working directory due to a wrong function argument. This update will
create temporary files in the users home directory if HOME is set or
in the common temporary directory otherwise, usually /tmp. For
completeness below is a copy of the original advisory text :

  Niko Tyni discovered that the Mail::Audit module, a Perl library for
  creating simple mail filters, logs to a temporary file with a
  predictable filename in an insecure fashion when logging is turned
  on, which is not the case by default."
