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
