Language:

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-2019:0304 advisory.

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

Security Fix(es):

* A flaw was found in the way runc handled system file descriptors when running containers. A malicious container could use this flaw to overwrite contents of the runc binary and consequently run arbitrary commands on the container host system. (CVE-2019-5736)

Additional details about this flaw, including mitigation information, can be found in the vulnerability article linked from the Reference section.

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

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.

Solution

Update the RHEL docker package based on the guidance in RHSA-2019:0304.
