imagemagick regression
A security issue affects these releases of Ubuntu and its derivatives:
USN-3363-1 caused a regression in ImageMagick.
Software description
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.
