    Ubuntu Security Notice USN-1385-1
    March 06, 2012
    
    apt vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.10
    - Ubuntu 11.04
    
    Summary:
    
    An attacker could trick APT into installing altered packages.
    
    Software Description:
    - apt: Advanced front-end for dpkg
    
    Details:
    
    Simon Ruderich discovered that APT incorrectly handled repositories that
    use InRelease files. The default Ubuntu repositories do not use InRelease
    files, so this issue only affected third-party repositories. 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 11.10:
      apt                             0.8.16~exp5ubuntu13.2
    
    Ubuntu 11.04:
      apt                             0.8.13.2ubuntu4.4
    
    In general, a standard system update will make all the necessary changes.
