RunC Flaw Lets Attackers Escape Linux Containers to Gain Root on Hosts

Will this issue be addressed in a not too distant future release?

I was told by a dev that Hassio does not include the exec command that is needed to take advantage of this flaw, but it will be patched regardless.

Already fixed in most Ubuntu-based systems using docker and runc.

If you have Unattended Upgrades enabled (the default is Enabled since 16.04), then you likely have the fix already.
