high Nessus Plugin ID 127073

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

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.
(CVE-2018-15664)

Solution

Run 'yum update docker' to update your system.
