Security release:

- CVE-2023-2828
- CVE-2023-2911

6192. [security] A query that prioritizes stale data over lookup
triggers a fetch to refresh the stale data in cache.
If the fetch is aborted for exceeding the recursion

been fixed. (CVE-2023-2911) [GL #4089]

6190. [security] Improve the overmem cleaning process to prevent the
cache going over the configured limit. (CVE-2023-2828)
[GL #4055]

6183. [bug] Fix a serve-stale bug where a delegation from cache
could be returned to the client. [GL #3950]

6173. [bug] Properly process extra "nameserver" lines in
resolv.conf otherwise the next line is not properly
processed. [GL #4066]

6169. [bug] named could crash when deleting inline-signing zones
with "rndc delzone". [GL #4054]
