This one was fixed a month ago after your last advisory. Obviously, if
you're still using the same version of the OS you used in your initial
advisory, it's not going to be fixed :-)

This one is a hole in the vendor-provided software, which wants to install
it setuid uucp by default. With ~2800 third-party apps shipped with
FreeBSD, we can't be held responsible for the security of all of them :-)

This one is our fault (in the sense that installing it setgid games so it
can write a high score file is not something the software does by
default).

Your advisory wasn't clear whether or not you contacted the port
maintainers directly about these, and they were just slow off the mark, or
if it was just security-officerfreebsd.org. Assuming the former, one way
of expediting the process would be to send mail to the (new)
auditfreebsd.org mailing list which has several people who will be quite
happy to do some butt-kicking to get a response :-)
