it appears the bsdi version of su uses kerbose tickets if kerbose is

Yes, but the BSDI kerberosIV implementation does not appear to
have the problem (the tf_init() routine which opens the ticket
file checks to see that the real uid of the process is either
root or owns the ticket file).

Similarly, my tests on FreeBSD 2.2.2-RELEASE (and above) indicate that the
system is not vulnerable.
