okay, this is a detailed and comprehensive tutorial on buffer overflow vulnerabilities in statically linked and stripped linux binaries. it's going to cover the concepts, techniques, challenges, and protections involved. be warned: exploit development is a complex topic. this tutorial aims to give you a solid foundation, but you'll need to practice and experiment to truly master it.

*disclaimer:* this information is for educational purposes only. do not attempt to exploit vulnerabilities in systems you do not own or have explicit permission to test. unauthorized exploitation is illegal and unethical.

*i. introduction to buffer overflow*

a buffer overflow occurs when a program writes data beyond the allocated boundaries of a buffer in memory. this can overwrite adjacent memory regions, potentially corrupting program data, control flow (e.g., return addresses), or even executing arbitrary code. it's a classic and dangerous vulnerability.

*ii. statically linked binaries: a different landscape*

*definition:* a statically linked binary includes all the necessary library code directly within the executable itself. this means it doesn't rely on shared libraries (.so files) present on the target system.
*implications for exploitation:*
*predictable addresses:* statically linked binaries often have more predictable addresses. libraries, which would normally be loaded at different addresses on different systems, are embedded into the binary at compile-time, creating consistent address mappings. this simplifies address calculations.
*larger size:* statically linked executables are generally much larger than dynamically linked ones.
*no dependencies:* they don't require specific library versions on the target, increasing portability (but also size).
*exploitation opportunities:* this predictability can be useful if the binary includes useful gadgets to use in a return-oriented programming (rop) attack.
