NVD Description

Note: Versions mentioned in the description apply only to the upstream lxc-templates package and not the lxc-templates package as distributed by Ubuntu.

In LXC 2.0, many template scripts download code over cleartext HTTP, and omit a digital-signature check, before running it to bootstrap containers.
