Description: Rubén Santamarta has discovered a vulnerability in Microsoft Windows, which can be exploited by malicious, local users to cause a DoS (Denial of Service) or gain knowledge of sensitive information. The problem is that the Client/Server Run-time Subsystem (CSRSS.exe) does not properly validate arguments passed via NtRaiseHardError and can be exploited to view the contents of CSRSS process memory. The vulnerability is confirmed on a fully-patched Windows XP SP2 system and reportedly affects Windows 2000 SP4 as well. Other versions may also be affected. Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, using the Network Software Inspector. Solution: Apply patches.
