CVE-2020-24342 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:20.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream lua5.3 package and not the lua5.3 package as distributed by Ubuntu.
Lua through 5.4.0 allows a stack redzone cross in luaO_pushvfstring because a protection mechanism wrongly calls luaD_callnoyield twice in a row.
