github.com/envoyproxy/envoy is vulnerable to Denial Of Service. This vulnerability is due to not resetting a request when header map limits are exceeded, allowing attackers to send a sequence of CONTINUATION frames without the END_HEADERS bit set, leading to unlimited memory consumption and denial of service through memory exhaustion.
