rpcbind "plays" role of portmapper on Solaris 2.X, and there is a secure
version of it, ftp.win.tue.nl:/pub/security, rpcbind on Solaris 2.X
also allows you to steal filehandes; mount daemon doesn't do reserved 
port checking, and once a directory is exported to the host itself
you can steal the filehandle.

I don't know of any security problem in IRIX 4.X portmapper, perhaps in 5.2?
