Subject: Re: Re: Announce: Portable OpenSSH 7.2p2 released

It should be noted, that the new openSSH 7.2p2 also includes the fix for
CVE-2016-1908 as it had been assigned here:
http://seclists.org/oss-sec/2016/q1/115

* SECURITY: Eliminate the fallback from untrusted X11-forwarding to trusted
forwarding for cases when the X server disables
  the SECURITY extension. Reported by Thomas Hoger.

The associated commit (
https://anongit.mindrot.org/openssh.git/commit/?id=ed4ce82dbfa8a3a3c8ea6fa0db113c71e234416c)
did not make it into the last release as per last-minute decision (see:
http://lists.mindrot.org/pipermail/openssh-unix-dev/2016-January/034684.html
)

Anybody, please correct me if I am wrong
