1. Topic:

New Netscape packages are available that fix a buffer overflow
in parsing HTML.

It is recommended that all Netscape users update to the fixed
packages.

2000-11-27: Added packages for Red Hat Linux 7 for Alpha

Red Hat Linux 6.0 - i386, alpha, sparc
Red Hat Linux 6.1 - i386, alpha, sparc
Red Hat Linux 6.2 - i386, alpha, sparc

3. Problem description:

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.

4. Solution:

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.

5. Bug IDs fixed  ( for more info):
