Exploiting Lua 5.1 on 32-bit Windows

The following Lua program generates a Lua bytecode program called ignore-unsigned-sga.fnt, which in turn loads a DLL from within an extremely locked down Lua 5.1 sandbox in a program called RelicCOH2.exe. The remainder of this document attempts to explain how this program works by a whirlwind tour of relevent bits of the Lua 5.1 virtual machine.

if string.dump(function()end):sub(1, 12) ~= "\27Lua\81\0\1\4\4\4\8\0" then
  error("This generator requires a 32-bit version of Lua 5.1")

Redis + LibUV prototype README

Special thanks to Dušan Majkic (dmajkic, https://github.com/dmajkic/redis/) for his project on GitHub that gave us the opportunity to quickly learn some on the intricacies of Redis code. His project also helped us to build our prototype quickly.

Get source repository

First clone the Redis sources from https://github.com/antirez/redis.

• On your computer create a working folder and cd into it.
• Clone antirez/redis repository:
