Summary
The DNS protocol in RFC 1035 and updates allows remote attackers to cause a denial of service (resource consumption) by arranging for DNS queries to be accumulated for seconds such that responses are later sent in a pulsing burst (which can be considered traffic amplification in some cases) aka the "DNSBomb" issue.
