A security hole has been discovered in the dhcp packages.  Please update
the packages in your installation as soon as possible.

1. Problem Summary

   It is possible for a user to gain root access to a system through the
   use of clever shell metacharacter hacks.


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/dhcp-2.0pl5-2.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/dhcp-client-2.0pl5-2.i386.rpm

   The source RPM can be downloaded here:

   ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/dhcp-2.0pl5-2.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
--------------------------------------------------------------------------------------------

  f8979df299dfbe4f5d6edca681edd8bf      dhcp-2.0pl5-2.i386.rpm
  48bc3d9afa77a73660aebc8905a8696f      dhcp-client-2.0pl5-2.i386.rpm
