The VOLUME directive in a Dockerfile (config.volumes in the OCI image configuration) is only a hint and is not handled specially by Kubernetes, but containerd adds a mount point for it when Kubernetes sets none, requiring the runtime to be able to push arbitrary data to the Kata agent. As a result, on bare-metal Contrast deployments (AKS deployments are not affected) that run an image declaring at least one VOLUME for which no Kubernetes mount exists at that path, the untrusted host can write arbitrary file trees below that mount point inside the confidential container, compromising the integrity of a directory that is typically important to the application's core functionality. Version 1.9.1 fixes the issue by disallowing this configuration in `contrast generate`."}, {"lang": "es", "value": "Contrast, el entorno de ejecuci\u00f3n de Edgeless Systems para contenedores confidenciales en Kubernetes, est\u00e1 afectado en versiones hasta e incluyendo 1.9.0. La directiva VOLUME en un Dockerfile (config.volumes en la configuraci\u00f3n de imagen OCI) es solo una sugerencia y no es manejada de forma especial por Kubernetes, pero containerd a\u00f1ade un punto de montaje para ella cuando Kubernetes no establece ninguno, lo que requiere que el entorno de ejecuci\u00f3n pueda enviar datos arbitrarios al agente de Kata. Como resultado, en despliegues de Contrast en hardware dedicado (bare-metal) (los despliegues de AKS no est\u00e1n afectados) que ejecutan una imagen que declara al menos un VOLUME para el cual no existe un montaje de Kubernetes en esa ruta, el host no confiable puede escribir \u00e1rboles de archivos arbitrarios debajo de ese punto de montaje dentro del contenedor confidencial, comprometiendo la integridad de un directorio que es t\u00edpicamente importante para la funcionalidad central de la aplicaci\u00f3n.
