Descriptions

ISC BIND 9.8.x before 9.8.4-P1 and 9.9.x before 9.9.2-P1, when DNS64 is enabled, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted query.

ISC BIND v9.8.x antes de v9.8.4-P1 y v9.9.x antes de v9.9.2-P1, cuando DNS64 está activado, permite a atacantes remotos provocar una denegación de servicio (error de aserción y salida del demonio) a través de una consulta manipulada.

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. DNS64 is used to automatically generate DNS records so IPv6 based clients can access IPv4 systems through a NAT64 server. A flaw was found in the DNS64 implementation in BIND. If a remote attacker sent a specially-crafted query to a named server, named could exit unexpectedly with an assertion failure. Note that DNS64 support is not enabled by default.
