Security and LTS Teams and features the upstream stable release 2.6.32.64 (see

the CVEs described below.

Note: if you are using the openvz flavors, please consider three things: a.) 
we haven't got any feedback on them (while we have for all other flavors) b.) 
so do your test before deploying them and c.) once you have done so, please
