If the requested transfer exceeds the limit then a relative get operation throws a BufferUnderflowException and a relative put operation throws a BufferOverflowException ; in either case, no data is transferred. Absolute operations take an explicit element index and do not affect the position. ...
Meanwhile, values keep arriving into the buffer: the2, the3, the4, the5… But now the buffer is full (because it only holds four values), and the6arrives. That’s an overflow. We have told the buffer to.dropNewest, so the6is thrown away. And so on for the7, the8, and all ...
相对操作里,get操作可能抛出BufferUnderflowException;put操作可能抛出BufferOverflowException。 绝对操作。不根据position成员,而是根据该方法的一个参数作为索引,然后根据这个索引get或put,不会改变position。可能抛出IndexOutOfBoundsException。4|0mark和reset上面还有一个成员mark没讲,它是用来标记位置的。当mark被调用时,...

not open correctly. As it was, this would not be releasable as that’s where our users changes their currently selected account, which is a core part of our application. If you’re unaware of gestural navigation or missed out on testing this, it’s worth double checking that you’re on...

How we ship code, delight customers, and build a team where engineers flourish. The Overflow blog covers all the latest work and learnings from Buffer’s engineering team.

In this tutorial I am going to focus exclusively on the practical skills needed to exploit buffer overflows, and I won't go into any uneccessary details on the theory of how they work, or how buffer overflows can be discovered. There are many other resources available on buffer overflow ...
However if the user exits abnormally (as in a buffer-overflow attack), its euid stays as root even after exiting. To defend against this, a set-root-uid shell program usually drops its root privilege before starting a shell if the executing process is only an effective (but not real) roo...
