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"
