CVE-2018-5741

To provide fine-grained controls over the ability to use Dynamic DNS (DDNS)
to update records in a zone, BIND 9 provides a feature called
update-policy. Various rules can be configured to limit the types of
updates that can be performed by a client, depending on the key used when
sending the update request. Unfortunately, some rule types were not
initially documented, and when documentation for them was added to the
Administrator Reference Manual (ARM) in change #3112, the language that was
added to the ARM at that time incorrectly described the behavior of two
rule types, krb5-subdomain and ms-subdomain. This incorrect documentation
could mislead operators into believing that policies they had configured
were more restrictive than they actually were. This affects BIND versions
prior to BIND 9.11.5 and BIND 9.12.3.
