Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
It was discovered that the apt-key utility incorrectly verified GPG
keys when downloaded via the net-update option. If a remote attacker
were able to perform a man-in-the-middle attack, this flaw could
potentially be used to install altered packages. This update corrects
the issue by disabling the net-update option completely. A future
update will re-enable the option with corrected verification.
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.
Update the affected apt package.
