___________________________________________________________________________________________

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

1. Problem Summary

   Current and previous version of cvsweb allow remote users to
   access/write files as the default web user via the cvsweb.cgi script.

2. Impact

   Remote read/write access to arbitrary files owned by the default web
   user is possible via this exploit.


3. Solution
     
   Update the packages 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/cvsweb-1.93-1.noarch.rpm


   The source RPM can be downloaded here:

   ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/cvsweb-1.93-1.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
