Security risks when invoking ghostscript

Hi all,
it seems ghostscript look for all files in current directory before
searching in its preferred path. This is its default behaviour. The way
to disable it, is to use option "-P-"[1]. There a few bug reports
signalling this problem, as for [2] (the latest one) and [3] (the first
one).

What is your opinion about this problem when gs is invoked by hylafax?
Is there any real risks?

Thanks,
Giuseppe
