An important set of stable kernel updates

The4.8.3,4.7.9,and 4.4.26 stable kernel updates have beenreleased. There's nothing in the announcements to indicate this, but theyall contain a fix for CVE-2016-5195, a bug that can allow local attackersto overwrite files they should not have write access to. So the "all usersmust upgrade" message seems more than usually applicable this time around.
