Description

The named pipe, \pipe\nsvr, has a NULL DACL allowing any authenticated user to
interact with the service. It contains a stacked based buffer overflow as a result
of a memmove operation. Note the slight spelling differences: the executable is 'nvvsvc.exe',
the service name is 'nvsvc', and the named pipe is 'nsvr'.

This exploit automatically targets nvvsvc.exe versions dated Nov 3 2011, Aug 30 2012, and Dec 1 2012.
It has been tested on Windows 7 64-bit against nvvsvc.exe dated Dec 1 2012.
