Fixes the following security issues:
- named could crash during recursive processing of DNAME records when
deny-answer-aliases was in use. This flaw is disclosed in CVE-2018-5740.
[GL #387]
- When recursion is enabled but the allow-recursion and allow-query-cache
ACLs are not specified, they should be limited to local networks, but they
were inadvertently set to match the default allow-query, thus allowing
remote queries. This flaw is disclosed in CVE-2018-5738. [GL #309]
- Code change #4964, intended to prevent double signatures when deleting an
inactive zone DNSKEY in some situations, introduced a new problem during
zone processing in which some delegation glue RRsets are incorrectly
identified as needing RRSIGs, which are then created for them using the
current active ZSK for the zone. In some, but not all cases, the
newly-signed RRsets are added to the zone's NSEC/NSEC3 chain, but
incompletely -- this can result in a broken chain, affecting validation of
proof of nonexistence for records in the zone. [GL #771]
- named could crash if it managed a DNSSEC security root with managed-keys
and the authoritative zone rolled the key to an algorithm not supported by
BIND 9. This flaw is disclosed in CVE-2018-5745. [GL #780]
- named leaked memory when processing a request with multiple Key Tag EDNS
options present. ISC would like to thank Toshifumi Sakaguchi for bringing
this to our attention. This flaw is disclosed in CVE-2018-5744. [GL
#772]
- Zone transfer controls for writable DLZ zones were not effective as the
allowzonexfr method was not being called for such zones. This flaw is
disclosed in CVE-2019-6465. [GL #790]

>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
transfers
An attacker who is able to send and receive messages to an authoritative DNS
server and who has knowledge of a valid TSIG key name may be able to
circumvent TSIG authentication of AXFR requests via a carefully constructed
request packet. A server that relies solely on TSIG keys for protection with
no other ACL protection could be manipulated into:
* providing an AXFR of a zone to an unauthorized recipient
* accepting bogus NOTIFY packets
