Descriptions

named in ISC BIND 9.x before 9.9.7-P2 and 9.10.x before 9.10.2-P3 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via TKEY queries.

Vulnerabilidad identificada en ISC BIND 9.x en versiones anteriores a 9.9.7-P2 y 9.10.x en versiones anteriores a 9.10.2-P3, permite a atacantes remotos causar una denegación de servicio (fallo en la comprobación de REQUIRE y salida del demonio) a través de consultas TKEY.

A flaw was found in the way BIND handled requests for TKEY DNS resource records. A remote attacker could use this flaw to make named (functioning as an authoritative DNS server or a DNS resolver) exit unexpectedly with an assertion failure via a specially crafted DNS request packet.
