Abstract
Applications are protected from being exposed to exploits and instabilities due to memory operations involving zero byte allocations. Memory operations involving a zero byte allocation are handled by a zero byte memory manager. When an application requests a zero byte allocation, a pointer to a protected part of memory is returned such that when the application attempts to read and/or write to the location the program flow is interrupted.
