      "value": "Kata Containers is an open source project focusing on a standard implementation of lightweight Virtual Machines (VMs) that perform like containers. In versions prior to 3.27.0, an issue in Kata with Cloud Hypervisor allows a user of the container to modify the file system used by the Guest micro VM ultimately achieving arbitrary code execution as root in said VM. The current understanding is this doesn\u2019t impact the security of the Host or of other containers / VMs running on that Host (note that arm64 QEMU lacks NVDIMM read-only support: It is believed that until the upstream QEMU gains this capability, a guest write could reach the image file). Version 3.27.0 patches the issue."

En versiones anteriores a la 3.27.0, un problema en Kata con Cloud Hypervisor permite a un usuario del contenedor modificar el sistema de archivos utilizado por la micro VM Invitada, logrando en \u00faltima instancia la ejecuci\u00f3n de c\u00f3digo arbitrario como root en dicha VM. El entendimiento actual es que esto no impacta la seguridad del Host o de otros contenedores / VMs ejecut\u00e1ndose en ese Host (tenga en cuenta que QEMU arm64 carece de soporte de solo lectura NVDIMM: Se cree que hasta que el QEMU upstream obtenga esta capacidad, una escritura de invitado podr\u00eda alcanzar el archivo de imagen). La versi\u00f3n 3.27.0 parchea el problema."
