Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

It was discovered that CVE-2011-3004, which addressed possible
privilege escalation in addons, also affected Firefox 3.6. An attacker
could potentially exploit Firefox when an add-on was installed that
used loadSubscript in vulnerable ways. (CVE-2011-3647)

Yosuke Hasegawa discovered that the Mozilla browser engine mishandled
invalid sequences in the Shift-JIS encoding. A malicious website could
possibly use this flaw this to steal data or inject malicious scripts
into web content. (CVE-2011-3648)

Marc Schoenefeld discovered that using Firebug to profile a JavaScript
file with many functions would cause Firefox to crash. An attacker
might be able to exploit this without using the debugging APIs which
would potentially allow an attacker to remotely crash the browser.
(CVE-2011-3650).

Solution :

Update the affected firefox and / or xulrunner-1.9.2 packages.
