SUSE SLES15 / openSUSE 15 Security Update : kubernetes1.24 (SUSE-SU-2023:3260-1)

medium Nessus Plugin ID 179679

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3260-1 advisory.

- Users may be able to launch containers using images that are restricted by ImagePolicyWebhook when using ephemeral containers. Kubernetes clusters are only affected if the ImagePolicyWebhook admission plugin is used together with ephemeral containers. (CVE-2023-2727)

- Users may be able to launch containers that bypass the mountable secrets policy enforced by the ServiceAccount admission plugin when using ephemeral containers. The policy ensures pods running with a service account may only reference secrets specified in the service account's secrets field. Kubernetes clusters are only affected if the ServiceAccount admission plugin and the `kubernetes.io/enforce- mountable-secrets` annotation are used together with ephemeral containers. (CVE-2023-2728)

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

Solution

Update the affected kubernetes1.24-client, kubernetes1.24-client-bash-completion, kubernetes1.24-client-common and / or kubernetes1.24-client-fish-completion packages.
