ImageMagick 6.x < 6.9.7-9 / 7.x < 7.0.4-10 webp.c ReadWEBPImage() File Descriptor Exhaustion DoS

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

An application installed on the remote Windows host is affected by a
denial of service vulnerability.

Description :

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.

Solution :

Upgrade to ImageMagick version 6.9.7-9 / 7.0.4-10 or later. Note that
you may also need to manually uninstall the vulnerable version from
the system.
