"The version of ImageMagick installed on the remote Windows host is 6.x
prior to 6.9.7-3. It is, therefore, affected by a remote code
execution vulnerability in the ReadPSDLayers() function in psd.c due
to improper validation of PSB files. An unauthenticated, remote
attacker can exploit this, by convincing a user to open a specially
crafted PSD file, to cause a denial of service condition or the
execution of arbitrary code.");
