An example is the errno used by many functions of the c library On a modern machine, where multiple threads may be modifying the errno variable, a call of a system function on one thread may overwrite the value previously set by a call of a system function on a different thread, possibly before following code on that different thread could. 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. In programming and information security, a buffer overflow or buffer overrun is an anomaly whereby a program writes data to a buffer beyond the buffer's allocated memory, overwriting adjacent memory locations.
Stack buffer overflow is a type of the more general programming malfunction known as buffer overflow (or buffer overrun) [1] overfilling a buffer on the stack is more likely to derail program execution than overfilling a buffer on the heap because the stack contains the return addresses for all active function calls. Winpdb debugging itself a debugger is a computer program used to test and debug other programs (the target programs) Common features of debuggers include the ability to run or halt the target program using breakpoints, step through code line by line, and display or modify the contents of memory, cpu registers, and stack frames The code to be examined might alternatively be running on an. Segmentation faults can also occur independently of page faults
