          "text": "A vulnerability named \"non-responsive delegation attack\" (NRDelegation attack) has been discovered in various DNS resolving software. The NRDelegation attack works by having a malicious delegation with a considerable number of non-responsive nameservers. The attack starts by querying a resolver for a record that relies on those unresponsive nameservers. The attack could cause a resolver to spend time/resources resolving records under a malicious delegation point where a considerable number of unresponsive NS records reside. It could trigger high CPU usage in some resolver implementations that continually look in the cache for resolved NS records in that delegation, which could lead to degraded performance and eventually denial of service in orchestrated attacks. Unbound does not suffer from high CPU usage, but still requires resources to resolve the malicious delegation. Unbound will continue to try to resolve the record until it reaches hard limits. Based on the nature of the attack and the replies, Unbound could reach different limits. From version 1.16.3 on, Unbound introduces fixes for better performance when under load by cutting opportunistic queries for nameserver discovery and DNSKEY prefetching and limiting the number of times a delegation point can issue a cache lookup for missing records.",
