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"
