      "value": "Incus is a system container and virtual machine manager. Prior to version 7.0.0, uploads of large amount of data by authenticated users can run the Incus server out of disk space, potentially taking down the host system. The impact here is limited for anyone using storage.images_volume and storage.backups_volume as those users will have large uploads be stored on those volumes rather than directly on the host filesystem. This is the default behavior on IncusOS. This issue has been patched in version 7.0.0."

      "value": "Incus es un gestor de contenedores de sistema y máquinas virtuales. Antes de la versión 7.0.0, las cargas de grandes cantidades de datos por parte de usuarios autenticados pueden agotar el espacio en disco del servidor Incus, lo que podría provocar la caída del sistema anfitrión. El impacto aquí es limitado para cualquiera que utilice storage.images_volume y storage.backups_volume, ya que las cargas grandes de esos usuarios se almacenarán en esos volúmenes en lugar de directamente en el sistema de archivos del anfitrión. Este es el comportamiento predeterminado en IncusOS. Este problema ha sido parcheado en la versión 7.0.0."
