Gatekeeper v3.17.2

Gatekeeper v3.17.2

Gatekeeper is a validating webhook with auditing capabilities that can
enforce custom resource definition-based policies that are run with the
Open Policy Agent (OPA). Gatekeeper is supported through a Red Hat Advanced
Cluster Management for Kubernetes subscription.

Starting in v3.17, users can specify a `containerArguments` list of names
and values for both the audit and webhook configurations to be passed to
the respective deployment. These will be ignored if the argument has
already been set by the operator or specifies an argument listed in the
deny list.

Starting in v3.15, the following namespaces are exempt from admission
control:

* kube-*
* multicluster-engine
* hypershift
* hive
* rhacs-operator
* open-cluster-*
* openshift-*

To disable the default exempt namespaces, set the namespaces you want on
the object.

Security fix(es):

* golang.org/x/oauth2: Unexpected memory consumption during token parsing in
golang.org/x/oauth2 (CVE-2025-22868)
* golang.org/x/crypto/ssh: Denial of Service in the Key Exchange of
