- CVE-2021-44964Use 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.6.3
- CVE-2021-44647Lua 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.5.5
- CVE-2021-43519Stack 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.5.5
- CVE-2020-24369ldebug.c in Lua 5.4.0 attempts to access debug information via the line hook of a stripped function, leading to a NULL pointer dereference.7.5
- CVE-2020-24371lgc.c in Lua 5.4.0 mishandles the interaction between barriers and the sweep phase, leading to a memory access violation involving collectgarbage.5.3
- CVE-2020-24370ldebug.c in Lua 5.4.0 allows a negation overflow and segmentation fault in getlocal and setlocal, as demonstrated by getlocal(3,2^31).5.3
- CVE-2020-24342Lua through 5.4.0 allows a stack redzone cross in luaO_pushvfstring because a protection mechanism wrongly calls luaD_callnoyield twice in a row.7.8
- CVE-2020-15945Lua 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 retu...5.5
- CVE-2020-15888Lua 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.8.8
- CVE-2020-15889Lua 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.9.8
- CVE-2019-6706Lua 5.3.5 has a use-after-free in lua_upvaluejoin in lapi.c. For example, a crash outcome might be achieved by an attacker who is able to trigger a debug.upvaluejoin call in which the arguments hav...7.5
- CVE-2014-5461Buffer overflow in the vararg functions in ldo.c in Lua 5.1 through 5.2.x before 5.2.3 allows context-dependent attackers to cause a denial of service (crash) via a small number of arguments to a f...5.0
