LuaJIT through 2.1 and OpenRusty luajit2 before v2.1-20240314 have an out-of-bounds read in the stack-overflow handler in lj_state.c.

LuaJIT through 2.1 and OpenRusty luajit2 before v2.1-20240314 have an unsinking of IR_FSTORE for NULL metatable, which leads to Denial of Service (DoS).

LuaJIT through 2.1 and OpenRusty luajit2 before v2.1-20240626 have a stack-buffer-overflow in lj_strfmt_wfnum in lj_strfmt_num.c.

In lj_str_hash.c in OpenResty 1.19.3.1 through 1.25.3.1, the string hashing function (used during string interning) allows HashDoS (Hash Denial of Service) attacks. An attacker could cause excessive resource usage during proxy operations via crafted requests, potentially leading to a denial of service with relatively few incoming requests. This vulnerability only exists in the OpenResty fork in the openresty/luajit2 GitHub repository. The LuaJIT/LuaJIT repository.is unaffected.
