Stamp-free out-of-the-box has an application-layer for jamming the buffer overflow attack messages targeting at various Internet services. Focus on buffer overflow attacks whose payloads contain executable code in machine language. Unlike the previous code detection algorithms, StpFree uses a new data-flow analysis technique called code abstraction that is generic, fast and hard for exploit code to evade. StpFree is stamp free, thus it can block new and unknown buffer overflow attacks; StpFree is also immunized from most attack-side code obfuscation methods.
