Vulnerability Title
Use-after-free in Envoy
Vulnerability Description
Envoy is an open source edge and service proxy, designed for cloud-native applications. Sending a locally generated response must stop further processing of request or response data. Envoy tracks the amount of buffered request and response data and aborts the request if the amount of buffered data is over the limit by sending 413 or 500 responses. However when the buffer overflows while response is processed by the filter chain the operation may not be aborted correctly and result in accessing a freed memory block. If this happens Envoy will crash resulting in a denial of service.

Vulnerability Title
Envoy 资源管理错误漏洞
Vulnerability Description
Envoy是一款开源的分布式代理服务器。 Envoy 存在资源管理错误漏洞，该漏洞源于Envoy跟踪缓冲的请求和响应数据的数量，如果缓冲数据的数量超过限制，就发送413或500个响应，从而中止请求。然而当缓冲区溢出时，响应由过滤器链处理，操作可能不会正确中止，并导致访问一个释放的内存块。攻击者可利用该漏洞导致拒绝服务。
