Hi,

The following vulnerability was published for lua5.4.

CVE-2022-33099[0]:
| An issue in the component luaG_runerror of Lua v5.4.4 and below leads
| to a heap-buffer overflow when a recursive error occurs.

Btw, I'm right now not sure about older lua versions. While the patch
im principle I think apply I'm unsure if the issue has introduced in
5.4 only. Can you double check so we can update the tracker
accordingly?

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
