There is no fixed version for Debian:8 lxc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream lxc package and not the lxc package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.
