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

|

"The VNC server acts as an X server, but the script for starting it |
20 |
generates an MIT X cookie (which is used for X authentication) without |
21 |
using a strong enough random number generator. This could allow an |
22 |
attacker to be able to more easily guess the authentication cookie." |
