Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2019-9512)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper validation of user-supplied input when processing HTTP/2 requests. A remote attacker can send specially crafted HTTP packets to the affected system trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2019-9514)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper validation of user-supplied input when processing HTTP/2 requests. A remote attacker can send specially crafted HTTP packets to the affected system trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2019-11247)
The vulnerability allows a remote authenticated user to read and manipulate data.
The Kubernetes kube-apiserver mistakenly allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges). Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.7, 1.8, 1.9, 1.10, 1.11, 1.12.
