Buffer Overflow Primer Part 4 (Disassembling Execve)

||||||||||||
Description: Welcome to Part 4 of the Buffer Overflow Primer. If you have not already done so, please start this series by viewing Part 1. The Buffer Overflow Primer requires that you know at least some basic Assembly Language. I have created a series of Assembly Language video tutorials for Hackers here, for those not familiar with the language.
In this video we will look at how to create shellcode for the Execve() syscall. We will first create a C program to spawn a shell using Execve(), then we will disassemble the program to understand how the syscall works and the kind of inputs it expects. We will cover this part in-depth and trace through individual instructions and recreate the program stack before execve() is called. Once the disassembled code has been understood, we will create our own program in assembly to spawn a shell using Execve(). This video is very important for those who want to learn how to convert a complex syscall() into its working assembly language equivalent.

gnalsa on Sun 17 Apr 2011 @AHMZAO I have noticed the same problem. This is caused by using the newer version of BackTrack instead of BT3. |
