Although the buffer overflow in our example causes the program to crash, this may not always be the case. For example, a buffer overflow may overwrite the return address in the stack. Therefore, the program jumps to the location specified by the new return address. This might lead to execut...
Here's the reason. When you first start the copy operation, the copy buffer is empty. Therefore, there is plenty of room in the buffer to move the files into. But the buffer then fills up, because the files don't move out of the buffer as fast as they are moving in. How can I ...
To access data on a disk, the Linux kernel uses the system of layers shown in Figure 4-2. The SCSI subsystem and everything else described in 3.6 In-Depth: SCSI and the Linux Kernel are represented by a single box. (Notice that you can work with the disk through the filesystem as w...
The original data in the buffer includes the exploited function's return pointer -- the address to which the process should go next. However, the attacker can set new values to point to an address of their choosing. The attacker usually sets the new values to a location where theexploitpayl...
One way to reduce input lag when using VSYNC is to enable "triple buffering" if your graphics card supports it. This essentially adds an extra buffer between your graphics card and monitor, which can help reduce the delay between when you move your mouse or press a key and when the actio...
what is an input buffer? an input buffer is a temporary storage area used in computing to hold data being received from an input device, such as a keyboard or a mouse. it allows the system to receive and process input at its own pace, rather than being dependent on the speed at which...
Okay, it wastes a slot to distinguish between full and empty; however this isn't a safety issue. And it looks just as careful as the other side. It looks like this queue was coded very carefully. There are no clear buffer overflows. On x86 in fact, it's pretty much correct1---if...
Introduction to Shell Scripts(第 11 章 Shell 脚本简介 Shell 脚本简介) If you can enter commands into the shell, you can write shell scripts (also known as Bourne shell scripts). A shell script is a series of commands written in a file; the shell reads the commands from the file just ...
I was looking for a tutorial/book that would teach me how to start to use FFmpeg as a library (a.k.a. libav) and then I found the "How to write a video player in less than 1k lines" tutorial. Unfortunately it was deprecated, so I decided to write this one....
