- apt - Advanced front-end for dpkg
Details
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 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.
