Ubuntu Security Notice USN-3156-1
December 13, 2016

apt vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS


An attacker could trick APT into installing altered packages.

Software Description:
- apt: Advanced front-end for dpkg


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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.10:
  apt                             1.3.2ubuntu0.1

Ubuntu 16.04 LTS:
  apt                             1.2.15ubuntu0.2

Ubuntu 14.04 LTS:
  apt                             1.0.1ubuntu2.17

In general, a standard system update will make all the necessary changes.
