|
|
This module exploits a kernel based overflow when sending abnormal PPTP Control Data
|
|
packets to Microsoft Windows 2000 SP0-3 and XP SP0-1 based PPTP RAS servers
|
|
(Remote Access Services). Kernel memory is overwritten resulting in a BSOD.
|
|
Code execution may be possible however this module is only a DoS.
