If the recursive-clients
quota is reached on a BIND 9 resolver configured with both stale-answer-enable yes;
and stale-answer-client-timeout 0;
, a sequence of serve-stale-related lookups could cause named
to loop and terminate unexpectedly due to a stack overflow. This issue affects BIND 9 versions 9.16.33 through 9.16.41, 9.18.7 through 9.18.15, 9.16.33-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
