___________________________________________________________________________

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

1. Problem Summary

    Ed creates temp files insecurely.


2. Impact

   It is possible for a local user with malicious intent to carry out a
   symbolic link attack, overwriting or corrupting files created by the
   user running ed.

3. Solution

  Update each 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/ed-0.2-16.i386.rpm

  The source RPM can be downloaded here:

  ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/ed-0.2-16.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
