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.

The Berkeley Internet Name Domain is an implementation of the Domain Name System protocols. BIND includes a DNS server ; a resolver library ; and tools for verifying that the DNS server is operating correctly. 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.
