Red Hat Security Advisory: Red Hat OpenShift support for Windows Containers 7.0.0 [security update]
Severity
Moderate
Notes
Topic: The components for Red Hat OpenShift support for Windows Container 7.0.0 are now
available. This product release includes bug fixes and a moderate security
update for the following packages: windows-machine-config-operator and
windows-machine-config-operator-bundle.
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.
Details: Red Hat OpenShift support for Windows Containers allows you to deploy Windows container workloads running on Windows Server containers.
Security Fix(es):
* prometheus/client_golang: Denial of service using InstrumentHandlerCounter (CVE-2022-21698)
* golang: crash in a golang.org/x/crypto/ssh server (CVE-2022-27191)
* kubelet: runAsNonRoot logic bypass for Windows containers (CVE-2021-25749)
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.

A flaw was found in Kubernetes. This issue allows Windows workloads to run as a ContainerAdministrator even when the workloads set the runAsNonRoot option to true.
CWE-842 - Placement of User into Incorrect Group
Vendor Fix
For details on how to apply this update, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:9096
A denial of service attack was found in prometheus/client_golang. This flaw allows an attacker to produce a denial of service attack on an HTTP server by exploiting the InstrumentHandlerCounter function in the version below 1.11.1, resulting in a loss of availability.
7.5 (High)
Vendor Fix
For details on how to apply this update, refer to:
https://access.redhat.com/articles/11258
https://access.redhat.com/errata/RHSA-2022:9096
A broken cryptographic algorithm flaw was found in golang.org/x/crypto/ssh. This issue causes a client to fail authentication with RSA keys to servers that reject signature algorithms based on SHA-2, enabling an attacker to crash the server, resulting in a loss of availability.
7.5 (High)
Vendor Fix
