file names that were passed to the shell as part of a command. If a
remote attacker were able to generate specially crafted filenames (for
example, via Samba logging), they could execute arbitrary code with
root 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."
