github.com/prometheus/prometheus: Prometheus: Denial of Service via uncontrolled memory allocation in remote read endpoint

A flaw was found in Prometheus. An unauthenticated attacker can exploit the remote read endpoint /api/v1/read by sending a specially crafted, small snappy-compressed payload. This payload causes a disproportionately large memory allocation, leading to memory exhaustion and a Denial of Service DoS...
