Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2021-04-17 18:57:36 UTC
CVE-2021-25735:

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.

Note: This only impacts validating admission plugins that rely on old values in certain fields, and does not impact calls from kubelets that go through the built-in NodeRestriction admission plugin.

This release also addresses CVE-2021-3121 (see also bug 765046).


Fixes in 1.20.6, 1.19.10, and 1.18.18. Please bump.
