Vulnerability from csaf_redhat - Published: 2004-10-20 19:17 - Updated: 2025-11-21 17:27Summary
Red Hat Security Advisory: ImageMagick security update
Severity
Important
Notes
Topic: Updated ImageMagick packages that fix various security vulnerabilities are
now available.
Details: ImageMagick(TM) is an image display and manipulation tool for the X Window
System.
A heap overflow flaw was discovered in the ImageMagick image handler.
An attacker could create a carefully crafted BMP file in such a way that it
would cause ImageMagick to execute arbitrary code when processing the
image. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0827 to this issue.
A temporary file handling bug has been found in ImageMagick's libmagick
library. A local user could overwrite or create files as a different user
if a program was linked with the vulnerable library. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0455 to this issue.
Users of ImageMagick should upgrade to these updated packages, which
contain a backported patch, and is not vulnerable to this issue.

The imagemagick libmagick library 5.5 and earlier creates temporary files insecurely, which allows local users to create or overwrite arbitrary files.
Vendor Fix
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
Update Agent, use the following command:
up2date
For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:
http://www.redhat.com/docs/manuals/enterprise/
https://access.redhat.com/errata/RHSA-2004:494
Multiple buffer overflows in the ImageMagick graphics library 5.x before 5.4.4, and 6.x before 6.0.6.2, allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via malformed (1) AVI, (2) BMP, or (3) DIB files.
