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 security updates, and container upgrades.

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.

Note: Gatekeeper support from the Red Hat support team is limited cases
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/.

Security updates:

• golang.org/x/crypto: empty plaintext packet causes panic (CVE-2021-43565)
• golang: crypto/elliptic IsOnCurve returns true for invalid field elements (CVE-2022-23806)

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

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’.
