Descriptions

iterator.c in NLnet Labs Unbound before 1.5.1 does not limit delegation chaining, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a large or infinite number of referrals.

iterator.c en NLnet Labs Unbound anterior a 1.5.1 no limita el encadenamiento de la delegación, lo que permite a atacantes remotos causar una denegación de servicio (consumo de memoria y CPU) a través de un número grande o infinito de remisiones.

A denial of service flaw was found in unbound that an attacker could use to trick the unbound resolver into following an endless loop of delegations, consuming an excessive amount of resources.
