Description Mark J. Cox 2003-02-19 14:05:45 UTC 
The VNC server acts as an X server, but the script for starting it
generates an MIT X cookie (which is used for X authentication) without
using a strong enough random number generator. This could allow an
attacker to be able to more easily guess the authentication cookie.
