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

Several vulnerabilities were found in Mozilla and Mozilla Firefox:

* Both browsers 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.

* An attacker may force the browser to execute arbitrary code from a
  malicious website by utilizing Mozilla's predictable cache file
  locations, and its ability to execute local files within the local
  zone.

Mozilla, 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.

Impact
======

Users of Mozilla and Mozilla Firefox 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
