Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to unbounded allocation of pending connections in port_default_packet_handler. An attacker can exhaust memory and make the QUIC listener unavailable by sending many valid QUIC Initial packets with unknown destination connection IDs faster than the application calls SSL_accept_connection() to accept them.
