The Mozilla Suite is a popular all-in-one web browser that
includes a mail and news reader. Mozilla Firefox is the next-generation
browser from the Mozilla project.

<p>
The Mozilla Suite and Firefox do not properly protect "IFRAME"
JavaScript URLs from being executed in context of another URL in the
history list (CAN-2005-1476). The Mozilla Suite and Firefox also fail
to verify the "IconURL" parameter of the "InstallTrigger.install()"
function (CAN-2005-1477). Michael Krax and Georgi Guninski discovered
that it is possible to bypass JavaScript-injection security checks by
wrapping the javascript: URL within the view-source: or jar:
pseudo-protocols (MFSA2005-43).
</p>
</description>
<impact type="normal">
<p>
A malicious remote attacker could use the "IFRAME" issue to
execute arbitrary JavaScript code within the context of another
website, allowing to steal cookies or other sensitive data. By
supplying a javascript: URL as the "IconURL" parameter of the
"InstallTrigger.Install()" function, a remote attacker could also
execute arbitrary JavaScript code. Combining both vulnerabilities with
a website which is allowed to install software or wrapping javascript:
URLs within the view-source: or jar: pseudo-protocols could possibly
lead to the execution of arbitrary code with user privileges.
</p>
</impact>
<workaround>
<p>
Affected systems can be protected by disabling JavaScript.
However, we encourage Mozilla Suite or Mozilla Firefox users to upgrade
to the latest available version.
</p>
</workaround>
<resolution>
<p>
All Mozilla Firefox users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/mozilla-firefox-1.0.4&quot;</code>
<p>
All Mozilla Firefox binary users should upgrade to the latest
version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/mozilla-firefox-bin-1.0.4&quot;</code>
<p>
All Mozilla Suite users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/mozilla-1.7.8&quot;</code>
<p>
All Mozilla Suite binary users should upgrade to the latest
version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/mozilla-bin-1.7.8&quot;</code>
