processing certain files. If a user or automated system were tricked
into opening a specially crafted file, an attacker could cause
icoutils to crash, resulting in a denial of service, or possibly
execute arbitrary code.

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."
