memcpy (mybuf, buf, len );}In the above example, the if statement at [1] does not seem to be a problem, but len is a signed int, while memcpy requires a size_t len, that is, an unsigned type. As a result, len will be promoted to unsigned. At this time, if we pass len a negative number, it will pass the if check, but will be upgraded to a positive number in memcpy, so our mybuf is overflow. This will cause the dat
