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.
