Descriptions

Microsoft Windows XP SP3 does not validate addresses in certain IRP handler routines, which allows local users to write data to arbitrary memory locations, and consequently gain privileges, via a crafted address in an IOCTL call, related to (1) the MQAC.sys driver in the MQ Access Control subsystem and (2) the BthPan.sys driver in the Bluetooth Personal Area Networking subsystem.

Microsoft Windows XP SP3 no valida direcciones en ciertas rutinas del manejador IRP, lo que permite a usuarios locales escribir datos en localizaciones de memoria arbitrarias, y como consecuencia ganar privilegios, a través de una dirección manipulada en una llamada IOCTL, relacionado con (1) el controlador MQAC.sys en el subsistema MQ Access Control y (2) el controlador BthPan.sys en el subsistema Bluetooth Personal Area Networking.
