在“stack-buffer-overflow on address”这个短语中,“on address”指的是溢出发生时的具体内存地址。当栈缓冲区溢出时,会覆盖某个特定的内存地址,这个地址就是“on address”所指的。了解这个地址有助于调试和分析溢出发生的原因。 可能导致栈缓冲区溢出的示例代码 以下是一个简单的C语言示例,展示了可能导致栈缓冲...

系统在此应用程序中检测到基于堆栈的缓冲区溢出错误。这是一个常见的编程错误，可能会导致程序崩溃或执行非法操作。下面进行详细解释。解释如下：一、堆栈缓冲区溢出的基本概念 堆栈缓冲区溢出是指程序在运行过程中，由于操作不当导致数据超出了为其分配的堆栈内存空间，从而覆盖相邻内存区域的一种错误。这种...

In software, a stack buffer overflow occurs when a program writes to a memory address on the program's call stack outside of the intended data structure; usually a fixed length buffer. Stack buffer overflow bugs are caused when a program writes more data to a buffer located on the stack...

理解MSVC x64 反汇编中为函数调用分配的 stack 大小, 需要了解 microsoft x64 calling convention 使用Address Sanitizer 一方面准确定位问题, 另一方面辅助验证了我们对于 stack buffer size 的计算 最后, 善用namespace, 可以避免相当一部分 ODRV 的问题或风险,推荐使用。 6. References /RTC (Run-time error chec...
