LuaJIT

luajit2

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.

CVE-2024-25178 is a critical vulnerability identified in LuaJIT, a Just-In-Time compiler for the Lua programming language widely used to enhance performance in embedded scripting environments. The flaw exists in the stack-overflow handler implemented in lj_state.c, where an out-of-bounds read can occur when the stack overflow condition is triggered. This vulnerability is classified under CWE-125 (Out-of-bounds Read), and it affects all versions of LuaJIT through 2.1 and OpenRusty luajit2 versions prior to v2.1-20240314. The vulnerability allows an unauthenticated attacker to remotely trigger the flaw over the network without any user interaction, leading to a denial-of-service (DoS) condition by crashing the affected process or system component. The CVSS v3.1 base score of 9.1 reflects the critical nature of this vulnerability due to its network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and high availability impact (A:H). Although no public exploits have been reported yet, the ease of exploitation and the critical impact on availability make this a high-priority issue. LuaJIT is embedded in numerous applications and platforms, including network appliances, game engines, and IoT devices, which broadens the attack surface. The lack of available patches at the time of disclosure necessitates immediate risk mitigation strategies to reduce exposure until fixes are released.

CVE-2024-25178: n/a

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).

CVE-2024-25177 is a vulnerability in LuaJIT, a Just-In-Time compiler for the Lua programming language widely used for performance-critical scripting in applications and embedded systems. The flaw arises from an unsinking of the IR_FSTORE instruction when handling a NULL metatable, a condition that leads to improper memory operations. This issue is classified under CWE-476 (NULL Pointer Dereference), which typically results in application crashes or system instability. The vulnerability affects LuaJIT through version 2.1 and OpenRusty luajit2 versions prior to v2.1-20240314. Exploitation requires no privileges or user interaction and can be triggered remotely if the LuaJIT engine processes crafted input or scripts. The consequence is a Denial of Service (DoS), where the affected application or system may crash or become unresponsive, impacting availability but not confidentiality or integrity. The CVSS v3.1 score is 7.5 (high), reflecting the network attack vector, low complexity, no required privileges, and no user interaction. No public exploits have been reported yet, and no official patches are linked, though the fixed version is indicated. The vulnerability's root cause is related to the LuaJIT intermediate representation (IR) optimization phase mishandling NULL metatables, causing unsafe memory operations during JIT compilation or execution.

CVE-2024-25177: n/a

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.

CVE-2024-25176 identifies a critical stack-buffer-overflow vulnerability in LuaJIT, a Just-In-Time compiler for the Lua programming language widely used to improve performance in embedded scripting environments. The vulnerability exists in the lj_strfmt_wfnum function within the lj_strfmt_num.c source file, which is responsible for formatting numeric strings. The flaw allows an attacker to overflow the stack buffer, potentially overwriting adjacent memory and enabling arbitrary code execution. The vulnerability affects LuaJIT versions through 2.1 and OpenRusty luajit2 versions prior to v2.1-20240626. The CVSS 3.1 base score of 9.8 reflects its critical nature, with attack vector being network (AV:N), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality, integrity, and availability all rated high (C:H/I:H/A:H). This means an attacker can exploit the vulnerability remotely without authentication or user interaction, leading to full system compromise. The vulnerability is classified under CWE-121 (Stack-based Buffer Overflow), a common and dangerous class of memory corruption bugs. No patches or exploit code are currently publicly available, but the vulnerability is reserved and published by MITRE, indicating recognition and urgency. Systems embedding LuaJIT for scripting, including web servers, game engines, and IoT devices, are at risk if they use vulnerable versions. Attackers could leverage this flaw to execute arbitrary code, escalate privileges, or cause denial of service. The lack of known exploits in the wild suggests a window for proactive mitigation.
