EECS 213, Spring 2015 Buflab: Buffer Overflow Exploits …

WebOverview. This assignment helps you develop a detailed understanding of the calling stack organization on an x86-64 processor. It involves applying a series of buffer overflow attacks on an executable file called bufbomb. (For some reason, the textbook authors have a penchant for pyrotechnics.) WebBUFBOMB in several different ways: 1. You can set up a series of pipes to pass the string through HEX2RAW. unix> cat exploit.txt ./hex2raw ./bufbomb -t bovik 2. You can store the raw string in a file and use I/O redirection to supply it to BUFBOMB: unix> ./hex2raw < exploit.txt > exploit-raw.txt unix> ./bufbomb -t bovik < exploit-raw.txt smsf warehouse

15-213, Fall 2010 Lab Assignment L3: The Buffer Bomb …

Webused to compile bufbomb. You will need to pad the beginning of your exploit string with the proper number of bytes to overwrite the return pointer. The values of these bytes can be arbitrary. Level 1: Sparkler (5 additional pts) Within the file bufbomb there is also a function fizz having the following C code: void fizz(int val) Web1. You can use a pipe to pass the string through sendstringand feed it directly to bufbomb: unix>./sendstring < exploit.txt ./bufbomb -t bovik 2. You can store the raw string in a file and use I/O redirection to supply it to bufbomb: unix>./sendstring < exploit.txt > exploit-raw.txt unix>./bufbomb -t bovik < exploit-raw.txt WebYou can store the raw string in a file and use I/O redirection to supply it to bufbomb: unix> ./hex2raw < exploit.txt > exploit-raw.txt unix> ./bufbomb -u bovik < exploit-raw.txt; This second approach can also be used when running bufbomb from within gdb: unix> gdb bufbomb (gdb) run -u bovik < exploit-raw.txt smsf verification
