Are Application-layer Loop DoS Attacks relevant for bind9?
A new document were shared to me from our security team: <>
They are mentioning DNS, but it seems to be not a problem for any well behaving DNS server. Have you seen this paper already? Do you have already some stance for described attacks? To me it seems this should not affect any well behaving resolver or its client.
Have you already assessed this kind of attack, whether it is relevant on bind9 in any well configured instance? Can you confirm whether this strange thing is known to be relevant or irelevant to bind9 versions?
