Descriptions

In sshd in OpenSSH before 10.0, the DisableForwarding directive does not adhere to the documentation stating that it disables X11 and agent forwarding.

This update for openssh fixes the following issue. Fixed logic error in DisableForwarding option. Fixed ssh client segfault with GSSAPIKeyExchange=yes in ssh_kex2 due to gssapi proposal not being correctly initialized. The problem was introduced in the rebase of the patch for 9.6p1. Enable --with-logind to call the SetTTY dbus method in systemd. This allows "wall" to print messages in ssh ttys.
