Descriptions

PowerDNS Recursor before 3.6.2 does not limit delegation chaining, which allows remote attackers to cause a denial of service ("performance degradations") via a large or infinite number of referrals, as demonstrated by resolving domains hosted by ezdns.it.

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.

Florian Maury from ANSSI discovered a flaw in pdns-recursor, a maliciously-constructed zones or a rogue server could affect the performance of pdns-recursor, thus leading to resource exhaustion and a potential denial-of-service.
