&gt; We were unable to identify this backdoor in versions 6.2.0r15, 6.2.0r16, 6.2.0r18 and it is probably safe to say that the entire 6.2.0 series was not affected<p>this sounds fishy, like Juniper trying to push users to upgrade from _non affected_ builds to a new firmware with a fresh set of NSA backdoors.
