Technical Description

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.

Remediation

Check the references section for vendor advisories and patches from microsoft. Update windows_xp to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
