CVE-2022-3204

A vulnerability was found in unbound. The attack can cause a resolver to spend a lot of time and resources resolving records under a malicious delegation point where a considerable number of unresponsive NS records reside. This issue can trigger high CPU usage in some resolver implementations that continually look in the cache for resolved NS records in that delegation, leading to degraded performance and, eventually, a denial of service in orchestrated attacks.
