RHSA-2020:2479
Vulnerability from csaf_redhat - Published: 2020-06-18 21:12 - Updated: 2026-03-27 06:49libseccomp-golang 0.9.0 and earlier incorrectly generates BPFs that OR multiple arguments rather than ANDing them. A process running under a restrictive seccomp filter that specified multiple syscall arguments could bypass intended access restrictions by specifying a single matching argument.

The Kubernetes API Server component in versions 1.1-1.14, and versions prior to 1.15.10, 1.16.7 and 1.17.3 allows an authorized user who sends malicious YAML payloads to cause the kube-apiserver to consume excessive CPU cycles while parsing YAML.

A server side request forgery (SSRF) flaw was found in Kubernetes. The kube-controller-manager allows authorized users with the ability to create StorageClasses or certain Volume types to leak up to 500 bytes of arbitrary information from the master's host network. This can include secrets from the kube-apiserver through the unauthenticated localhost port (if enabled).
