Andrei Nigmatulin discovered that a Photoshop Document (PSD) file with
more than 24 layers could trigger a heap overflow.
Impact
======
An attacker could potentially design a mailicous PSD image file to
cause arbitrary code execution with the permissions of the user running
ImageMagick.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ImageMagick users should upgrade to the latest version:
