    rpcbind vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.04
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    rpcbind could be made to crash or run programs if it received specially
    crafted network traffic.
    
    Software Description:
    - rpcbind: converts RPC program numbers into universal addresses
    
    Details:
    
    It was discovered that rpcbind incorrectly handled certain memory
    structures. A remote attacker could use this issue to cause rpcbind to
    crash, resulting in a denial of service, or possibly execute arbitrary
    code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.04:
      rpcbind                         0.2.1-6ubuntu3.1
    
    Ubuntu 14.04 LTS:
      rpcbind                         0.2.1-2ubuntu2.2
    
    Ubuntu 12.04 LTS:
      rpcbind                         0.2.0-7ubuntu1.3
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
