Red Hat, Inc. Security Advisory

Synopsis: New Netscape packages available
Advisory ID: RHSA-2000:109-04
Issue date: 2000-11-17
Updated on: 2000-11-17
Product: Red Hat Linux
Keywords: netscape HTML buffer overflow
Cross references: N/A
---------------------------------------------------------------------

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.

2. Relevant releases/architectures:

Red Hat Linux 6.0 - i386, alpha, sparc
Red Hat Linux 6.1 - i386, alpha, sparc
Red Hat Linux 6.2 - i386, alpha, sparc
Red Hat Linux 7.0 - i386

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 (http://bugzilla.redhat.com/bugzilla for more info):

20415 - Netscape segfault - cured in 4.76
20462 - Netscape 4.75 buffer overflow
