alt Hacker NewsThank you for your concern.
I fixed CVE-2014-5461 for Lunacy back in 2021:
https://github.com/samboy/lunacy/commit/4de84e044c1219b06744...
This is discussed here:
https://samboy.github.io/MaraDNS/webpage/security.html#CVE-2...
In addition, I have done other security hardening with Lunacy compared to Lua 5.1:

Now, I should probably explain why I’m using Lua 5.1 instead of the latest “official” version of Lua. Lua has an interesting history; in particular Lua 5.1 is the most popular version and the version which is most commonly used or forked against. Adobe Illustrator uses Lua 5.1, and Roblox uses a fork of Lua 5.1 called “luau”. LuaJIT is based on Lua 5.1, and other independent implementations of Lua (Moonsharp, etc.) are based on versions mostly compatible with Lua 5.1.
Lua 5.1 has a remarkably good security history, and of course I take responsibility for any security bugs in the Lua 5.1 codebase since I use the code with the relatively new coLunacyDNS server (Lua 5.1 isn’t used with the MaraDNS or Deadwood servers).
Lua 5.1 is used to convert documentation, but those scripts are run offline and the converted documents are part of the MaraDNS Git tree.
Yeah, I've had patches submitted to Moonscript, Fengari, and luau. Don't need to sell on why 5.1 is useful. Each version is a new lang, not just a few fixes or niceties.
I'm not convinced that vendoring, instead of embedding, is the right way.
The patch landing in 2021, instead of 2014, being one of those concerns.
(And you might want to recheck your assumption of how big 'int' will be, for rg32. C defines it in terms of minimum size, not direct size. int16_t isn't necessarily an alias.)
