CVE-2022-21211 - Unhandled crash in npm posix

[tucks]

This affects all versions of package posix. When invoking the toString method, it will fallback to 0x0 value, as the value of toString is not invokable (not a function), and then it will crash with type-check.

For what it is worth, I happened to create another node.js package (inspired by this one) that doesn't have this vulnerability:

https://www.npmjs.com/package/posix-node

I'm not claiming it doesn't have any other vulnerabilities or possibly even worse ones -- the very nature of this posix module is that it involves some dangerous functionality nodejs doesn't expose.
