                    Mandrake Linux Security Update Advisory
    ________________________________________________________________________

    Package name: vnc
    Advisory ID: MDKSA-2003:022
    Date: February 24th, 2003

    Affected versions: 7.2, 8.0, 8.1, 8.2, 9.0
    ________________________________________________________________________

    Problem Description:

     A vulnerability was discovered in the VNC server script that generates
     an X cookie, used by X authentication. The script generated a cookie
     that was not strong enough and allow an attacker to more easily guess
     the authentication cookie, thus obtaining unauthorized access to the
     VNC server.

    of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". A list of
    FTP mirrors can be obtained from:

      http://www.mandrakesecure.net/en/ftp.php

    Please verify the update prior to upgrading to ensure the integrity of
    the downloaded package. You can do this with the command:

      rpm --checksig <filename>

    All packages are signed by MandrakeSoft for security. You can obtain
    the GPG public key of the Mandrake Linux Security Team from:
