Description Mark Cooper 2020-05-08 01:29:34 UTC 
A vulnerability was found in all versions of istio/envoy, v1.4.8 (running Telemetry v2 non-default) and v1.5.2 (running Telemetry v2 by default). A remote attacker may send a specially crafted packet to the ingress gateway or sidecar, triggering a null pointer exception which results in a denial of service.
