Abstract
Disclosed herein is a method for detecting a security vulnerability of dynamic memory. The method includes allocating a heap area in physical memory in response to a heap allocation request from a user, allocating a heap area of virtual memory corresponding to the heap area in the physical memory, and returning a heap allocation address to the user, and the heap allocation address includes heap authentication information, heap allocation address identification information, and heap size information.
Claims20
A method for detecting a security vulnerability of dynamic memory, comprising:
- allocating a heap area in physical memory in response to a heap allocation request from a user;
- allocating a heap area of virtual memory corresponding to the heap area in the physical memory;
- and
- returning a heap allocation address to the user,
- wherein the heap allocation address includes heap authentication information, heap allocation address identification information, and heap size information.
An apparatus for detecting a security vulnerability of dynamic memory, comprising:
- a physical memory management unit for allocating a heap area in physical memory in response to a heap allocation request from a user;
- a virtual memory management unit for allocating a heap area of virtual memory corresponding to the heap area in the physical memory;
- and
- an address return unit for returning a heap allocation address to the user,
- wherein the heap allocation address includes heap authentication information, heap allocation address identification information, and heap size information.
