Please update the package in your installation as soon as possible.
___________________________________________________________________________

1. Problem Summary

   CORE ST reports that an exploit has been found for a bug in the wu-ftpd
  glob code. This is the code that handles filename wild card expansion.

2. Impact

   Any logged in user (including anonymous FTP users) can exploit the bug to
  gain root privileges on the server.

3. Solution

  This has been  corrected in version  wu-ftpd-2.6.1-10

  Update the package from our ftp server by running the following command:

  rpm -Uvh ftp://ftp.turbolinux.com/pub/updates/6.0/security/<rpm>

  Where <rpm> are the following:

  wu-ftpd-2.6.1-10.i386.rpm

  The source RPM can be downloaded from:

  ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/wu-ftpd-2.6.1-10.src.rpm

  **Note: You must rebuild and install the RPM if you choose to download
 and install the SRPM.  Simply installing the SRPM alone WILL NOT CLOSE
 THE SECURITY HOLE.

 Please verify the MD5 checksums of the updates before you install:

  MD5 sum                               Package Name
