【中文导读】quickjs 存在内存破坏、释放后使用、越界访问风险（高危风险）。具体受影响版本、触发条件和修复方案以 NVD/厂商公告为准。 【原始描述】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 resized and len1 become out of bounds. This results in a use-after-free.A second instance occurs in the same function during printing of a map or set objects. The code iterates over ms->records list, but once again, elements could be removed from the list during js_print_value call.
