Synopsis
========

New releases of Mozilla, Epiphany, Galeon, Mozilla Thunderbird, and
Mozilla Firefox fix several vulnerabilities, including remote DoS and
buffer overflows.

Background
==========

Mozilla is a popular web browser that includes a mail and newsreader.
Galeon and Epiphany are both web browsers that use gecko, the Mozilla
rendering engine. Mozilla Firefox is the next-generation browser from
the Mozilla project that incorporates advanced features that are yet to
be incorporated into Mozilla. Mozilla Thunderbird is the
next-generation mail client from the Mozilla project.

Description
===========

Mozilla, Galeon, Epiphany, Mozilla Firefox and Mozilla Thunderbird
contain the following vulnerabilities:

* All Mozilla tools use libpng for graphics. This library contains a
  buffer overflow which may lead to arbitrary code execution.

* If a user imports a forged Certificate Authority (CA) certificate,
  it may overwrite and corrupt the valid CA already installed on the
  machine.

Mozilla, Mozilla Firefox, and other gecko-based browsers also contain a
bug in their caching which may allow the SSL icon to remain visible,
even when  the site in question is an insecure site.

Impact
======

Users of Mozilla, Mozilla Firefox, and other gecko-based browsers are
susceptible to SSL certificate spoofing, a Denial of Service against
legitimate SSL sites, crashes, and arbitrary code execution. Users of
Mozilla Thunderbird are susceptible to crashes and arbitrary code
execution via malicious e-mails.

Workaround
==========

There is no known workaround for most of these vulnerabilities. All
users are advised to upgrade to the latest available version.

Resolution
==========

All users should upgrade to the latest stable version:

    # emerge sync

    # emerge -pv your-version
    # emerge your-version
