The WebRTC subsystem in Mozilla Firefox before 36.0 recognizes turns: and stuns: URIs but accesses the TURN or STUN server without using TLS, which makes it easier for man-in-the-middle attackers to discover credentials by spoofing a server and completing a brute-force attack within a short time window.

Remediation

Check the references section for vendor advisories and patches from canonical. Update ubuntu_linux to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
