Lua script as data model

[LAURENS Jérôme <jlaurens@...>]

Hi list,

I am new to lua.

I plan to store some key->value preferences (and more) in a lua script  
file.
My question concerns security:
in case the script file is corrupted, is it possible to execute  
malicious code while lua is scanning back the file?
In general, are there any required steps to prevent security issues  
when using lua scripts as data models?

TIA.
