As far as I can see, they have security implications if you run
untrusted script code (or untrusted bytecode).  I don't think we've
got such software in our code base, but I might be mistaken.

There are additional issues if you run untrusted bytecode, these
issues haven't been fixed (and are very difficult to fix).

Please check out the Open Source Software Security Wiki, which is counterpart to this mailing list.
