"The version of ImageMagick installed on the remote Windows host is 6.x
prior to 6.9.7-9 or 7.x prior to 7.0.4-10. It is, therefore, affected
by a denial of service vulnerability in the ReadWEBPImage() function
in coders/webp.c due to improper handling of WEBP files. An
unauthenticated, remote attacker can exploit this, by convincing a
user to open a specially crafted WEBP file, to exhaust available file
descriptors and cause a denial of service condition.");
