Important Security Information

This release contains changes that address the following vulnerabilities:

CVE-2023-3955: Insufficient input sanitization on Windows nodes leads to privilege escalation

A security issue was discovered in Kubernetes where a user that can create pods on Windows nodes may be able to escalate to admin privileges on those nodes. Kubernetes clusters are only affected if they include Windows nodes.

Affected Versions:

kubelet <= v1.28.0
kubelet <= v1.27.4
kubelet <= v1.26.7
kubelet <= v1.25.12
kubelet <= v1.24.16

Fixed Versions:

kubelet v1.28.1
kubelet v1.27.5
kubelet v1.26.8
kubelet v1.25.13
kubelet v1.24.17

This vulnerability was discovered by James Sturtevant @jsturtevant and Mark Rossetti @marosset during the process of fixing CVE-2023-3676 (that original CVE was reported by Tomer Peled @tomerpeled92)

CVSS Rating: High (8.8) CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
