Action Type Old Value New Value Removed Translation PowerDNS Recursor anterior a 3.6.2 permite a atacantes remotos causar una denegación de servicio (degradación de rendimiento) a través de una solicitud para un nombre de dominio que provoca un número grande de consultas para resolver, tal y como fue demostrado mediante la resolución de dominios con ezdns.it de anfitrión. Added Translation PowerDNS Recursor en versiones anteriores a 3.6.2 no limita el encadenamiento de delegación, lo que permite a atacantes remotos provocar una denegación de servicio ("degradaciones de rendimiento") a través un número largo o infinito de referencias, según lo demostrado por la resolución de dominios alojados por ezdns.it. -
