A stack overflow is a type ofbuffer overflowerror that occurs when a computer program tries to use more memory space in the call stack than has been allocated to that stack. The call stack, also referred to as the stack segment, is a fixed-sizedbufferthat stores local function variables and...
The stack overflow problem is not as prevalent on the newer operating systems, however, because of the small footprint on mobile devices it can become challenging. If your operating system on your mobile device is giving you a stack overflow error, you may have too many apps running. You ...
Conceptually, a stack is just that … a stack of information. You can put things on the stack, and take things off of the stack. It sounds kinda useless, but you’ll have to trust me that it’s fundamental and incredibly useful on microprocessors. Each program running has it’s own st...
yes, a stack is extremely useful for checking balanced parentheses. you can push each opening parenthesis onto the stack, and when you encounter a closing parenthesis, you pop the stack. if the stack is empty when you're done, the parentheses are balanced. when would a stack overflow occur...
Buffer overflow is a kind of exception specific to the field of computing. A buffer overflow occurs when a program attempts to put more data into a buffer, exceeding the capacity of the buffer. As a result, the data overflows from the allocated memory of the buffer and overwrites the data...

Structured exception handling overwrite protection (SEHOP): Attackers may look to overwrite the structured exception handling (SEH), which is a built-in system that manages hardware and software exceptions. They do this through a stack-based overflow attack to overwrite the exception registration record...
and software exceptions. It thus prevents an attacker from being able to make use of the SEH overwrite exploitation technique. At a functional level, an SEH overwrite is achieved using a stack-based buffer overflow to overwrite an exception registration record, stored on a thread’s stack. ...
the exception handler chosen is said to "catch" the exception. If the runtime system cannot find an appropriate exception handler even after searching through the entire call stack, the operating system generates a fatal exception message, which means that the program must close and perhaps the ...
As the other guys have already mentioned, ArrayIndexOutOfBoundsException is an Exception that occurs when you are trying to access an array using an incorrect index. This could be caused by a very simple bug in programming logic. StackOverflowError is something more low-level. It has nothing ...
