RedHat: RHSA-2016-0351:01 Moderate: kubernetes security update
Summary
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.
