GENTOO LINUX SECURITY ANNOUNCEMENT 200302-16
- - ---------------------------------------------------------------------

          PACKAGE : vnc
          SUMMARY : insecure cookie generation
             DATE : 2003-02-24 11:35 UTC
          EXPLOIT : remote
VERSIONS AFFECTED : <3.3.6-r1
    FIXED VERSION : 3.3.6-r1

- - ---------------------------------------------------------------------

- From Red Hat Security Advisory RHSA-2003:041-12:

"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."

SOLUTION

It is recommended that all Gentoo Linux users who are running
