Описание

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.

Воздействие

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.

Обход

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

Решение

All users should upgrade to the latest stable version:

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