file, an attacker could crash tar or possibly execute arbitrary code
with the privileges of the user invoking the program.

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.
