Descriptions

Dropbear before 2017.75 might allow local users to read certain files as root, if the file has the authorized_keys file format with a command= option. This occurs because ~/.ssh/authorized_keys is read with root privileges and symlinks are followed.

Dropbear anteriores a 2017.75 podría permitir a usuarios locales leer ciertos archivos como usuario root, si el archivo tiene el formato de archivo authorized_keys con un comando=opción. Esto ocurre porque ~ /.ssh/authorized_keys se lee con privilegios de root y se siguen los enlaces simbólicos.
