[BlueOnyx:20177] EL5/6/7 Kernel vulnerability

[Michael Stauber]

Hi all,

This is a bit of a rare bird that we haven't seen in a while. A nifty
kernel vulnerability that allows a privilege escalation.

See: https://access.redhat.com/security/cve/CVE-2016-5195

The OpenVZ kernelw on Aventurin{e} are also affected.

At this time there is a procedure available that allows to build a
kernel module that mitigates against this attack vector:

https://bugzilla.redhat.com/show_bug.cgi?id=1384344#c13

But it's not entirely trivial. Updated kernel should be available soon
from upstream.
