Descriptions

A denial of service flaw was found in the way BIND handled DNSSEC validation. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response.

Se encontró un fallo de denegación de servicio en la forma en que BIND maneja la comprobación de DNSSEC. Un atacante remoto podría utilizar este fallo para hacer la salida nombrada inesperadamente con un error de aserción por medio de una respuesta DNS especialmente creada.

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. Security Fix: A denial of service flaw was found in the way BIND handled a query response containing CNAME or DNAME resource records in an unusual order. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS response.
