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
