Vulnerability Description
If the auth responds very slowly and the records expire in between, the capping of TTLs is not enforced for lack of data. This does not happen on regular resolve as then then the
child records are used immediately if not expired and thus valid, or the
records are expired, and in that case not used. So this case
can only happen if almost expired records are used to refresh the
authoritative NS records.
