Descriptions

The admin command in ceph-deploy before 1.5.25 uses world-readable permissions for /etc/ceph/ceph.client.admin.keyring, which allows local users to obtain sensitive information by reading the file.

El comando de administración en ceph-deploy anterior a 1.5.25 utiliza permisos de lectura universal para /etc/ceph/ceph.client.admin.keyring, lo que permite a usuarios locales obtener información sensible mediante la lectura del fichero.

It was discovered that ceph-deploy, a utility for deploying Red Hat Ceph Storage, would create the keyring file with world readable permissions, which could possibly allow a local user to obtain authentication credentials from the keyring file.
