Summary: Updated kubernetes packages that fix two security issues are now available for Red Hat OpenShift Enterprise 3.0.2. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat OpenShift Enterprise 3.0 - x86_64 3. Description: OpenShift Enterprise by Red Hat is the company's cloud computing Platform-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. An authenticated 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 build configuration 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1297910 - CVE-2016-1905 Kubernetes api server: patch operation should use patched object to check admission control 1297916 - CVE-2016-1906 Kubernetes api server: build config to a strategy that isn't allowed by policy 6.
