netty-resolver-dns: Netty DNS resolver: DNS Cache Poisoning via predictable transaction IDs

A flaw was found in Netty's DNS resolver component. This vulnerability arises from the use of a predictable pseudo-random number generator PRNG for DNS transaction IDs and a static User Datagram Protocol UDP source port. This combination significantly reduces the randomness of DNS queries, making...

ldns: ldns: Off-path poisoning attacks due to insufficient query-response matching

A flaw was found in ldns. When applications use ldns as a resolver over User Datagram Protocol UDP, it fails to properly match the query's destination address and port with the response's source address and port. Additionally, the query ID and question are not matched with the response. This...
