  - named in ISC BIND allows remote attackers to cause a denial of service via a DNAME record in the answer section
  of a response to a recursive query, related to db.c and resolver.c. (CVE-2016-8864)

  - named in ISC BIND allows remote attackers to cause a denial of service via a malformed response to an RTYPE ANY
  query. (CVE-2016-9131)

  - named in ISC BIND allows remote attackers to cause a denial of service via a response containing an
  inconsistency among the DNSSEC-related RRsets. (CVE-2016-9147)

  - named in ISC BIND allows remote attackers to cause a denial of service via a crafted DS resource record in an
  answer. (CVE-2016-9444)");
