a6860b11-0dee-11eb-94ff-6805ca2fa271powerdns-recursor -- cache pollution

PowerDNS Team reports:

CVE-2020-25829: An issue has been found in PowerDNS Recursor where 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 installations that always validate (dnssec=validate) and for clients requesting validation when on-demand validation is enabled (dnssec=process).
