Acknowledgements

Red Hat would like to thank ISC for reporting this issue.

Mitigation

Restrict access to the control channel (by using the "controls" configuration statement in named.conf) to allow connection only from trusted systems.

Note that if no "controls" statement is present, named defaults to allowing control channel connections only from localhost (127.0.0.1 and ::1) if and only if the file rndc.key exists in the configuration directory and contains valid key syntax. If rndc.key is not present and no "controls" statement is present in named.conf, named will not accept commands on the control channel.
