imagemagick vulnerabilities
==========================================================================

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

- Ubuntu 16.04 ESM
- Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in ImageMagick.

Software Description:
- imagemagick: Image manipulation programs and library

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.
If a user or automated system were tricked into opening a specially crafted
PNG file, an attacker could use this issue to cause ImageMagick to stop
responding, resulting in a denial of service, or possibly obtain the
contents of arbitrary files by including them into images.

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 ESM:
