A while back someone discovered a bug prior to OpenSSH v6.9 relating to =
use of the "-X" option (X11 forwarding) option for the SSH client.  The =
CVE entry contains links to a couple other sites:

	https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2015-5352


The OpenSSH v6.9 release notes (http://www.openssh.com/txt/release-6.9) =
mention this as a security bugfix, but don't indicate if the problem =
existed in versions earlier than v6.8; FreeBSD 9.3-RELEASE, =
10.1-RELEASE, and 10.2-RELEASE appear to have v6.6.1 (although linked =
against different versions of OpenSSL).  I've searched FreeBSD's =
security advisories, but see no mention of this bug at all (certainly =
not in the most recent OpenSSH advisories).  Top search hits in Google =
for this CVE show a couple Linux distros (RedHat and Ubuntu) mention it. =
 For what it's worth, RedHat's declining to fix it in RHEL 5, deferring =
the fix in RHEL 6, and says RHEL 7 is not affected.  Ubuntu's support =
mentions it but describes no plans to fix it.

Are any of you aware of a patch for this that's been committed =
unannounced?  It strikes me as a somewhat esoteric bug, but I promised =
someone I'd ask around about it.  If no patch is committed, is the plan =
to just defer this one until later?
