• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• imagemagick - Image manipulation programs and library

Details

USN-3142-1 fixed vulnerabilities in ImageMagick. The security fixes
introduced a regression with text labels and a regression with the text
coder. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that ImageMagick incorrectly handled certain malformed
image files. If a user or automated system using ImageMagick were tricked
into opening a specially crafted image, an attacker could exploit this to
cause a denial of service or possibly execute code with the privileges of
the user invoking the program.
