In all Kubernetes versions prior to v1.10.11, v1.11.5, and v1.12.3, incorrect handling of error responses to proxied upgrade requests in the kube-apiserver allowed specially crafted requests to establish a connection through the Kubernetes API server to backend servers, then send arbitrary requests over the same connection directly to the backend, authenticated with the Kubernetes API server's TLS credentials used to establish the backend connection.

An update of the kubernetes package has been released.

The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2018-4303 advisory.

    - [CVE-2018-1002105] Handle error responses from backends

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

This update introduces kubernetes version 1.14.1 and cri-o 1.17.1 to Leap 15.1.

- Allow to install cri-o as alternative to docker

  - Allow to install moby-engine as alternative to docker

The version of a Docker container of Rancher is prior to 1.6.25, 2.0.9, or 2.1.3 and, thus, is affected by a proxy request handling flaw contained in Kubernetes.

A remote, unauthenticated attacker may be able to leverage API calls to escalate privileges via proxy request handling vulnerability.

Note that a successful attack requires that an API extension server is directly accessible from the Kubernetes API server's network or that a cluster has granted pod exec, attach, port-forward permissions too loosely.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:3754 advisory.

    Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution     designed for on-premise or private cloud deployments.

    Security Fix(es):

    * A privilege escalation vulnerability exists in OpenShift Container Platform 3.x which allows for     compromise of pods running on a compute node to which a pod is scheduled with normal user privilege. This     access could include access to all secrets, pods, environment variables, running pod/container processes,     and persistent volumes, including in privileged containers. Additionally, on versions 3.6 and higher of     OpenShift Container Platform, this vulnerability allows cluster-admin level access to any API hosted by an     aggregated API server. This includes the servicecatalog API which is installed by default in 3.7 and     later. Cluster-admin level access to the service catalog allows creation of brokered services by an     unauthenticated user with escalated privileges in any namespace and on any node. This could lead to an     attacker being allowed to deploy malicious code, or alter existing services. (CVE-2018-1002105)
