Summary

lua security update

Details

Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description.

Security Fix(es):

singlevar in lparser.c in Lua through 5.4.4 lacks a certain luaK_exp2anyregup call, leading to a heap-based buffer over-read that might affect a system that compiles untrusted Lua code.(CVE-2022-28805)

Lua 5.4.4 and 5.4.2 are affected by SEGV by type confusion in funcnamefromcode function in ldebug.c which can cause a local denial of service.(CVE-2021-44647)

Severity

9.1 (Critical)
