Description

The former update caused temporary files to be created in the current 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.
