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.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
