Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
