docker: insecure opening of file-descriptor allows privilege escalation

The runc component used by docker exec feature of docker allowed additional container processes to be ptraced by the pid 1 of the container. This allows the main processes of the container, if running as root, to gain low-level access to these new processes during initialization. An attacker can,...
