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-2019:0487 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):

* docker: Memory exhaustion via large integer used with --cpuset-mems or --cpuset-cpus (CVE-2018-20699)

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.

Bug Fix(es):

* docker runc 'panic: runtime error: invalid memory address or nil pointer dereference' (BZ#1556901)

* temp files in /var/lib/docker persist (BZ#1645591)

* Docker needs to support PIDs Limit for all containers created. (BZ#1660876)

* dockerd may leak memory resources if uncompressing a layer fails (BZ#1661443)

* Docker may not properly close hijacked streams (BZ#1668042)

* Director deployed OCP 3.11 deployment fails with openshift-ansible getting stuck when restarting docker service on master nodes (BZ#1671861)

* Docker service hang (BZ#1678096)

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.
