Fixes multiple CVEs. Upstream changelog is
https://ftp.isc.org/isc/bind9/9.16.37/CHANGES

CVEs fixed:

CVE-2022-3924: Fix serve-stale crash when recursive clients soft quota
			is reached.

CVE-2022-3736: Handle RRSIG lookups when serve-stale is active.

CVE-2022-3094: An UPDATE message flood could cause named to exhaust all
			available memory. This flaw was addressed by adding a
			new "update-quota" statement that controls the number of
			simultaneous UPDATE messages that can be processed or
			forwarded. The default is 100. A stats counter has been
			added to record events when the update quota is
			exceeded, and the XML and JSON statistics version
			numbers have been updated.
