    libndp vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.04 LTS
    - Ubuntu 15.10
    
    Summary:
    
    libndp could be tricked into accepting an NDP message from outside the
    local network.
    
    Software Description:
    - libndp: Library for Neighbor Discovery Protocol
    
    Details:
    
    Julien Bernard discovered that libndp incorrectly performed origin checks
    when receiving Neighbor Discovery Protocol (NDP) messages. A remote
    attacker outside of the local network could use this issue to advertise a
    node as a router, causing a denial of service, or possibly to act as a man
    in the middle.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.04 LTS:
      libndp0                         1.4-2ubuntu0.16.04.1
    
    Ubuntu 15.10:
      libndp0                         1.4-2ubuntu0.15.10.1
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
