CVE-2022-3924 named configured to answer from stale cache may terminate unexpectedly at recursive-clients soft quota

This issue can affect BIND 9 resolvers with stale-answer-enable yes; that also make use of the option stale-answer-client-timeout, configured with a value greater than zero. If the resolver receives many queries that require recursion, there will be a corresponding increase in the number of clien...
