Abstract: A memory alignment randomization method of a memory heap exploit is provided, memory alignment of objects inside a heap area is randomly performed to mitigate the exploits of the vulnerability of the software memory heap area The heap exploit is powerfully mitigated by aligning randomly obtained memory addresses instead of aligning memory addresses at multiples of 4 or 8 when the memory alignment for the objects inside the heap area.
