				This module exploits a stack buffer overflow in the iMatix Corporation
				Xitami Web Server. If a malicious user sends an	If-Modified-Since
				header containing an overly long string, it may be possible to
				execute a payload remotely. Due to size constraints, this module uses
				the Egghunter technique.
