RHEL 7 : docker (RHSA-2019:1910)

high Nessus Plugin ID 127627

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-2019:1910 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: symlink-exchange race attacks in docker cp (CVE-2018-15664)

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):

* slowness of system shutdown when containers are being stopped - dockerd is unable to communicate with rhel-push-plugin (BZ#1714032)

* journald Log() in dockerd causes nil pointer dereference when PutMessage() is called before reading msg.Source (BZ#1720363)

* regression: docker cp: Rel: can't make /..../a relative to a (BZ#1723491)

* Regression: docker cp: can no longer pull image files (BZ#1727488)

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-2019:1910.
