Synopsis

The remote Red Hat host is missing a security update for OpenShift Container Platform 3.11.404.

Description

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2021:0833 advisory.

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments.

This advisory contains the RPM packages for Red Hat OpenShift Container Platform 3.11.404. See the following advisory for the container images for this release:

https://access.redhat.com/errata/RHBA-2021:0832

This release fixes the following bugs:

* Previously, node upgrade playbooks scoped all nodes instead of just the nodes that are filtered by the `openshift_upgrade_nodes_label`. As a result, nodes that were not intended to be upgraded had yum excluders disabled but not reenabled. With this release, the initialization of the variable for filtering nodes to upgrade is moved to earlier in the play, and preconfiguration is scoped to the filtered list of nodes. As a result, only the nodes that are intended for upgrade have yum excluders disabled. (BZ#1917013)

* Previously, node-based facts, such as `l_kubelet_node_name`, were set late in the upgrade cycle, causing the fact to be undefined when referenced. With this release, node-based fact initialization happens earlier in the upgrade cycle so that facts are set prior to being referenced. (BZ#1933090)

* Previously, a bug fix in Ansible 2.9.10 changed the behavior of `delegate_to` for plays using `connection: local` with `hosts: localhost`. This change caused tasks that are intended for remote hosts to be executed locally. With this release, `connection: local` is removed for the affected play, and tasks intended for remote hosts are executed on the remote host. (BZ#1934136)

Security Fix(es):

* golang-github-gorilla-websocket: integer overflow leads to denial of service (CVE-2020-27813)

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.

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 OpenShift Container Platform 3.11.404 package based on the guidance in RHSA-2021:0833.
