Descriptions

Pion WebRTC before 3.0.15 didn't properly tear down the DTLS Connection when certificate verification failed. The PeerConnectionState was set to failed, but a user could ignore that and continue to use the PeerConnection. )A WebRTC implementation shouldn't allow the user to continue if verification has failed.)

Pion WebRTC versiones anteriores a 3.0.15, no eliminó apropiadamente la conexión DTLS cuando falló una comprobación del certificado. El PeerConnectionState se configuró para un fallo, pero un usuario podría ignorarlo y continuar usando PeerConnection. (Una implementación de WebRTC no debería permitir al usuario continuar si la comprobación ha fallado)
