Georgi Guninski discovered that APT did not properly validate imported
keyrings via apt-key net-update. USN-1475-1 added additional verification
for imported keyrings, but it was insufficient. If a remote attacker were
able to perform a machine-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.
