概要

Impact

A DTLS Client could provide a Certificate that it doesn't posses the private key for and Pion DTLS wouldn't reject it.

This issue affects users that are using Client certificates only. The connection itself is still secure. The Certificate provided by clients can't be trusted when using a Pion DTLS server prior to v2.1.5

Patches

Upgrade to Pion DTLS v2.1.5

Workarounds

No workarounds available, upgrade to Pion DTLS v2.1.5
