Synopsis

The remote Debian host is missing a security update.

Description

This security upload has been prepared in cooperation of the Debian Kernel, Security and LTS Teams and features the upstream stable release 2.6.32.64 (see https://lkml.org/lkml/2014/11/23/181 for more information for that). It fixes 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 give feedback to [email protected].

If you are not using openvz flavors, please still consider b+c :-)
