CVE-2015-4053

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.

Red Hat Ceph Storage is a massively scalable, open, software-defined storage platform that combines the most stable version of Ceph with a Ceph management platform, deployment tools, and support services. 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. All ceph-deploy users are advised to upgrade to this updated package, which contains backported patches to correct these issues.
