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
