RHSA-2003-068: vnc Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the vnc packages
Detailed Explanation for this Vulnerability Test
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.
