You could find a stack buffer overflow bug, use it to overwrite the current call frame's return address on the stack, wait for the exploited function to reach its end and return, thus gaining control over the instruction pointer (IP), which you could point back at instructions you put in...
Before seeking out buffer overflows in code, let’s take a look at what they are in the first place. As the name implies, a buffer overflow is a type of vulnerability that deals with buffers, or memory allocations in languages that offer direct, low-level access to read and write memory...
Python provides a high-level programming interface that abstracts low-level memory management, making buffer overflow less common. However, it is still possible to encounter buffer overflow vulnerabilities in Python, especially when working with low-level modules or extensions. Let’s consider a simple...
I manage to do this with a python script, I run the program in gdb and specify 500 A's to be printed, this seems to work as I then inspect the registers and the instruction pointer is 0x41414141 meaning it's overwritten it with 'A's ...
It depends on what you call buffer overflow. It is possible and easy to make software which never writes outside of a buffer. All it takes is a programming language which checks array bounds, e.g. Python, Java, C#, VB, Pascal, Ruby... in fact almost any language except C,...
Return-oriented Programming ROP is a cutting-edge method for getting around contemporary mitigations. To alter the program’s execution flow, a chain of already-written code sequences known as gadgets must be constructed. ROP is frequently used in conjunction with buffer overflows to enable arbitra...
As you can see, the input buffer is 5 bytes in length (4 data, plus one for the null terminator). The initial value of the int within the structure is set to 10, but after thegets()function has been called, the value has been changed. Go here for more onbuffer overflows and othe...
Meaning that we want to jump to 0x08048558. Anyway, lets first try to see if our 28 'A' are enough to rewrite the saved eip. (gdb) next 10 strcpy(password_buffer, password); (gdb) next 11 if (strcmp(password_buffer, "cup") == 0) { Here, the strcpy did the overflow, so...
