DESCRIPTION:
Rubén Santamarta has discovered a vulnerability in Microsoft Windows,
which can be exploited by malicious, local users to gain knowledge of
sensitive information.
The problem is that 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.
SOLUTION:
Allow only trusted users access to the system.
