Prevent DoS on deadlocked established channel in golang.org/x/crypto/ssh

v0.1.0 - v0.55.0

Summary

Prevent DoS on deadlocked established channel in golang.org/x/crypto/ssh

Details

Previously, after a channel has been established, a malicious peer could send crafted messages that would deadlock the entire connection.

Now, we handle all RFC 4254 channel messages; global requests are handled explicitly. Then, treat all other messages as a protocol error and tear the connection down instead of buffering and blocking.
