CVE-2014-4971
HighSummary
Microsoft Windows XP SP3 does not validate addresses in certain IRP handler routines, allowing local users to write data to arbitrary memory locations. This can lead to privilege escalation via a crafted address in an IOCTL call, related to the MQAC.sys and BthPan.sys drivers.
Risk Assessment
This vulnerability poses a risk to Windows XP SP3 systems, allowing local users to escalate privileges and potentially take control of the system.
Recommendation
It is recommended to upgrade the system to a newer version of Windows that is not vulnerable to this flaw and to restrict access to the system for unauthorized users.

Original NVD description (English source)
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.
