Description Ed McKenzie 2001-08-17 21:08:29 UTC 
The medium security level in lokkit blocks the X11 ports on 6000:6009, but
it doesn't block VNC ports on 5800:5809 and 5900:5909.  I'd hope it would,
since a.) VNC is essentially a cleartext protocol, and b.) one can do more
damage via VNC than via an unprotected X port.

We (Red Hat) should really try to fix this before next release.
