Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the QUIC server when address validation is disabled. An attacker can crash the server by sending an initial packet with an invalid or expired token. Address validation is enabled by default, so this is reachable only when SSL_LISTENER_FLAG_NO_VALIDATE is passed to SSL_new_listener().
