The remote Red Hat host is missing one or more security updates.
Updated VNC packages are available to fix a weak cookie vulnerability.
VNC is a tool for providing a remote graphical user interface.
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.
All users of VNC are advised to upgrade to these erratum packages,
which contain a patch to correct this issue.

Update the affected vnc, vnc-doc and / or vnc-server packages.

Medium / CVSS Base Score : 5.0
