Arbitrary code can be executed on the remote host through the web browser.


The remote host is running a version of Windows containing a bug in the CSRSS error message handling routine that could allow an attacker to execute arbitrary code on the remote host by luring a user on the remote host into visiting a rogue website.

Additionally, the system is prone to the following types of attack :

- Local Privilege Elevation

- Denial of Service (Local)


Microsoft has released a set of patches for Windows 2000, XP, 2003 and Vista.
