USN-2246-1: APT vulnerability

17 June 2014

An attacker could trick APT into installing altered source packages.



  • apt - Advanced front-end for dpkg


Jakub Wilk discovered that APT did not correctly validate signatures when
downloading source packages. If a remote attacker were able to perform a
machine-in-the-middle attack, this flaw could potentially be used to install
altered source packages.

Update instructions

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

Ubuntu 14.04
Ubuntu 13.10
Ubuntu 12.04
Ubuntu 10.04

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