Vulnerability Assessment Summary
Check for the version of the vnc packages

Detailed Explanation for this Vulnerability Assessment

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 permit 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.
