github.com/quic-go/quic-go is vulnerable to a Connection ID exhaustion. The vulnerability is caused by an attacker manipulating of the round-trip time (RTT) estimate of the peer by sending a large number of NEW_CONNECTION_ID frames to exhaust the memory of the receiver, which allows an attacker to prevent RETIRE_CONNECTION_ID frame responses.
