Vulnerability in Docker (CVE-2016-9962)

Summary

Vulnerability in Docker (CVE-2016-9962). Successful exploitation can lead to full system takeover.

Original description

The description as published by the source.

RunC allowed additional container processes via 'runc exec' to be ptraced by the pid 1 of the container. This allows the main processes of the container, if running as root, to gain access to file-descriptors of these new processes during the initialization and can lead to container escapes or modification of runC state before the process is fully placed inside the container.
