JavaScript in the “about:webrtc” page is not sanitized properly being
assigned to “innerHTML”. Data on this page is supplied by WebRTC usage and
is not under third-party control, making this difficult to exploit, but the
vulnerability could possibly be used for a cross-site scripting (XSS)
attack. This vulnerability affects Firefox < 55.
