___________________________________________________________________________

A security hole has been discovered in the package gtk+.  Please update
this package in your installation as soon as possible.
___________________________________________________________________________

1. Problem Summary
   
       The environment variable GTK_MODULES allows a local user to enter a 
   directory path to a module that may not be associated with the GTK+ tool-
   kit.  Hence, an attacker can create a custom module and load it using 
   the toolkit.

2. Impact

       An attacker can elevate his privileges, overwrite system files and 
   execute potentially harmful code.
   
  
3. Solution

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

      rpm -Uvh ftp_path_to_filename

  Where ftp_path_to_filename is the following:

ftp://ftp.turbolinux.com/pub/updates/6.0/security/gtk+-1.2.8-10.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/gtk+-devel-1.2.8-10.i386.rpm

  The source RPM can be downloaded here:

ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/gtk+-1.2.8-10.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.

          In order to rebuild the gtk+ binaries from the SRPM, be sure
  you have XFree86-devel, glib(v1.2.8 or greater), and glib-devel(v1.2.8
  or greater) installed on your system.

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

  MD5 sum                               Package Name
