====================================================================
1. Summary:

Updated images are now available for Red Hat Advanced Cluster Security
(RHACS). The updated image includes new features and bug fixes.

Red Hat Product Security has rated this update as having a security impact
of Low. 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:

Release of RHACS 3.73 provides these changes:

New features:

* Red Hat Advanced Cluster Security Cloud Service (ACSCS) is a Red Hat
managed service that simplifies and accelerates RHACS deployments. ACSCS is
available as a Field Trial release. For more information about accessing
ACSCS, contact Red Hat Sales.
* Improved Vulnerability Management dashboard for ACSCS users.
* PostgreSQL database option is available as Technology Preview feature. If
you are interested in participating in the Tech Preview program, contact
your Red Hat account representative.
* A new build-time network policy generator as Technology Preview feature,
to generate Kubernetes network policies based on Application YAML
manifests.

Notable technical changes:

* RHACS uses GraphQL internally to show data in the RHACS portal. However,
Red Hat does not support querying RHACS using GraphQL. If you are using
GraphQL, see https://access.redhat.com/articles/6986289 and contact Red Hat
Consulting.
* Sensor no longer uses `anyuid` Security Context Constraint (SCC).
Instead, the default SCC for Sensor is now `restricted[-v2]` or
`stackrox-sensor`, depending on the settings. In addition, the `runAsUser`
and `fsGroup` for the Admission control and Sensor deployments are no
longer hard-coded to `4000` on OpenShift clusters to allow using the
`restricted` and `restricted-v2` SCCs. (ROX-9342)
* The service account `central`, which the Central deployment uses, now
includes `get` and `list` access to the pods, events, and namespaces
resources in the namespace where you deploy Central.
* The CSV export API `/api/vm/export/csv` now requires the `CVE Type`
filter as part of the input query parameter. Supported values for `CVE
Type` are `IMAGE_CVE`, `K8S_CVE`, `ISTIO_CVE`, `NODE_CVE`, and
`OPENSHIFT_CVE`.

Notice of in-product docs removal:

* Beginning in the RHACS 3.74 release, Red Hat will remove the in-product
docs accessible from the help menu. If you are using the in-product docs,
you can instead download the required documentation in PDF format from Red
Hat Customer Portal. (ROX-12839)

Bug fixes:

* Previously, if you were using StackRox Kubernetes Security Platform -
Splunk Technology Add-on, results for the `ocp4-cis-node` compliance
standard was missing from Splunk. This issue is now fixed. The Splunk
integration now includes the `ocp4-cis-node` compliance standard results.
(ROX-11937)
* Previously, Central would fail on the v1 CronJob deployment check. This
issue is fixed. (ROX-13500)

Security Fix(es):

* imgcrypt: Unauthorized access to encryted container image on a shared
system due to missing check in CheckAuthorization() code path
(CVE-2022-24778)

* app-containers/cosign: false positive verification (CVE-2022-36056)
