CVE-2024-1975 SIG(0) can be used to exhaust CPU resources

If a server hosts a zone containing a "KEY" Resource Record, or a resolver DNSSEC-validates a "KEY" Resource Record from a DNSSEC-signed domain in cache, a client can exhaust resolver CPU resources by sending a stream of SIG0 signed requests. This issue affects BIND 9 versions 9.0.0 through...
