13 Oct 2022 — Istio is an open platform-independent service mesh that provides traffic management, policy enforcement, and telemetry collection. Prior to versions 1.15.2, 1.14.5, and 1.13.9, the Istio control plane, istiod, is vulnerable to a request processing error, allowing a malicious attacker that sends a specially crafted or oversized message which results in the control plane crashing when the Kubernetes validating or mutating webhook service is exposed publicly. This endpoint is served over TLS port 15017, but do... • https://github.com/istio/istio/security/advisories/GHSA-86vr-4wcv-mm9w • CWE-400: Uncontrolled Resource Consumption •
