| summary: Improper validation of client certificates in github.com/pion/dtls/v2 |
| description: |- |
| Client-provided certificates are not correctly validated, and must not be |
| trusted. |
| |
| DTLS client certificates must be accompanied by proof that the client possesses |
| the private key for the certificate. The Pion DTLS server accepted client |
| certificates unaccompanied by this proof, permitting an attacker to present any |
| certificate and have it accepted as valid. |
