1. Problem Summary(From the BugTraq database of securityfocus.com,id#2377)

   As designed, the software makes it possible for a user to remotely
   access network statistics using cgi scripts and HTTP FORM
   methods. When queried, the cgi accesses analog, and outputs
   statistics to a web page. Due to a buffer overflow in analog, and
   improper checking of input by the cgi program, it is possible for a
   user to supply a long ALIAS field to the analog program, which will
   result in a buffer overflow.

2. Impact(Also from the BugTraq database, id#2377)

   A user can remotely execute code and execute commands with privileges
   equal to the httpd process.

3. Solution

   First, uninstall the package analog-form using the command:

   rpm -e analog-form-3.0-1.i386.rpm, or whatever version of analog-form
   you are currently running
     
   Then, update the analog 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/analog-4.16-2.i386.rpm

   The source RPM can be downloaded here:

   ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/analog-4.16-2.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
