3. Problem description:

Mozilla Firefox is an open source Web browser.

A cross-site scripting flaw was found in the way Firefox handled the
jar: URI scheme. It was possible for a malicious website to leverage this
flaw and conduct a cross-site scripting attack against a user running
Firefox. (CVE-2007-5947)

Several flaws were found in the way Firefox processed certain malformed web
content. A webpage containing malicious content could cause Firefox to
crash, or potentially execute arbitrary code as the user running Firefox.
(CVE-2007-5959)

A race condition existed when Firefox set the "window.location" property
for a webpage. This flaw could allow a webpage to set an arbitrary Referer
header, which may lead to a Cross-site Request Forgery (CSRF) attack
against websites that rely only on the Referer header for protection.
(CVE-2007-5960)

Users of Firefox are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
