Description

The remote Windows host is running a version of ImageMagick prior to version 6.8.7-6. It is, therefore, affected by a memory corruption vulnerability related to PSD image file handling and the 'WritePSDImage' function. Exploitation of this issue could result in a denial of service or arbitrary code execution.
