All the necessary freedoms are specified here; good.

So long as "display [the notice] in all copies of the software" means
to have the text of the notice in the source code, this is fine.

If it could mean "cause the program to display the notice when
executed", that's a non-free restriction. I don't think such an
interpretation is valid though.

Possibly problematic. If Support Company FooBar sells the software and
offers a warranty, then requiring the user (meaning "recipient of this
work", I suppose) to accept all liability is a non-free restriction.

It would be best if this phrase wasn't in the terms at all, because
the immediately-following disclaimer is perfectly clear without
placing any restrictions.

Fine; the copyright holders are disclaiming any warranty.

Too vague. The user must grant "a royalty-free license" under what
terms? The terms of this license, like the GPL? Any license terms they
choose, like the 3-clause BSD license? Something else? These terms
don't make this clear.

My verdict: It's probably intended to grant the freedoms required for
DFSG-freedom, and mostly does so, with a few vague points. The Debian
ftp-masters would probably consider it good enough.
