Descriptions

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.

Se descubrió un problema en MaraDNS Deadwood hasta 3.5.0021 que permite la variante V1 de resolución de nombres de dominio no deseada. Un nombre de dominio revocado aún se puede resolver durante mucho tiempo, incluidos dominios caducados y dominios maliciosos eliminados. Los efectos de un exploit serían generalizados y de gran impacto, porque la explotación se ajusta a las especificaciones y prácticas operativas de DNS de facto, y supera los parches de mitigación actuales para los nombres de dominio "Ghost"
