Descriptions

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.
