DESCRIPTION:
A vulnerability has been reported in Microsoft Windows, which can be
exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to an error in the client/server
run-time subsystem when processing specially crafted sequences of
Unicode characters.

Successful exploitation allows execution of arbitrary code with
LocalSystem privileges, but requires that the system is configured
with a Chinese, Japanese, or Korean system locale.

SOLUTION:
Apply patches.
