03 Oct 2024 — An attacker can publish a zone containing specific Resource Record Sets. Repeatedly processing and caching results for these sets can lead to a denial of service. Toshifumi Sakaguchi discovered that too permissive parsing of some resource record sets in the zone file parsing of PDNS Recursor could result in denial of service. • https://docs.powerdns.com/recursor/security-advisories/powerdns-advisory-2024-04.html • CWE-20: Improper Input Validation •

13 May 2024 — When incoming DNS over HTTPS support is enabled using the nghttp2 provider, and queries are routed to a tcp-only or DNS over TLS backend, an attacker can trigger an assertion failure in DNSdist by sending a request for a zone transfer (AXFR or IXFR) over DNS over HTTPS, causing the process to stop and thus leading to a Denial of Service. DNS over HTTPS is not enabled by default, and backends are using plain DNS (Do53) by default. Cuando la compatibilidad con DNS entrante sobre HTTPS está habilitada mediante... • http://www.openwall.com/lists/oss-security/2024/05/13/1 • CWE-20: Improper Input Validation •

25 Apr 2024 — A crafted response from an upstream server the recursor has been configured to forward-recurse to can cause a Denial of Service in the Recursor. The default configuration of the Recursor does not use recursive forwarding and is not affected. Una respuesta manipulada desde un servidor ascendente al que se ha configurado el recursor para reenviar puede causar una denegación de servicio en el recursor. La configuración predeterminada del Recursor no utiliza el reenvío recursivo y no se ve afectada.

13 Feb 2024 — Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. Ciertos aspectos DNSSEC del protocolo DNS (en RFC 4035 y RFC relacionados) permiten a ataca... • https://github.com/knqyf263/CVE-2023-50387 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

21 Jan 2023 — A remote attacker might be able to cause infinite recursion in PowerDNS Recursor 4.8.0 via a DNS query that retrieves DS records for a misconfigured domain, because QName minimization is used in QM fallback mode. This is fixed in 4.8.1. Un atacante remoto podría provocar una recursividad infinita en PowerDNS Recursor 4.8.0 a través de una consulta DNS que recupera registros DS para un dominio mal configurado, porque la minimización de QName se utiliza en el modo de reserva de QM. Esto se solucionó en 4.8.1. • http://www.openwall.com/lists/oss-security/2023/01/20/1 • CWE-674: Uncontrolled Recursion •

16 Oct 2020 — 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).
