A method and system for secure dynamic memory management using heap memory, or analogous dynamic memory allocation, that includes initializing a heap memory segment, having a plurality of buffers, within a random access memory. When an allocation request to store data in the heap memory segment is received, one of the buffers is randomly selected. Metadata, containing details of allocated and unallocated buffers of the heap memory segment, is then maintained in a portion of the memory separate from the heap object. According to certain embodiments, the secure heap of the present disclosure can securely implement the functions of those portions of the C/C++ stdlib library related to dynamic memory management, specifically malloc ( ), free ( ) and their variants. |
