Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

A Mozilla Foundation Security Advisory reports :

Two vulnerabilities have been discovered in Firefox, which can be
exploited by malicious people to conduct cross-site scripting attacks
and compromise a user's system.

- The problem is that 'IFRAME' JavaScript URLs are not properly
protected from being executed in context of another URL in the history
list. This can be exploited to execute arbitrary HTML and script code
in a user's browser session in context of an arbitrary site.

- Input passed to the 'IconURL' parameter in
'InstallTrigger.install()' is not properly verified before being used.
This can be exploited to execute arbitrary JavaScript code with
escalated privileges via a specially crafted JavaScript URL.

Successful exploitation requires that the site is allowed to install
software (default sites are 'update.mozilla.org' and
'addons.mozilla.org').

A combination of vulnerability 1 and 2 can be exploited to execute
arbitrary code.
