The API server in Kubernetes does not properly check admission control, which allows remote authenticated users to access additional resources via a crafted patched object.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The API server in Kubernetes does not properly check admission control, which allows remote authenticated     users to access additional resources via a crafted patched object. (CVE-2016-1905)

Red Hat OpenShift Enterprise release 3.1.1 is now available with updates to packages that fix several security issues, bugs and introduce feature enhancements.

Red Hat Product Security has rated this update as having Important 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.

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.

The following security issues are addressed with this release :

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)

An update for Jenkins Continuous Integration Server that addresses a large number of security issues including XSS, CSRF, information disclosure and code execution have been addressed as well.
