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
quota, it was possible for 'named' to enter an infinite
callback loop and crash due to stack overflow. This has
been fixed. (CVE-2023-2911) [GL #4089]
Resolves: CVE-2023-2911
