  <summary>Recommended update for bind</summary>
  <description>This update for bind fixes the following issues:

Update to release 9.16.33:

- CVE-2022-2795: Fixed potential performance degredation due to missing database lookup limits when processing large delegations (bsc#1203614).
- CVE-2022-3080: Fixed assertion failure when there was a stale CNAME in the cache for the incoming query and the stale-answer-client-timeout option is set to 0 (bsc#1203618).
- CVE-2022-38177: Fixed a memory leak that could be externally triggered in the DNSSEC verification code for the ECDSA algorithm (bsc#1203619).
- CVE-2022-38178: Fixed memory leaks that could be externally triggered in the DNSSEC verification code for the EdDSA algorithm (bsc#1203620).

- Add systemd drop-in directory for named service (bsc#1201689).
- Add modified createNamedConfInclude script and README-bind.chrootenv (bsc#1203250).

- Feature Changes:
  - Response Rate Limiting (RRL) code now treats all QNAMEs that are
  subject to wildcard processing within a given zone as the same
  name, to prevent circumventing the limits enforced by RRL.

- Zones using dnssec-policy now require dynamic DNS or
  inline-signing to be configured explicitly.

- A backward-compatible approach was implemented for encoding
  internationalized domain names (IDN) in dig and converting the
  domain to IDNA2008 form; if that fails,
  BIND tries an IDNA2003 conversion.

- The DNSSEC algorithms RSASHA1 and NSEC3RSASHA1 are now automatically
  disabled on systems where they are disallowed by the security policy.
  Primary zones using those algorithms need to be migrated to new algorithms
  prior to running on these systems, as graceful migration to different DNSSEC
  algorithms is not possible when RSASHA1 is disallowed by the operating system.

- Log messages related to fetch limiting have been improved to provide
  more complete information. Specifically, the final counts of allowed
  and spilled fetches are now logged before the counter object is destroyed.

- Non-dynamic zones that inherit dnssec-policy from the view or options
  blocks were not marked as inline-signed and therefore never scheduled
  to be re-signed. This has been fixed.

- The old max-zone-ttl zone option was meant to be superseded by
  the max-zone-ttl option in dnssec-policy; however, the latter option
  was not fully effective. This has been corrected: zones no longer load
  if they contain TTLs greater than the limit configured in dnssec-policy.
  For zones with both the old max-zone-ttl option and dnssec-policy
  configured, the old option is ignored, and a warning is generated.

- rndc dumpdb -expired was fixed to include expired RRsets,
  even if stale-cache-enable is set to no and the cache-cleaning time 
  window has passed. (jsc#SLE-24600)
