compatibility issue with Archive::Zip::Member v1.30?

I'm seeing MailScanner 4.81.4 return "MailScanner: Message attempted to
kill MailScanner" every time it tries to process an .xlsx file
(Microsoft Excel 2010's format). IIRC the format is a zip container with
the actual Excel data inside it.
When I run MailScanner in debug mode and send one of these files through
I get the error message:
Insecure dependency in chmod while running with -T switch at
/opt/perl5/lib/site_perl/5.12.2/Archive/Zip/Member.pm line 490.
That line in Member.pm (v1.30) says:
chmod ($self->unixFileAttributes(), $name)
My guess is that $name is being passed down, hasn't been checked
anywhere and so is causing a taint issue.
Should I just do a local rebuild of this module that does $name =~ /.*/
to fix this issue for now and then submit it as a patch back to the
vendor? Just modifying the code like this doesn't seem like a great long
term solution though as it could be a security risk?
