The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.

Security Fix(es):

* bind: BIND does not sufficiently limit the number of fetches performed
when processing referrals (CVE-2020-8616)

* bind: A logic error in code which checks TSIG validity can be used to
trigger an assertion failure in tsig.c (CVE-2020-8617)
