Some of the well-known Internet worms, including Code Red, Slapper and Slammer, use buffer overflow attacks to propagate and execute payloads. Buffer overflow vulnerabilities are some of the most common programming errors. The CVE vulnerability database indicates that 22% of all vulnerabilities uncov...
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 ...

3.3. Preventing Buffer Overflows Problem C and C++ do not perform array bounds checking, which turns out to be a security-critical issue, particularly in handling strings. The risks increase even … - Selection from Secure Programming Cookbook for C and
The first thing you need to learn in order to proceed with this tutorial is how to attach to your vulnerable program in a debugger. This is essential when developing an buffer overflow exploit, as it allows us to see what is going on inside the application during the crash that allows a...
However, these tools both require the active involvement of the developer, meaning not all programs use them. Systemic protections that strive to make buffer overflows less dangerous when they do occur can protect a much greater variety of software. In recognition of this, operating system and co...

The first thing you need to learn in order to proceed with this tutorial is how to attach to your vulnerable program in a debugger. This is essential when developing an buffer overflow exploit, as it allows us to see what is going on inside the application during the crash that allows a...
Improved buffer overflow protection for a computer function call stack is provided by placing a predetermined ShadowKEY value on a function's call stack frame and copying the ShadowKEY, a caller EBP,
The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application. Stack-based buffer overrun (or stack-based buffer overflow) is a bug that indicates that a program writes more data to a...
