MEMORY STABILITY DETERMINATION APPARATUS, METHOD OF DETERMINING STABILITY OF MEMORY ALLOCATION CODE BY DETECTING ATYPICAL MEMORY ALLOCATION CODE, AND COMPUTER PROGRAM

A method of determining stability of a memory allocation code includes inputting, by a memory stability determination apparatus, a program to a classifier and detecting a custom memory allocation code, inserting, by the memory stability determination apparatus, a first function to increase a memory chunk to be allocated by a set size and allocate the memory chunk and a second function to poison an increased region with a garbage value, to a point preceding the custom memory allocation code, runtime executing, by the memory stability determination apparatus, a program into which the first function and the second function are inserted, to detect an access to a poisoned region poisoned with the garbage value, and determining, by the memory stability determination apparatus, that security of the custom memory allocation code is weak when the access to the poisoned region is true (1).
