Original advisory details:

It was discovered that ImageMagick incorrectly handled certain PNG images.

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.
