The principle of exploiting a buffer overflow is to overwrite parts of memory which aren't supposed to be overwritten by arbitrary input and making the process execute this code. To see how and where an overflow takes place, lets take a look at how memory ... You will NOT be able to use this tutorial on Windows or Macintosh.

Now we move it along until we figure out where eip lives in the overflow (which is right after ebp in this arch architecture). With that known fact we only have to add 4 more bytes to our buffer of 'A''s and we will overwrite eip completely.

We will use a simple python script combined with Netcat to investigate the buffer overflow condition. buffer = 'HEAD / ' + '\x41' * 256 +'\r\n' print buffer; We execute the script, and pipe it to localhost , port 80 via Netcat:

Introduction ~~~~~~~~~~~~ Over the last few months there has been a large increase of buffer overflow vulnerabilities being both discovered and exploited. Examples of these are ... So a buffer overflow allows us to change the return address of a function. In this way we can change the flow of execution of the program.

The reason for writing this tutorial is that students sometimes ask the following questions when we are discussing the basics of buffer overflows: "Surely, ... First, we overflow the buffer to make the program send us a stack address (the saved EBP value). We then use this address to calculate the location of buf.
