Envoy crashes for LocalReply in http async client

Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy will crash when the http async client is handling `sendLocalReply` under some circumstance, e.g., websocket upgrade, and requests mirroring. The http async client will crash during the `sendLocalReply()` in http async client, one reason is http async client is duplicating the status code, another one is the destroy of router is called at the destructor of the async stream, while the stream is deferred deleted at first. There will be problems that the stream decoder is destroyed but its reference is called in `router.onDestroy()`, causing segment fault. This will impact ext_authz if the `upgrade` and `connection` header are allowed, and request mirrorring. This issue has been addressed in versions 1.31.2, 1.30.6, 1.29.9, and 1.28.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Envoy 缓冲区错误漏洞

Envoy是Enphase开源的一款用于连接智能家居设备的网关程序。 Envoy 1.32.0之前版本存在缓冲区错误漏洞，该漏洞源于当http async客户端在某些情况下处理sendLocalReply时，Envoy会崩溃。
