Update to 9.16.50:

Bug Fixes:
A regression in cache-cleaning code enabled memory use to grow
 significantly more quickly than before, until the configured
 max-cache-size limit was reached. This has been fixed.
Using rndc flush inadvertently caused cache cleaning to become
 less effective. This could ultimately lead to the configured
 max-cache-size limit being exceeded and has now been fixed.
The logic for cleaning up expired cached DNS records was
 tweaked to be more aggressive. This change helps with enforcing
 max-cache-ttl and max-ncache-ttl in a timely manner.
It was possible to trigger a use-after-free assertion when the
 overmem cache cleaning was initiated. This has been fixed.
 New Features:
Added RESOLVER.ARPA to the built in empty zones.
Security Fixes:
It is possible to craft excessively large numbers of resource
 record types for a given owner name, which has the effect of
 slowing down database processing. This has been addressed by
 adding a configurable limit to the number of records that can
 be stored per name and type in a cache or zone database. The
 default is 100, which can be tuned with the new
 max-types-per-name option. (CVE-2024-1737, bsc#1228256)
Validating DNS messages signed using the SIG(0) protocol (RFC
 2931) could cause excessive CPU load, leading to a
 denial-of-service condition. Support for SIG(0) message
 validation was removed from this version of named.
 (CVE-2024-1975, bsc#1228257)
When looking up the NS records of parent zones as part of
 looking up DS records, it was possible for named to trigger an
 assertion failure if serve-stale was enabled. This has been
 fixed. (CVE-2024-4076, bsc#1228258)");
