Lua JLS

In Lua 5.4.3, an erroneous finalizer called during a tail call leads to a heap-based buffer over-read.

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.

singlevar in lparser.c in Lua from (including) 5.4.0 up to (excluding) 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.

Use after free in garbage collector and finalizer of lgc.c in Lua interpreter 5.4.0~5.4.3 allows attackers to perform Sandbox Escape via a crafted script file.

Lua v5.4.3 and above are affected by SEGV by type confusion in funcnamefromcode function in ldebug.c which can cause a local denial of service.

Stack overflow in lua_resume of ldo.c in Lua Interpreter 5.1.0~5.4.4 allows attackers to perform a Denial of Service via a crafted script file.

lgc.c in Lua 5.4.0 mishandles the interaction between barriers and the sweep phase, leading to a memory access violation involving collectgarbage.

ldebug.c in Lua 5.4.0 allows a negation overflow and segmentation fault in getlocal and setlocal, as demonstrated by getlocal(3,2^31).
