Summary:

Details:
USN-5855-1 fixed vulnerabilities in ImageMagick. This update provides the
corresponding updates for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.
Original advisory details:
It was discovered that ImageMagick incorrectly handled certain PNG images.

contents of arbitrary files by including them into images.
