats.

Description

ImageMagick fails to do proper bounds checking when handling image files with EXIF information.

Impact

An attacker could use an image file with specially-crafted EXIF information to cause arbitrary code execution with the permissions of the user running ImageMagick.

Workaround

There is no known workaround at this time.

Resolution

All ImageMagick users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.1.3.2"
