    openvpn vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    
    Summary:
    
    OpenVPN could be made to expose sensitive information over the network.
    
    Software Description:
    - openvpn: virtual private network software
    
    Details:
    
    It was discovered that OpenVPN incorrectly handled HMAC comparisons when
    running in UDP mode. If a remote attacker were able to perform a
    man-in-the-middle attack, this flaw could possibly be used to perform a
    plaintext recovery attack.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      openvpn                         2.2.1-8ubuntu1.3
    
    In general, a standard system update will make all the necessary changes.
