An issue has been found in PowerDNS Recursor before 4.1.18, 4.2.x before
4.2.5, and 4.3.x before 4.3.5. A remote attacker can cause the cached
records for a given name to be updated to the Bogus DNSSEC validation
state, instead of their actual DNSSEC Secure state, via a DNS ANY query.
This results in a denial of service for installation that always validate
(dnssec=validate), and for clients requesting validation when on-demand
validation is enabled (dnssec=process).
