Ubuntu 16.10 : apt regression (USN-3156-2)

high Nessus Plugin ID 96035

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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

Users on Ubuntu 16.10 should run the following commands at a terminal :

sudo dpkg --configure --pending sudo apt-get -f install

This update fixes the problem.

We apologize for the inconvenience.

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.

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.

Solution

Update the affected apt package.
