    bind9 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.10
    - 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 input received by the rndc
    control channel. A remote attacker could possibly use this issue to cause
    Bind to crash, resulting in a denial of service. (CVE-2016-1285)
    
    It was discovered that Bind incorrectly parsed resource record signatures
    for DNAME resource records. A remote attacker could possibly use this issue
    to cause Bind to crash, resulting in a denial of service. (CVE-2016-1286)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.10:
      bind9                           1:9.9.5.dfsg-11ubuntu1.3
    
    Ubuntu 14.04 LTS:
      bind9                           1:9.9.5.dfsg-3ubuntu0.8
    
    Ubuntu 12.04 LTS:
      bind9                           1:9.8.1.dfsg.P1-4ubuntu0.16
