"value": "A vulnerability in Google Cloud Platform's guest-oslogin versions between 20190304 and 20200507 allows a user that is only granted the role \"roles/compute.osLogin\" to escalate privileges to root. Using the membership to the \"lxd\" group, an attacker can attach host devices and filesystems. Within an lxc container, it is possible to attach the host OS filesystem and modify /etc/sudoers to then gain administrative privileges. All images created after 2020-May-07 (20200507) are fixed, and if you cannot update, we recommend you edit /etc/group/security.conf and remove the \"lxd\" user from the OS Login entry."

Usando la membres\u00eda en el grupo \"lxd\", un atacante puede conectar dispositivos host y sistemas de archivos. Dentro de un contenedor lxc, es posible adjuntar el sistema de archivos del sistema operativo host y modificar /etc/sudoers para luego obtener privilegios administrativos.
