apt vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

An attacker could trick APT into installing altered source packages.

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

Details:

Jakub Wilk discovered that APT did not correctly validate signatures when
downloading source packages. If a remote attacker were able to perform a
man-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 LTS:
  apt                             1.0.1ubuntu2.1

Ubuntu 13.10:
  apt                             0.9.9.1~ubuntu3.2

Ubuntu 12.04 LTS:
  apt                             0.8.16~exp12ubuntu10.17

Ubuntu 10.04 LTS:
  apt                             0.7.25.3ubuntu9.15

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