Abstract(in English)	This paper presents a protection scheme to prevent buffer overflow attacks that bypass the NXbit protection and execute arbitary binary code. In order to prevent unauthorized change of memory protection attributes by chained return-into-libc attacks, we restrict system calls that may drop the NXbit(execute permission) of memory pages. We also restrict system calls that may allow files to be executed or mapped into memory with execute permission to prevent attacks that execute injected binary code by way of files.
