Image update to include Debian hardening against meltdown/spectre attacks

[muellermichel]

Would it be possible to get an ETA on that kernel update? According to the debian tracker we need kernel version 3.16.51-3+deb8u1 . Thank you in advance for any feedback!

I think I can close this - Docker containers seem to fully inherit the vulnerabilities from host system, so the container image itself should not influence this.
