(policyd-weight: Insecure temporary file creation)

    Chris Howells reported that policyd-weight creates and uses the
    '/tmp/.policyd-weight/' directory in an insecure manner.
  
Impact :

    A local attacker could exploit this vulnerability to delete arbitrary
    files or change the ownership to the 'polw' user via symlink attacks.
  
Workaround :

    Set '$LOCKPATH = '/var/run/policyd-weight/'' manually in
    '/etc/policyd-weight.conf'."

    This version changes the default path for sockets to
    '/var/run/policyd-weight', which is only writable by a privileged user.
    Users need to restart policyd-weight immediately after the upgrade due
    to this change."
