certain filenames when processing input. If a user or an automated
system were tricked into running lintian on a specially crafted set of
files, a remote attacker could execute arbitrary code with user
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."
