images using the DOTRANGE tag. If a user or automated system were
tricked into opening a specially crafted TIFF image, a remote attacker
could crash the application, leading to a denial of service, or
possibly execute arbitrary code with user privileges.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
