A remote user can return a specially crafted query response that contains DNSSEC-related RRsets that are inconsistent with other RRsets in the same query response to trigger an assertion failure and cause target 'named' service to stop processing [CVE-2016-9147]. Versions 9.9.9-P4, 9.9.9-S6, 9.10.4-P4, and 9.11.0-P1 are affected.

A remote user can return a specially crafted query response that contains a DS resource record to trigger an assertion failure and cause target 'named' service to stop processing [CVE-2016-9444].

A remote user can send a specially crafted query to the target system that uses the nxdomain-redirect feature to cover a zone for which it provides authoritative service to cause the target 'named' service to stop processing [CVE-2016-9778].

Impact:   A remote user can cause the target 'named' service to stop processing.
