Abstract

This thesis proposes a method for effectively detecting memory errors with low occurrence frequency that may occur depending on runtime situation by analyzing assembly codes obtained by disassembling an executable file. When applying the proposed method to various programs having no compilation error, a total of about 750 potential errors taken about 90 seconds are detected among 1 million lines of assembly codes corresponding to a total of about 10 thousand functions.

본 논문에서는 소프트웨어 구동 시 발생 가능한 메모리 오류 중 발생 빈도가 매우 낮은 일부 메모리 오류에 대해 실행 파일을 역어셈블하여 만들어진 어셈블리어의 구문을 분석하여 메모리 오류 가능성을 검출하는 방법을 제안한다. 몇 개의 프로그램을 대상으로 선정하고, 제안한 방법을 이용하여 메모리 오류 가능성을 검출한 결과, 약 만 개의 함수, 백만 라인의 어셈블리어 명령어에서 750여 개의 메모리 오류 가능성을 검출하였고, 검출에 걸린 시간은 총 90초 정도가 소요되었다.
