Synopsis
=======
Several vulnerabilities in the Mozilla Suite and Firefox allow an
attacker to conduct cross-site scripting attacks or to execute
arbitrary code.

Background
=========
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.

Affected packages
================
    -------------------------------------------------------------------
     Package                         /  Vulnerable  /       Unaffected
    -------------------------------------------------------------------
  1  www-client/mozilla-firefox           < 1.0.4             >= 1.0.4
  2  www-client/mozilla-firefox-bin       < 1.0.4             >= 1.0.4
  3  www-client/mozilla                   < 1.7.8             >= 1.7.8
  4  www-client/mozilla-bin               < 1.7.8             >= 1.7.8
    -------------------------------------------------------------------
     4 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
==========
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).

Impact
=====
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.

Workaround
=========
Affected systems can be protected by disabling JavaScript. However, we
encourage Mozilla Suite or Mozilla Firefox users to upgrade to the
latest available version.

Resolution
=========
All Mozilla Firefox users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-1.0.4"

All Mozilla Firefox binary users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose 
">=www-client/mozilla-firefox-bin-1.0.4"

All Mozilla Suite users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-1.7.8"

All Mozilla Suite binary users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-bin-1.7.8"
