openssh/openssh-7.7p1-X11_trusted_forwarding.patch
Antonio Larrosa 45f6d17800 - Add obsoletes for openssh-server-config-rootlogin since that
package existed for a brief period of time during SLE 15 SP6/
  Leap 15.6 development but even if it was removed from the
  repositories before GM, some users might have it in their
  systems from having tried a beta/RC release (boo#1227350).

    quoting was present in the user-supplied ssh_config(5) directive
    (bsc#1218215, CVE-2023-51385).

# enable trusted X11 forwarding by default in both sshd and sshsystem-wide
# configuration
# bnc#50836 (was suse #35836)
Enable Trusted X11 forwarding by default, since the security benefits of
having it disabled are negligible these days with XI2 being widely used.
