Stack Underflow In general, a Stack Underflow is the opposite of an overflow. You've somehow thought you put more on the stack than you really have and you've popped off too much. You've reached the beginning of the stack and it's empty, but you thought there was more data and kept...
[Windows编程] stack overflow != stack buffer overflow 经常看到有人把2个概念混淆, 其实这2者是有区别的。Windows 中它们的异常代码也是不同的: STATUS_STACK_OVERFLOW (0xc00000fd ) STATUS_STACK_BUFFER_OVERRUN (0xc0000409) 下面这篇文章很好地解释了它们的不同: Stack overflow (stack exhaustion) not...
A stack buffer underflow (writing below the lower bound of a buffer) may overwrite the values of the callee-saved registers, which may also be code or data pointers. An arbitrary out-of-bounds write will either cause the application to crash or behave in an undefined way. However, a ...
