Though a compiler checks memory errors, it is difficult for the compiler to detect function pointer errors in code level. Thus, in this paper, we propose a method for effectively detecting Invalid function pointer access errors, by analyzing assembly codes that are obtained by disassembling an executable file. To detect the errors, assembly codes in disassembled files are checked out based on the instruction transition diagrams which are constructed through analyzing normal usage patterns of function pointer access. When applying the proposed method to various programs having no compilation error, a total of about 500 potential errors including the ones of well-known open source programs such as Apache web server and PHP script interpreter are detected among 1 million lines of assembly codes corresponding to a total of about 10 thousand functions.

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.
