KubeEdge Cloud Stream and Edge Stream DoS from large stream message

KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, the Cloud Stream server and the Edge Stream server reads the entire message into memory without imposing a limit on the size of this message. An attacker can exploit this by sending a large message to exhaust memory and cause a DoS. The Cloud Stream server and the Edge Stream server are under DoS attack in this case. The consequence of the exhaustion is that the CloudCore and EdgeCore will be in a denial of service. Only an authenticated user can cause this issue. It will be affected only when users enable `cloudStream` module in the config file `cloudcore.yaml` and enable `edgeStream` module in the config file `edgecore.yaml`. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. As a workaround, disable cloudStream module in the config file `cloudcore.yaml` and disable edgeStream module in the config file `edgecore.yaml`.

KubeEdge 资源管理错误漏洞

KubeEdge是KubeEdge开源的一个 Kubernetes 原生边缘计算框架。基于 Kubernetes 构建，并将本机容器化应用编排和设备管理扩展到边缘主机。 KubeEdge 1.11.1之前版本、1.10.2之前版本 和 1.9.4之前版本存在安全漏洞，该漏洞源于Cloud Stream 服务器和 Edge Stream 服务器将整条消息读入内存，而不限制此消息的大小，攻击者利用该漏洞可以发送大消息来耗尽内存并导致 DoS。
