CVE-2017-1000364 kernel fix brake user-space programs

[Nrbrtx]

Dear Ubuntu developers!

I can't understand how this happen, but your latest kernel upgrade broke
many user-space applications.

For me this process was started from Scilab. I can't use it with new
kernels (linux-image-3.13.0-121-generic on 14.04; linux-image-4.4.0-81-generic
on 16.04).
So I reported bug to launchpad - https://bugs.launchpad.net/bugs/1699892 .

Scilab users ask their developers for the fix, but the root of the problem
is the kernel (see http://bugzilla.scilab.org/show_bug.cgi?id=15141,
http://bugzilla.scilab.org/show_bug.cgi?id=15145,
http://bugzilla.scilab.org/show_bug.cgi?id=15192,http://bugzilla.scilab.org/show_bug.cgi?id=15194,
http://bugzilla.scilab.org/show_bug.cgi?id=15195).

After some digging I discovered that other apps are affected too - see
comments on other bug page ( https://bugs.launchpad.net/bugs/1698919 ). The
list contain the following programs:
* Oracle Java Plugin (see https://bugs.launchpad.net/bugs/1699772 )
* Scilab at least in Trusty and Xenial (see
https://bugs.launchpad.net/bugs/1699892 )
* LPCxpresso (see https://community.nxp.com/thread/453939 )
* RMongo (see https://stackoverflow.com/a/44699417 )
* Ubiquity UniFi (see
https://community.ubnt.com/t5/UniFi-Wireless/UniFi-Controller-failed-after-dist-upgrade/td-p/1967779
)
* Eclipse (see
https://askubuntu.com/questions/927746/eclipse-crashes-with-linux-kernel-4-4-0-81-generic
)

Debian 7, 8 and 9 are affected too (see
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865549 and
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865672 ).

It is not OK.
Do you plan to revert this security patch?
Problem may have wider spread, than detected now.

With best regards,
Norbert.
