>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.

Fixes CVE-2018-5738: 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.

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

CVE-2017-3041: An error in TSIG authentication can permit unauthorized dynamic
updates
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 for the zone and service
being targeted may be able to manipulate BIND into accepting an unauthorized
dynamic update.

Security Fixes:
- rndc "" could trigger an assertion failure in named. This flaw is
disclosed in (CVE-2017-3138). [RT #44924]
- Some chaining (i.e., type CNAME or DNAME) responses to upstream
queries could trigger assertion failures. This flaw is disclosed in
CVE-2017-3137. [RT #44734]
- dns64 with break-dnssec yes; can result in an assertion failure. This
flaw is disclosed in CVE-2017-3136. [RT #44653]
- If a server is configured with a response policy zone (RPZ) that
rewrites an answer with local data, and is also configured for DNS64
address mapping, a NULL pointer can be read triggering a server
crash. This flaw is disclosed in CVE-2017-3135. [RT #44434]
- A coding error in the nxdomain-redirect feature could lead to an
assertion failure if the redirection namespace was served from a
local authoritative data source such as a local zone or a DLZ instead
of via recursive lookup. This flaw is disclosed in CVE-2016-9778.
[RT #43837]
- named could mishandle authority sections with missing RRSIGs,
triggering an assertion failure. This flaw is disclosed in
CVE-2016-9444. [RT #43632]
- named mishandled some responses where covering RRSIG records were
returned without the requested data, resulting in an assertion
failure. This flaw is disclosed in CVE-2016-9147. [RT #43548]
- named incorrectly tried to cache TKEY records which could trigger an
