CVE-2004-1503

Estado: ModificadaMedia (5)—

Desbordamiento de entero en InitialDirContext en Java Runtime Environment (JRE) 1.4.2, 1.5.0 y posiblemente otras versiones, que permite a atacantes remotos provocar una denegación de servicio (excepción de Java y solicitudes DNS fallidas) mediante un gran número de solicitudes DNS, lo que hace que la variable xid dé la vuelta y se vuelva negativa.
