An issue was discovered in MaraDNS Deadwood through 3.5.0021 that allows
variant V1 of unintended domain name resolution. A revoked domain name can
still be resolvable for a long time, including expired domains and
taken-down malicious domains. The effects of an exploit would be widespread
and highly impactful, because the exploitation conforms to de facto DNS
specifications and operational practices, and overcomes current mitigation
patches for “Ghost” domain names.
