Re:Make CPython segfault in 5 lines of code by lpghatguy on Thursday December 19, 2019 @02:04PM (#21838071)
Here are two slide decks talking (roughly) about real-world attacks against Lua 5.1 and 5.2's bytecode:

5.1: https://www.lua.org/wshop11/Cawley.pdf

5.2: https://apocrypha.numin.it/talks/lua_bytecode_exploitation.p...

Lua used to have a built-in bytecode verifier as I understand it, but it never reached the point to where it was enough to safeguard the VM.
