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"
