The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; (2) Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referrals to conduct cache poisoning against recursive resolvers, related to insufficient randomness of DNS transaction IDs and source ports, aka "DNS Insufficient Socket Entropy Vulnerability" or "the Kaminsky bug."
The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; (2) Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referrals to conduct cache poisoning against recursive resolvers, related to insufficient randomness of DNS transaction IDs and source ports, aka "DNS Insufficient Socket Entropy Vulnerability" or "the Kaminsky bug."
El protocolo DNS, como es implementado en (1) BIND 8 y 9 en versiones anteriores a 9.5.0-P1, 9.4.2-P1 y 9.3.5-P1; (2) Microsoft DNS en Windows 2000 SP4, XP SP2 y SP3 y Server 2003 SP1 y SP2; y otras implementaciones permiten a atacantes remotos suplantar el tráfico DNS a través de un ataque de un cumpleaños que usa referencias in-bailiwick para llevar a cabo un envenenamiento del caché contra resolutores recursivos, relacionado con la insifuciente aleatoriedad de la ID de la transacción DNS y los puertos de origen, vulnerabilidad también conocida como "DNS Insufficient Socket Entropy Vulnerability" o "the Kaminsky bug".
