Not to mention that *all* versions of Perl prior to 5.004 have known,
documented buffer-overflow potential problems, so if you use those
scripts in any public-execution environment (like CGI or setuid
programs or daemons), you are setting yourself up for a "non use of
best practices" lawsuit when the bad guys break in.
I'm told by people in-the-know of a rootkit that targets *any* CGI
script and sends it the right thing to break in, presuming you know
the arch of the box and have a reasonable guess as to the Perl
Perl 4 is dead. Anything before 5.004 is dangerous. Perl5 *is* Perl.
