Critical PHP Vulnerabilities

Hi all, was running Nessus security scanner and it picked up 2 critical vulnerabilities on my EdgeOS router/firewall.  Bascially its saying systems with releases lower than PHP 7.0.12 suffer many significant flaws.  So my question is whether Edge OS 1.9.0 does in fact utilize PHP 7.0.12 and if it does, 1) are the flaws somehow masked by custom protections or 2) is there a beta revision that updates the PHP version to .12 or higher?

Thanks!
