RHSA-2004:494 - Security Advisory

Topic

Updated ImageMagick packages that fix various security vulnerabilities are
now available.

Description

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.
