Windows CSRSS "SrvGetConsoleTitle()" Type Casting Weakness

The following has been copied/pasted from http://secunia.com/advisories/45475/ :

Description

A [non-critical] weakness [has been reported] in Microsoft Windows, which can be exploited by malicious, local users to disclose potentially sensitive information or cause a DoS (Denial of Service).

The weakness is caused due to a type casting error in the "SrvGetConsoleTitle()" function (winsrv.dll) within the Client/Server Run-time Subsystem (CSRSS) when performing a certain size check. This can be exploited to disclose some CSRSS memory or dereference invalid memory causing the kernel to crash.

Solution
[UNpatched:]  Restrict access to trusted users only.
