Upgrade github.com/opencontainers/runc/libcontainer to version 1.0.0-rc7 or higher.

Overview

github.com/opencontainers/runc/libcontainer is a package for a modern container runtime.

Affected versions of this package are vulnerable to Command Injection 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.
