escape shell meta-characters during 'Open Link' actions. If a remote
attacker tricked a user into opening a specially crafted URI, they
could execute arbitrary commands with the user's privileges.

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."
