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). Se ha encontrado un problema en PowerDNS Recursor versiones anteriores a 4.1.18, versiones 4.2.x anteriores a 4.2.5 y versiones 4.3.x anteriores a 4.3.5. Un atacante remoto puede causar que los registros en caché para un nombre dado sean actualizados al estado de comprobación de Bogus DNSSEC, en lugar de su estado DNSSEC Secure real, por medio de una consulta ANY de DNS. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00036.html https://docs.powerdns.com/recursor/security-advisories/powerdns-advisory-2020-07.html https://security.gentoo.org/glsa/202012-19 •
