Synopsis

The remote Red Hat host is missing a security update for docker.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:2634 advisory.

Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.

Security Fix(es):

* It was found that Docker would launch containers under the specified UID instead of a username. An attacker able to launch a container could use this flaw to escalate their privileges to root within the launched container. (CVE-2016-3697)

This issue was discovered by Mrunal Patel (Red Hat).

Bug Fix(es):

* This update also provides various bug fixes and enhancements. Users are advised to upgrade to these updated packages.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
