CVE-2016-3708

Red Hat OpenShift Enterprise 3.2, cuando multi-tenant SDN está habilitado y un build está ejecutado en un espacio de nombres que normalmente estaría aislado de pods en otros espacios de nombres, permite a usuarios remotos autenticados acceder a recursos de red en pods restringidos a través de un build s2i con una imagen builder que (1) contiene comandos ONBUILD o (2) no contiene un binario tar.

A flaw was found in OpenShift Enterprise when multi-tenant SDN is enabled and a build is run within a namespace that would normally be isolated from pods in other namespaces. If an s2i build is run in such an environment the container being built can access network resources on pods that should not be available to it.

OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service solution designed for on-premise or private cloud deployments. Security Fix: A vulnerability was found in the STI build process in OpenShift Enterprise. Access to STI builds was not properly restricted, allowing an attacker to use STI builds to access the Docker socket and escalate their privileges.
