Descriptions

Improper exposure of client IP addresses in net/http before Go 1.17.12 and Go 1.18.4 can be triggered by calling httputil.ReverseProxy.ServeHTTP with a Request.Header map containing a nil value for the X-Forwarded-For header, which causes ReverseProxy to set the client IP as the value of the X-Forwarded-For header.

Una exposición inapropiada de las direcciones IP de los clientes en net/http versiones anteriores a Go 1.17.12 y Go 1.18.4, puede desencadenarse llamando a httputil.ReverseProxy.ServeHTTP con un mapa Request.Header que contenga un valor nulo para el encabezado X-Forwarded-For, lo que causa que ReverseProxy establezca la IP del cliente como valor de el encabezado X-Forwarded-For

A flaw was found in net/http/httputil golang package. When httputil.ReverseProxy.ServeHTTP is called with a Request.Header map containing a nil value for the X-Forwarded-For header, ReverseProxy could set the client IP incorrectly. This issue may affect confidentiality.

Multicluster engine for Kubernetes 2.1 images Multicluster engine for Kubernetes provides the foundational components that are necessary for the centralized management of multiple Kubernetes-based clusters across data centers, public clouds, and private clouds. You can use the engine to create new Red Hat OpenShift Container Platform clusters or to bring existing Kubernetes-based clusters under management by importing them. After the clusters are managed, you can use the APIs that are provided by the engine to distribute configuration based on placement policy. Issues addressed include a denial of service vulnerability.
