ImageMagick 6.x < 6.9.7-5 / 7.x < 7.0.4-5 tga.c WriteTGAImage() Assertion Failure 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 6.9.7-5 or 7.x prior to 7.0.4-5. It is, therefore, affected
by a denial of service vulnerability in the WriteTGAImage() function
in coders/tga.c due to improper handling of TGA files. An
unauthenticated, remote attacker can exploit this, by convincing a
user to convert a specially crafted image to a TGA file, to cause a
denial of service condition.

Solution :

Upgrade to ImageMagick version 6.9.7-5 / 7.0.4-5 or later. Note that
you may also need to manually uninstall the vulnerable version from
the system.

Risk factor :

Medium / CVSS Base Score : 4.3
