May be code is different for Windows XP or vulnerability is later in code.We discovered this bug some time ago and were preparing an advisory when it was publicly disclosed. Since the exploit is already public, here's my analysis of the vulnerability: http://www.determina.com/security.research/vulnerabilities/csrss-harderror.html It's a double free bug that leads to arbitrary code execution in the CSRSS process.
