                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:

 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.

To upgrade automatically, use MandrakeUpdate.  The verification of md5
checksums and GPG signatures is performed automatically for you.

If you want to upgrade manually, download the updated package from one
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:

  https://www.mandrakesecure.net/RPM-GPG-KEYS

Please be aware that sometimes it takes the mirrors a few hours to
update.
