    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
