Gdbserver is a computer program that makes it possible to remotely debug other programs [1] running on the same system as the program to be debugged, it allows the gnu debugger to connect from another system That is, only the executable to be debugged needs to be resident on the target system (target), while the source code and a copy of the binary file to be debugged reside on the. An example call to the printf function printf is a c standard library function that formats text and writes it to standard output Mismatch between the format specifiers and count and type of values results in undefined behavior and possibly program crash. [1][2] stack buffer overflow bugs are caused when a program writes more data to a buffer located on the stack than what is actually allocated for that buffer
When executed, a variable, s, is set to point to the string's location, and an attempt is made to write an h character through the variable into the memory, causing a segmentation fault. This is a comparison of debuggers Computer programs that are used to test and debug other programs. Ptrace is used by debuggers (such as gdb and dbx), by tracing tools like strace and ltrace, and by code coverage tools Ptrace is also used by specialized programs to patch running programs, to avoid unfixed bugs or to overcome security features. A kernel debugger is a debugger present in some operating system kernels to ease debugging and kernel development by the kernel developers
