A flaw was discovered in the API endpoint behind the ‘docker cp’ command. The endpoint is vulnerable to a Time Of Check to Time Of Use (TOCTOU) vulnerability in the way it handles symbolic links inside a container. An attacker who has compromised an existing container can cause arbitrary files on the host filesystem to be read/written when an administrator tries to copy a file from/to the container.
Stopping a container prior to running "docker cp" removes the TOCTOU vulnerability.
