Synopsis

The remote Red Hat host is missing one or more security updates for docker.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1234 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):

* runc: AppArmor/SELinux bypass with malicious image that specifies a volume at /proc (CVE-2019-16884)

* proglottis/gpgme: Use-after-free in GPGME bindings during container image pull (CVE-2020-8945)

* containers/image: Container images read entire image manifest into memory (CVE-2020-1702)

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):

* Whitelist statx(2) in docker (BZ#1784228)

* Upgrading docker resulting into increase Systemd logs (BZ#1791870)

* docker should be linked against gpgme-pthread (BZ#1792243)

* docker cannot be updated to 108 on rhos13 as a container fails to start with pivot_root invalid argument error. (BZ#1795376)

* OVS pods are unable to stop when running under docker version 1.13.1-108 (BZ#1796451)

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

Note that Nessus has not tested for these issues 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-2020:1234.
