    bind9 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.10
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Bind could be made to crash if it received specially crafted network
    traffic.
    
    Software Description:
    - bind9: Internet Domain Name Server
    
    Details:
    
    It was discovered that Bind incorrectly handled rewriting certain query
    responses when using both DNS64 and RPZ. A remote attacker could possibly
    use this issue to cause Bind to crash, resulting in a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.10:
      bind9                           1:9.10.3.dfsg.P4-10.1ubuntu1.3
    
    Ubuntu 16.04 LTS:
      bind9                           1:9.10.3.dfsg.P4-8ubuntu1.5
    
    Ubuntu 14.04 LTS:
      bind9                           1:9.9.5.dfsg-3ubuntu0.13
    
    Ubuntu 12.04 LTS:
      bind9                           1:9.8.1.dfsg.P1-4ubuntu0.21
    
    In general, a standard system update will make all the necessary changes.
