NVD Description

Note: Versions mentioned in the description apply only to the upstream pluralsh-agent-harness-0.6 package and not the pluralsh-agent-harness-0.6 package as distributed by Minimos. See How to fix? for Minimos:latest 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.
