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

USN-3363-1 caused a regression in ImageMagick.

Software Description

  • imagemagick - Image manipulation programs and library


USN-3363-1 fixed vulnerabilities in ImageMagick. The update caused a regression for certain users when processing images. The problematic patch has been reverted pending further investigation.

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.
