OpenSSH 6.8 and 6.9 incorrectly set TTYs to be world-writable.
Local attackers may be able to write arbitrary messages to
logged-in users, including terminal escape sequences. Reported
by Nikolay Edigaryev.
Fixed a privilege separation
weakness related to PAM support. Attackers who could successfully
compromise the pre-authentication process for remote code
execution and who had valid credentials on the host could
impersonate other users.
Fixed a use-after-free bug
related to PAM support that was reachable by attackers who could
compromise the pre-authentication process for remote code
execution.
