1. Problem Summary(From the Red Hat, Inc. Security Advisory)

A buffer overflow exists in Netscape's HTML parsing code. By using
specially designed code, a remote website could cause arbitrary code to
be run on the local machine.

2. Solution

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

rpm -Uvh --nodeps --force ftp_path_to_filename

Where ftp_path_to_filename is the following:

netscape-communicator-4.76-5.i386.rpm

The source RPM can be downloaded here:

netscape-communicator-4.76-5.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
