|
This module triggers a stack overflow in the Windows Plug
|
|
and Play service. This vulnerability can be exploited on
|
|
Windows 2000 without a valid user account. Since the PnP
|
|
service runs inside the service.exe process, this module
|
|
will result in a forced reboot on Windows 2000. Obtaining
|
|
code execution is possible if user-controlled memory can
|
|
be placed at 0x00000030, 0x0030005C, or 0x005C005C.
