Synopsis

Multiple vulnerabilities have been discovered in ImageMagick, possibly resulting in arbitrary code execution or a Denial of Service.

2. Impact Information

Background

ImageMagick is a collection of tools and libraries for manipulating various image formats.

Description

regenrecht reported multiple infinite loops in functions ReadDCMImage() and ReadXCFImage() (CVE-2007-4985), multiple integer overflows when handling certain types of images (CVE-2007-4986, CVE-2007-4988), and an off-by-one error in the ReadBlobString() function (CVE-2007-4987).

Impact

A remote attacker could entice a user to open a specially crafted image, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application, or an excessive CPU consumption. Note that applications relying on ImageMagick to process images can also trigger the vulnerability.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All ImageMagick users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/imagemagick-6.3.5.10"
