DEBIAN-CVE-2026-56855

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 connectio...

EUVD-2026-70266

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,...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop via the SSHMSGCHANNELOPEN process. An attacker can cause the system to enter an infinite loop and exhaust CPU resources by advertising a zero maximum packet size during channel establishment. Remediation A fix was pushed...
