NVD Description

Note: Versions mentioned in the description apply only to the upstream goreleaser package and not the goreleaser package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an atomic established state, set when a channel becomes usable. Until such a time, handlePacket drops every packet other than the open confirmation/failure, without blocking and without tearing down the connection.
