Descriptions

buffer.c in named in ISC BIND 9.x before 9.9.7-P3 and 9.10.x before 9.10.2-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) by creating a zone containing a malformed DNSSEC key and issuing a query for a name in that zone.

Vulnerabilidad en buffer.c en nombrado en ISC BIND 9.x en versiones anteriores a 9.9.7-P3 y 9.10.x en versiones anteriores a 9.10.2-P4, permite a atacantes remotos causar una denegación de servicio (error de aserción y salida del demonio) mediante la creación de una zona de contención, una clave DNSSEC mal formada y la emisión de una consulta para un nombre en esa zona.

A denial of service flaw was found in the way BIND parsed certain malformed DNSSEC keys. A remote attacker could use this flaw to send a specially crafted DNS query (for example, a query requiring a response from a zone containing a deliberately malformed key) that would cause named functioning as a validating resolver to crash.
