USN-681-1: ImageMagick vulnerability

1 December 2008

imagemagick vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 7.10
  • Ubuntu 6.06 LTS

Software Description

  • imagemagick

Details

It was discovered that ImageMagick did not correctly handle certain malformed XCF images. If a user were tricked into opening a specially crafted image with an application that uses ImageMagick, an attacker could cause a denial of service and possibly execute arbitrary code with the user’s privileges.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.10
imagemagick - 7:6.2.4.5.dfsg1-2ubuntu1.1
Ubuntu 6.06 LTS
imagemagick - 6:6.2.4.5-0.6ubuntu0.8

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

After a standard system upgrade you need to restart any applications that use ImageMagick, such as OpenOffice.org and Inkscape, to effect the necessary changes.
