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:
