Gentoo Linux Security Advisory

Title: ImageMagick: EXIF buffer overflow (GLSA 200411-11)
Severity: normal
Exploitable: remote
Date: November 06, 2004
Bug(s): #69825
ID: 200411-11

Synopsis

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

Background

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

Affected Packages

Package: media-gfx/imagemagick
Vulnerable: < 6.1.3.2
Unaffected: >= 6.1.3.2
Architectures: All supported architectures


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