Nowadays Buffer overflow attacks are still recognized as one of the most severe threats in software security. Previous solutions suffer from limitations in that: 1) Some methods based on compiler extensions have limited practicality because they need to access source code; 2) Other methods that need to modify some aspects of the operating system or hardware require much deployment effort; 3) Almost all methods are unable to deploy a runtime protection for programs that cannot afford to restart. In this paper, we propose PHUKO, an on-the-fly buffer overflow prevention system which leverages virtualization technology. PHUKO offers the protected program a fully transparent environment and an easy deployment without the need to restart the program. The experiments show that our system can defend against realistic buffer overflow attacks effectively with moderate performance overhead.
