Vulnerability Title
KubeEdge Edge ServiceBus module DoS
Vulnerability Description
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 ServiceBus server on the edge side may be susceptible to a DoS attack if an HTTP request containing a very large Body is sent to it. It is possible for the node to be exhausted of memory. The consequence of the exhaustion is that other services on the node, e.g. other containers, will be unable to allocate memory and thus causing a denial of service. Malicious apps accidentally pulled by users on the host and have the access to send HTTP requests to localhost may make an attack. It will be affected only when users enable the `ServiceBus` 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 the `ServiceBus` module in the config file `edgecore.yaml`.

Vulnerability Title
KubeEdge 资源管理错误漏洞
Vulnerability Description
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之前版本存在资源管理错误漏洞，该漏洞源于如果向其发送包含非常大 Body 的 HTTP 请求，边缘侧的 ServiceBus 服务器可能容易受到 DoS 攻击，攻击者利用该漏洞可以发送大消息来耗尽内存并导致 DoS。
