A crafted JavaScript input executed with the QuickJS release 2025-09-13, fixed in commit fcd33c1afa7b3028531f53cd1190a3877454f6b3 (2025-12-11),qjs interpreter using the -m option and a low memory limit can cause an out-of-memory condition followed by an assertion failure in JS_Fr...
A crafted JavaScript input can trigger an internal assertion failure in QuickJS release 2025-09-13, fixed in commit 1dbba8a88eaa40d15a8a9b70bb1a0b8fb5b552e6 (2025-12-11), in file gc_decref_child in quickjs.c, when executed with the qjs interpreter using the -m option. This leads...
A vulnerability exists in the QuickJS engine's BigInt string parsing logic (js_bigint_from_string) when attempting to create a BigInt from a string with an excessively large number of digits. The function calculates the necessary number of bits (n_bits) required to store the BigI...
An integer overflow vulnerability exists in the QuickJS regular expression engine (libregexp) due to an inconsistent representation of the bytecode buffer size. The regular expression bytecode is stored in a DynBuf structure, which correctly uses a $\text{size}_\text{t}$ (an unsi...
A type confusion vulnerability exists in the handling of the string addition (+) operation within the QuickJS engine. The code first checks if the left-hand operand is a string. It then attempts to convert the right-hand operand to a primitive value using JS_ToPrimitiveFree. This...
A vulnerability exists in the QuickJS engine's BigInt string conversion logic (js_bigint_to_string1) due to an incorrect calculation of the required number of digits, which in turn leads to reading memory past the allocated BigInt structure. The function determines the number of...
A vulnerability stemming from floating-point arithmetic precision errors exists in the QuickJS engine's implementation of TypedArray.prototype.indexOf() when a negative fromIndex argument is supplied. The fromIndex argument (read as a double variable, $d$) is used to calculate th...
A Use-After-Free (UAF) vulnerability exists in the QuickJS engine's standard library when iterating over the global list of unhandled rejected promises (ts->rejected_promise_list). The function js_std_promise_rejection_check attempts to iterate over the rejected_promise_list to r...
In quickjs, in js_print_object, when printing an array, the function first fetches the array length and then loops over it. The issue is, printing a value is not side-effect free. An attacker-defined callback could run during js_print_value, during which the array could get resiz...
quickjs-ng through 0.9.0 has an incorrect size calculation in JS_ReadBigInt for a BigInt, leading to a heap-based buffer overflow. QuickJS before 2025-04-26 is also affected.
quickjs-ng through 0.9.0 has a missing length check in JS_ReadString for a string, leading to a heap-based buffer overflow. QuickJS before 2025-04-26 is also affected.
QuickJS before 7414e5f has a quickjs.h JS_FreeValueRT use-after-free because of incorrect garbage collection of async functions with closures.
QuickJS before c4cdd61 has a build_for_in_iterator NULL pointer dereference because of an erroneous lexical scope of "this" with eval.
QuickJS commit 2788d71 was discovered to contain a stack-overflow via the component js_proxy_isArray at quickjs.c.
Buffer Overflow vulnerability in quickjs.c in QuickJS, allows remote attackers to cause denial of service. This issue is resolved in the 2020-07-05 release.
