Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-09-21 14:48:55 UTC
"The attack can cause a resolver to spend a lot of time/resources resolving records under a malicious delegation point where a considerable number of unresponsive NS records reside. It can trigger high CPU usage in some resolver implementations that continually look in the cache for resolved NS records in that delegation. This can lead to degraded performance and eventually denial of service in orchestrated attacks."

Please bump to 1.16.3.
