Summary
Red Hat Security Advisory: kubernetes security update
Notes
Topic
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.
Details
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.
