Synopsis

The remote Red Hat CoreOS host is missing a security update for OpenShift Container Platform 4.12.24.

Description

The remote Red Hat Enterprise Linux CoreOS 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2023:3976 advisory.

 - An authentication bypass vulnerability was discovered in kube-apiserver. This issue could allow a remote, authenticated attacker who has been given permissions update, patch the pods/ephemeralcontainers subresource beyond what the default is. They would then need to create a new pod or patch one that they already have access to. This might allow evasion of SCC admission restrictions, thereby gaining control of a privileged pod. (CVE-2023-1260)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHCOS OpenShift Container Platform 4.12.24 packages based on the guidance in RHSA-2023:3976.
