Описание
Improper input validation in the Kubernetes API server in versions v1.0-1.12 and versions prior to v1.13.12, v1.14.8, v1.15.5, and v1.16.2 allows authorized users to send malicious YAML or JSON payloads, causing the API server to consume excessive CPU or memory, potentially crashing and becoming unavailable. Prior to v1.14.0, default RBAC policy authorized anonymous users to submit requests that could trigger this vulnerability. Clusters upgraded from a version prior to v1.14.0 keep the more permissive policy by default for backwards compatibility.
A flaw was found kubernetes. The parsing of YAML manifests by the Kubernetes API server could lead to a denial-of-service attack leaving it vulnerable to an instance of a "billion laughs" attack. The highest threat from this vulnerability is to system availability.
Отчет
For Red Hat OpenStack Platform, because kubernetes is not directly used in director-operator, the RHOSP Impact has been moved to Moderate.
