They are also the projects that get the most attention. I wouldn't rule out that python/javascript/whatever projects have just as many, if not even more, security flaws than your typical widely-used C library. They are just not interesting enough to warrant the required attention. The flaws are likely to be more subtle than simple buffer overflows too, think of all the abstractions involved.
