Hi Ed.

Understood.   There's "a lot" of FreeBSD based kit out there, running on
32 bit hardware.  A lot of NAS's for one.   (I don’t suppose any of
those commercial "appliances" will ever be updated though.)

But from my understanding, this problem has probably been present since
1995, and maybe even earlier.  There is a paper published somewhere that
documents such issues, dated around 1992!  Awaiting for the SN645 show
notes to be published, for that info.

(Keep an eye on  https://www.grc.com/securitynow.htm )

The conclusion then, was that it was probably not a problem as would be
"too difficult" to manipulate for any gain.

The machines I have, are ex Win'2000 boxes, so are probably affected.  
One of them was web facing.  It's not now!

Best Regards.

Dave B.
