    Software Description:
    - bind9: Internet Domain Name Server
    Toshifumi Sakaguchi discovered that Bind incorrectly handled memory. A
    remote attacker could possibly use this issue to cause Bind to consume
    resources, leading to a denial of service. This issue only affected Ubuntu
    18.04 LTS and Ubuntu 18.10. (CVE-2018-5744)
    It was discovered that Bind incorrectly handled certain trust anchors when
    used with the "managed-keys" feature. A remote attacker could possibly use
    this issue to cause Bind to crash, resulting in a denial of service.
    It was discovered that Bind incorrectly handled certain controls for zone
    transfers, contrary to expectations. (CVE-2019-6465)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 18.10:
      bind9                           1:9.11.4+dfsg-3ubuntu5.1
    Ubuntu 18.04 LTS:
      bind9                           1:9.11.3+dfsg-1ubuntu1.5
    Ubuntu 16.04 LTS:

      bind9                           1:9.9.5.dfsg-3ubuntu0.19
