_____________________________________________________________________________________________

A security hole was discovered in the package mentioned above. Please
update the package in your installation as soon as possible.
_____________________________________________________________________________________________

1. Problem Summary

   Dialog creates lock-files insecurely, which makes it vulnerable
   to a symlink attack.


2. 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/dialog-0.9a-2.i386.rpm

   The source RPM can be downloaded here:

   ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/dialog-0.9a-2.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
- ---------------------------------------------------------------------------------------------
