Descriptions

ISC BIND 9.0.x through 9.8.x, 9.9.0 through 9.9.6, and 9.10.0 through 9.10.1 does not limit delegation chaining, which allows remote attackers to cause a denial of service (memory consumption and named crash) via a large or infinite number of referrals.

ISC BIND 9.0.x hasta 9.8.x, 9.9.0 hasta 9.9.6, y 9.10.0 hasta 9.10.1 no limita el encadenamiento de la delegación, lo que permite a atacantes remotos causar una denegación de servicio (consumo de memoria y caída del nombrado) a través de un número grande o infinito de referencias.

A denial of service flaw was found in the way BIND followed DNS delegations. A remote attacker could use a specially crafted zone containing a large number of referrals which, when looked up and processed, would cause named to use excessive amounts of memory or crash.
