=====================================================================

1. Summary:

Red Hat OpenShift Container Platform release 3.11.404 is now available with
updates to packages and images that fix several bugs and add enhancements.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat OpenShift Container Platform 3.11 - noarch, ppc64le, x86_64

3. Description:

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.

4. Solution:

3.11.404, for important instructions on how to upgrade your cluster and
fully apply this asynchronous errata update:

Red Hat Network to apply this update are available at

5. Bugs fixed (https://bugzilla.redhat.com/):

1902111 - CVE-2020-27813 golang-github-gorilla-websocket: integer overflow leads to denial of service
1917013 - yum excluders are not set back in nodes after upgrade when it is done in separate phases and "openshift_upgrade_nodes_label" parameter is used to filter which nodes should be upgraded at a time
1933090 - [3.11] Upgrade fails when specifying openshift_upgrade_nodes_label
1934136 - [AWS] The `build_ami.yml` playbook to create the primed image for Cluster Autoscaler is restarting the host.
