USN-3156-1 fixed vulnerabilities in APT. It also caused a bug in unattended-upgrades on that may require manual intervention to repair.

This update fixes the problem.


We apologize for the inconvenience.


Original advisory details:


Jann Horn discovered that APT incorrectly handled InRelease files. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to install altered packages.
