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

Jesse Ruderman and Petko D. Petkov reported that the jar protocol
handler in Mozilla Firefox and Seamonkey does not properly check MIME
types (CVE-2007-5947). Gregory Fleischer reported that the
window.location property can be used to generate a fake HTTP Referer
(CVE-2007-5960). Multiple memory errors have also been reported
(CVE-2007-5959).

Impact
======

A remote attacker could possibly exploit these vulnerabilities to
execute arbitrary code in the context of the browser and conduct
Cross-Site-Scripting or Cross-Site Request Forgery attacks.

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 -v ">=www-client/mozilla-firefox-2.0.0.11"

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

    # emerge --sync
    # emerge --ask -1 -v ">=www-client/mozilla-firefox-bin-2.0.0.11"

All SeaMonkey users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/seamonkey-1.1.7"

All SeaMonkey binary users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot -v ">=www-client/seamonkey-bin-1.1.7"
