[h=4]Supplemental Buffer Overflow Tutorial Series[/h][h=4]Supplemental Buffer Overflow Tutorial Series - Part 1[/h]Description: In this video I introduce the purpose of this series. It is just another look at buffer overflows because practice and repetition make perfect.

[h=4]Supplemental Buffer Overflow Tutorial Series - Part 2[/h]Description: We talk about When and Why a program crashes because of a buffer overflow. We diddle a little in gdb and perl

[h=4]Supplemental Buffer Overflow Tutorial Series - Part 3[/h]Description: In this part of the series we are looking at when the program actually crashes.

[h=4]Supplemental Buffer Overflow Tutorial Series - Part 4[/h]Description: In this video we make a small change to the program which removes the vulnerability.

[h=4]Supplemental Buffer Overflow Tutorial Series - Part 5[/h]Description: In this video we discuss how to find where EIP is overwritten using Binary Reduction (aka Binary Search)

[h=4]Supplemental Buffer Overflow Tutorial Series - Part 6[/h]Description: In this part of the series we find a place to make EIP jump to so that it can execute our own code instead of crashing. We talk about little endian, nop sleds, how to find space in memory, how to use gdb to examine memory.

[h=4]Supplemental Buffer Overflow Tutorial Series - Part 7[/h]Description: Finally we go and find shellcode. We talk about how shellcode corresponds to byte code and where to find it.

[h=4]Supplemental Buffer Overflow Tutorial Series - Part 8[/h]Description: We wrap up our buffer overflow exploit and make it execute a shell for us. We also recap what happened to spawn the shell code and some of the implications. I introduce the Corelan tutorial serieis aswell.
