Perl doesn't have buffer overflows, but Perl-based web applications have had tons of security holes, mostly caused by not sufficiently checking user-supplied data (../../.. in paths, cross-site scripting, and the like).

Language versus application security Posted Jan 31, 2003 0:54 UTC (Fri) by copsewood (subscriber, #199) [Link] Yep. The approach of deciding what valid data should look like and excluding everything else is similar to the default-deny approach to firewall setups. This can reduce functionality slightly or slightly increases the effort of getting added functionality secure, but its probably much less hassle than trying specifically to exclude what is considered dangerous when you can only ever have limited knowledge of what might be exploitable in future.
