These are the vulnerability I'm referring to and they have been
addressed in OpenSSH versions 6.6 and 7.2p2:
The sshd server fails to validate user-supplied X11 authentication
when establishing an X11 forwarding session. An authenticated user
arbitrary xauth commands by sending an x11 channel request that includes a
newline character in the x11 cookie.
Please note that Systems with X11Forwarding enabled are affected.
OpenSSH versions prior to 7.2p2
you are apparently talking about CVE-2016-3115
see noted at bottom:
[jessie] - openssh <no-dsa> (Minor issue)
[wheezy] - openssh <no-dsa> (Minor issue)
this was apparently resolved as minor, so no DSA was issued.
The security issue is caused by an error within the "child_set_env()"
(usr.bin/ssh/session.c) and can be exploited to bypass intended environment
restrictions by using a substring before a wildcard character.
OpenSSH Versions prior to 6.6 are affected
