This is true if a such variable is stored in a CPU register. In these cases, additional measures will be required to prevent this, such as declaring the variable with the volatile modifier. An example (illustration only): volatile HANDLE hFile = NULL; __seh_try { hFile = CreateFile ();
Incase your wondering that stack is just an example, and is not what the stack of our vulnerable program will look like (but you get the idea.) The example below will be based on Windows 2000. 1 – The Target Program Is Fuzzed, Stack Contents Overwritten 2 – Exploitation – [Junk] + [JMP 6 Bytes] + [CALL EBX] + [NOPSLED] + [Shellcode]
Examples are the cor-rectness of the bytecode verifier of CLR, the type (SEH). An interested reader can find all the insights of the SEH in [3]. [4, §4] as a fairly elab-orate model that permits a unified view of exceptions in C++, C], and other high-level languages.So far, no formal model has been developed for the CLR excep-tion
In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program.In general, an exception breaks the normal flow of execution and executes a pre-registered exception handler; the details of how this is done depend on whether it is a Handlers for the Application (Project) Types. Providing Your Own Exception/Termination Handler. Using Windows* Structured Exception Handling (SEH) Custom Handlers for Fortran Console, Fortran QuickWin, and Fortran Standard Graphics Applications. Custom Handlers for Fortran DLL Applications. Custom Handlers for Fortran Windows* Applications.
This is an exception thrown by C++ Builder. Windows SDK These exceptions are Windows exceptions that may or may not be defined in the IDE/SDK that you are using. For more information you can look up error codes and exceptions here and here. Fatal Memory Exhaustion 0xC00001AD STATUS_FATAL_MEMORY_EXHAUSTION
MS Visual C++ compiler features three non-standard keywords: __try, __except and __finally — for this purpose. Other exception handling aspects are backed by a number of Win32 API functions, [2] for example, RaiseException to raise SEH exceptions manually. Implementation [ edit] IA-32 [ edit]

Microsoft made a function which is used to handle exceptions, called the Structured Exception Handler. When doing SEH overwrites the Pointer to the SEH Handler is target to be overwritten so we can gain control over the program. Pointer to Next SEH? The pointer to the next SEH is a pointer to the next Structured Exception Handler on the stack.
This lower-level facility uses two-phase exception handling; in the first, “search” phase the stack is walked from the throw point to identify a suitable handler, while in the second, “unwind” phase it is walked again from the throw point to the selected handler, this time invoking cleanup (i.e., destructors) along the way.
