>From the release notes
(http://ftp.isc.org/isc/bind9/9.11.4-P2/RELEASE-NOTES-bind-9.11.4-P2.txt):
* There was a long-existing flaw in the documentation for ms-self,
krb5-self, ms-subdomain, and krb5-subdomain rules in update-policy
statements. Though the policies worked as intended, operators who
configured their servers according to the misleading documentation may
have thought zone updates were more restricted than they were; users of
these rule types are advised to review the documentation and correct
their configurations if necessary. New rule types matching the
previously documented behavior will be introduced in a future maintenance
release. [GL !708]
* named could crash during recursive processing of DNAME records when
deny-answer-aliases was in use. This flaw is disclosed in CVE-2018-5740.

CVE-2017-3142: An error in TSIG authentication can permit unauthorized zone

An attacker who is able to send and receive messages to an authoritative DNS
