### CVE-2021-25735: Validating Admission Webhook does not observe some previous fields

A security issue was discovered in kube-apiserver that could allow node
updates to bypass a Validating Admission Webhook. You are only affected
by this vulnerability if you run a Validating Admission Webhook for Nodes
that denies admission based at least partially on the old state of the
Node object.

A security issue was discovered in Kubernetes where a user may be able to
create a container with subpath volume mounts to access files &
directories outside of the volume, including on the host filesystem.

**Affected Versions**:
  - kubelet v1.22.0 - v1.22.1
  - kubelet v1.21.0 - v1.21.4
  - kubelet v1.20.0 - v1.20.10
  - kubelet <= v1.19.14

**Fixed Versions**:
  - kubelet v1.22.2
  - kubelet v1.21.5

that are required to deploy and operate Kubernetes workloads.

For the 1.8 release, SIG Apps moved the Kubernetes workloads API to the new apps/v1beta2 group and version. The DaemonSet, Deployment, ReplicaSet, and StatefulSet objects are affected by this change. The new apps/v1beta2 group and version provide a stable and consistent API surface for building applications in Kubernetes. For details about deprecations and behavioral changes, see [Notable Features](#notable-features). SIG Apps...

Other then that, this release contains no other changes from 1.5.4.

The vulnerability is tracked in http://issue.k8s.io/43459.

**Who is affected?**

Only Kubernetes 1.5.0-1.5.4 installations that do all of the following:
* Enable the PodSecurityPolicy API (which is not enabled by default):
  * `--runtime-config=extensions/v1beta1/podsecuritypolicy=true`

will use the local kube-apiserver endpoint for the kubelet when creating a cluster with `kubeadm init` or when joining control plane nodes with `kubeadm join`. Enabling the feature gate also affects the `kubeadm init phase kubeconfig kubelet` phase, where the flag `--control-plane-endpoint` no longer affects the generated kubeconfig `Server` field, but the flag `--apiserver-advertise-address` can now be used for the same purpose. ([#129956](https://github.com/kubernetes/kubernetes/pull/129956), ...

file](https://kubernetes.io/docs/tasks/administer-cluster/kubelet-config-file/) are now deprecated in favor of the file. ([#60148](https://github.com/kubernetes/kubernetes/pull/60148), [@mtaufen](https://github.com/mtaufen))

* `--show-all` (which only affected pods and only for human readable/non-API printers) is now defaulted to true and deprecated.  The flag determines whether pods in a terminal state are displayed. It will be inert in 1.11 and removed in a future release. ([#60210](https://github.c...
