Ubuntu Security Notice (C) 2011-2013 Canonical, Inc. / NASL script (C) 2011-2013 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.
Update the affected apt package.
