Impact Data channel communication was incorrectly allowed with users who have failed DTLS certificate verification.

This attack requires Attacker knows the ICE password. Only take place during PeerConnection handshake.

This attack can be detected by monitoring PeerConnectionState in all versions of Pion WebRTC.

Patches Users should upgrade to v3.0.15.

The exact patch is https://github.com/pion/webrtc/commit/545613dcdeb5dedb01cce94175f40bcbe045df2e

Workarounds Users should listen for when PeerConnectionState changes to PeerConnectionStateFailed. When it enters this state users should not continue using the PeerConnection.

Thank you to https://github.com/Gaukas for discovering this.

webrtc-native uses WebRTC from chromium project. webrtc-native downloads binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested binary with an attacker controlled binary if the attacker is on the network or positioned in between the user and the remote server.

Use-after-free vulnerability in the DesktopDisplayDevice class in the WebRTC implementation in Mozilla Firefox before 45.0 on Windows might allow remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

Multiple race conditions in dom/media/systemservices/CamerasChild.cpp in the WebRTC implementation in Mozilla Firefox before 45.0 on Windows might allow remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.
