CVE-2020-15888 WRITEUP HIGH WRITEUP
Lua - Out-of-Bounds Write
Lua through 5.4.0 mishandles the interaction between stack resizes and garbage collection, leading to a heap-based buffer overflow, heap-based buffer over-read, or use-after-free.
CVSS 8.8
CVE-2020-15889 WRITEUP CRITICAL WRITEUP
Lua - Out-of-Bounds Read
Lua 5.4.0 has a getobjname heap-based buffer over-read because youngcollection in lgc.c uses markold for an insufficient number of list members.

CVE-2020-15945 WRITEUP MEDIUM WRITEUP
Lua 5.4.0 - Memory Corruption
Lua 5.4.0 (fixed in 5.4.1) has a segmentation fault in changedline in ldebug.c (e.g., when called by luaG_traceexec) because it incorrectly expects that an oldpc value is always updated upon a return of the flow of control to a function.
CVSS 5.5
CVE-2020-24342 WRITEUP HIGH WRITEUP
Lua <5.4.0 - Memory Corruption
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.

CVE-2020-24371 WRITEUP MEDIUM WRITEUP
Lua 5.4.0 - Memory Corruption
lgc.c in Lua 5.4.0 mishandles the interaction between barriers and the sweep phase, leading to a memory access violation involving collectgarbage.
CVSS 5.3
CVE-2021-45985 WRITEUP HIGH WRITEUP

CVE-2022-28805 WRITEUP CRITICAL WRITEUP
Lua <5.4.4 - Buffer Overflow
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.
CVSS 9.1
CVE-2022-33099 WRITEUP HIGH WRITEUP
Lua <5.4.4 - Buffer Overflow
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.
