Hi Russ,
I'd expect that if your C library has security issues, then using Lua
or anything else that interfaces to that library will not protect you.
For example, if your C code has buffer overflows, it doesn't matter
how it is called - the overflow is there and will potentially cause
you grief when the code is run. You'll need to fix up your C code.
Cheers,
Tim.

Thanks Florian. So does interfacing a C library (written poorly by
me!) with Lua protect me from potential vulnerabilities in that library?

* Russell Haley:
I have understood that some languages written in C suffer from
security vulnerabilities inherent in the host language.
That's only true for languages which provide access to the C type
system or something closely related (C++ is the prime example). Lua
does not do this.
