    Summary: Updated dropbear packages fix security vulnerability

    Details: A double-free in the server could be triggered by an authenticated user if dropbear is running with -a (CVE-2017-9078). The default Mageia configuration does not set -a, so is not vulnerable Dropbear parsed authorized_keys as root, even if it were a symlink. The fix is to switch to user permissions when opening authorized_keys (CVE-2017-9079)
