Fixes the following security issue:
- CVE-2020-8625: When tkey-gssapi-keytab or tkey-gssapi-credential was
configured, a specially crafted GSS-TSIG query could cause a buffer
overflow in the ISC implementation of SPNEGO (a protocol enabling
negotiation of the security mechanism to use for GSSAPI authentication).
This flaw could be exploited to crash named. Theoretically, it also
enabled remote code execution, but achieving the latter is very difficult
in real-world conditions

Fixes the following security issues:
- (9.11.18) DNS rebinding protection was ineffective when BIND 9 is
configured as a forwarding DNS server. Found and responsibly reported by
Tobias Klein. [GL #1574]
- (9.11.19) To prevent exhaustion of server resources by a maliciously
configured domain, the number of recursive queries that can be triggered
by a request before aborting recursion has been further limited. Root and
top-level domain servers are no longer exempt from the
max-recursion-queries limit. Fetches for missing name server address
records are limited to 4 for any domain. This issue was disclosed in
CVE-2020-8616. [GL #1388]
- (9.11.19) Replaying a TSIG BADTIME response as a request could trigger an

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

* 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.
