✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Avoid using ssh-agent forwarding to untrusted remote hosts, or disable agent forwarding entirely by removing `ForwardAgent yes` from SSH configuration. If agent forwarding is required, avoid locking the agent while forwarded sessions are active. Workaround: Avoid issuing dynamic remote-forwarding commands over active SSH multiplexing connections, or disable socket multiplexing by setting ControlMaster no in ~/.ssh/config. Workaround: Set PermitTunnel no in /etc/ssh/sshd_config to disable TUN/TAP tunnel forwarding server-wide. Alternatively, restrict tunnel permissions for specific users or groups using Match blocks in sshd_config or explicit no-tun directives in authorized_keys.
