when unpacking source packages. If a user or an automated system were
tricked into unpacking a specially crafted source package, a remote
attacker could modify files outside the target unpack directory,
leading to a denial of service or potentially gaining access to the
system.

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."
