Synopsis
========

Multiple vulnerabilities have been reported in Mozilla Firefox,
Thunderbird, SeaMonkey and XULRunner, some of which may allow
user-assisted arbitrary remote code execution.

Background
==========

Mozilla Firefox is an open-source web browser from the Mozilla Project,
and Mozilla Thunderbird an email client. The SeaMonkey project is a
community effort to deliver production-quality releases of code derived
from the application formerly known as the 'Mozilla Application Suite'.
XULRunner is a Mozilla runtime package that can be used to bootstrap
XUL+XPCOM applications like Firefox and Thunderbird.

Description
===========

Mozilla developers fixed several bugs, including an issue with
modifying XPCNativeWrappers (CVE-2007-3738), a problem with event
handlers executing elements outside of the document (CVE-2007-3737),
and a cross-site scripting (XSS) vulnerability (CVE-2007-3736). They
also fixed a problem with promiscuous IFRAME access (CVE-2007-3089) and
an XULRunner URL spoofing issue with the wyciwyg:// URI and HTTP 302
redirects (CVE-2007-3656). Denials of Service involving corrupted
memory were fixed in the browser engine (CVE-2007-3734) and the
JavaScript engine (CVE-2007-3735). Finally, another XSS vulnerability
caused by a regression in the CVE-2007-3089 patch was fixed
(CVE-2007-3844).

Impact
======

A remote attacker could entice a user to view a specially crafted web
page that will trigger one of the vulnerabilities, possibly leading to
the execution of arbitrary code or a Denial of Service. It is also
possible for an attacker to perform cross-site scripting attacks, which
could result in the exposure of sensitive information such as login
credentials.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Mozilla Firefox users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-2.0.0.6"

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

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/mozilla-firefox-bin-2.0.0.6"

All Mozilla Thunderbird users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-2.0.0.6"

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

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-client/mozilla-thunderbird-bin-2.0.0.6"

All SeaMonkey users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/seamonkey-1.1.4"

All SeaMonkey binary users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/seamonkey-bin-1.1.4"

All XULRunner users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-libs/xulrunner-1.8.1.6"
