Descriptions

The dns_db_findrdataset function in db.c in named in ISC BIND 9.4 before 9.4.3-P3, 9.5 before 9.5.1-P3, and 9.6 before 9.6.1-P1, when configured as a master server, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via an ANY record in the prerequisite section of a crafted dynamic update message, as exploited in the wild in July 2009.

La función dns_db_findrdataset en db.c en "named" en ISC BIND v9.4 anterior a v9.4.3-P3, v9.5 anterior a v9.5.1-P3, y v9.6 anterior a v9.6.1-P1, cuando está configurado como un servidor maestro, permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de cualquier registro en la sección prerequerida de un mensaje de actualización dinámico manipulado, tal como se ha explotado en julio de 2009.

It was discovered that the BIND DNS server terminates when processing a specially crafted dynamic DNS update. This vulnerability affects all BIND servers which serve at least one DNS zone authoritatively, as a master, even if dynamic updates are not enabled. The default Debian configuration for resolvers includes several authoritative zones, too, so resolvers are also affected by this issue unless these zones have been removed.
