Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared directory, a denial of service may occur. This flaw allows a guest user/process to cause this denial of service on the host." }, { "lang": "es", "value": "Se encontr\u00f3 un fallo potencial de DoS en la implementaci\u00f3n del demonio del sistema de archivos compartido virtio-fs (virtiofsd) de QEMU versiones anteriores a la versi\u00f3n v5.0. Virtio-fs est\u00e1 destinado a compartir un directorio del sistema de archivos host con un invitado por medio de un dispositivo virtio-fs. Si el invitado abre el n\u00famero m\u00e1ximo de descriptores de archivo en el directorio compartido, puede ocurrir una denegaci\u00f3n de servicio.
