A flaw was found in quic-go. This issue may allow an attacker to trigger a denial of service by sending a large number of NEW_CONNECTION_ID frames that retire old connection IDs. The receiver is supposed to respond to each retirement frame with a RETIRE_CONNECTION_ID frame, but the attacker can prevent the receiver from sending out the vast majority of these RETIRE_CONNECTION_ID frames by selectively acknowledging received packets and collapsing the peers congestion window and by manipulating the peer’s RTT estimate.
