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

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.
