1. Problem Summary

   There is a serious problem in netscape's java libraries that allows
   an applet to act as a web server on the client machine, exposing
   all files on the machine to the world.

   The exploit of this vulnerability is widely published under the
   name "Brown Orifice".

   This update also contains fixes a buffer overrun condition while
   processing JPEG files.  This bug could also be exploited by 
   malicious web servers to obtain access to the client machine.

2. Impact

   It is possible for the browser to act as a web server for the
   client's entire machine and can also allow access into the client
   machine via a buffer overrun condition.

3. Solution

  Update the package from our ftp server by running the following
  command for then package:

  rpm -Uvh --nodeps --Force ftp_path_to_filename

  Where ftp_path_to_filename is the following:

ftp://ftp.turbolinux.com/pub/updates/6.0/security/netscape-communicator-4.75-1.i386.rpm

  The source RPM can be downloaded here:

  **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.
