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

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

- Ubuntu 11.04

Summary:

An attacker could trick APT into installing altered packages.

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

Details:

William Grant discovered that APT incorrectly validated inline GPG
signatures. 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 11.04:
  apt                             0.8.13.2ubuntu4.1

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