OpenShift Enterprise by Red Hat is the company's cloud computingPlatform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.An authorization flaw was discovered in Kubernetes; the API server did not properly check user permissions when handling certain requests. Anauthenticated remote attacker could use this flaw to gain additional access to resources such as RAM and disk space. (CVE-2016-1905)An authorization flaw was discovered in Kubernetes; the API server did not properly check user permissions when handling certain buildconfiguration strategies. A remote attacker could create build configurations with strategies that violate policy. Although the attacker could not launch the build themselves (launch fails when the policy is violated), if the build configuration files were later launched by other privileged services (such as automated triggers), user privileges could be bypassed allowing attacker escalation. (CVE-2016-1906)All OpenShift Enterprise 3.0 users are advised to upgrade to these updated packages.
