1. Summary:

Gatekeeper Operator v0.2 security updates

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. Description:

Gatekeeper Operator v0.2

Gatekeeper is an open source project that applies the OPA Constraint
Framework to enforce policies on your Kubernetes clusters. 

This advisory contains the container images for Gatekeeper that include bug
fixes and container upgrades. 

Note: Gatekeeper support from the Red Hat support team is limited to where
it is integrated and used with Red Hat Advanced Cluster Management
for Kubernetes. For support options for any other use, see the Gatekeeper
open source project website at:
https://open-policy-agent.github.io/gatekeeper/website/docs/howto/.

* CVE-2022-32148 golang: net/http/httputil: NewSingleHostReverseProxy -
omit X-Forwarded-For not working

3. Solution:

The requirements to apply the upgraded images are different whether or not
you
used the operator. Complete the following steps, depending on your
installation:

* Upgrade gatekeeper operator:
The gatekeeper operator that is installed by the gatekeeper operator policy
has
`installPlanApproval` set to `Automatic`. This setting means the operator
will
be upgraded automatically when there is a new version of the operator. No
further action is required for upgrade. If you changed the setting for
`installPlanApproval` to `manual`, then you must view each cluster to
manually
approve the upgrade to the operator.

* Upgrade gatekeeper without the operator:
The gatekeeper version is specified as part of the Gatekeeper CR in the
gatekeeper operator policy. To upgrade the gatekeeper version:
a) Determine the latest version of gatekeeper by visiting:
https://catalog.redhat.com/software/containers/rhacm2/gatekeeper-rhel8/5fadb4a18d9a79d2f438a5d9.
b) Click the tag dropdown, and find the latest static tag. An example tag
is
'v3.3.0-1'.
c) Edit the gatekeeper operator policy and update the image tag to use the
latest static tag. For example, you might change this line to image:
'registry.redhat.io/rhacm2/gatekeeper-rhel8:v3.3.0-1'.

Refer to https://open-policy-agent.github.io/gatekeeper/website/docs/howto/
for additional information.
