Descriptions

The bsdinstall installer in FreeBSD 10.x before 10.1 p9, when configuring full disk encrypted ZFS, uses world-readable permissions for the GELI keyfile (/boot/encryption.key), which allows local users to obtain sensitive key information by reading the file.

El instalador bsdinstall en FreeBSD 10.x anterior a 10.1 p9, cuando configura ZFS codificado de disco completo, utiliza permisos de lectura universal para el fichero de claves GELI (/boot/encryption.key), lo que permite a usuarios locales obtener información sensible de claves mediante la lectura del fichero.

FreeBSD 10.x installer supports the installation of FreeBSD 10.x on an encrypted ZFS filesystem by default. When using the encryption system within ZFS during the installation of FreeBSD 10.0 and FreeBSD 10.1, the encryption.key has wrong permissions which allow local users to read this file. Even if the keyfile is passphrase-encrypted, it can present a risk.
