Center node: "hardscope thwarting dop with hardware assisted run time scope enforcement"
  Abstract: Widespread use of memory unsafe programming languages (e.g., C#R##N#and C++) leaves many systems vulnerable to memory corruption#R##N#attacks. A variety of defenses have been proposed to mitigate attacks#R##N#that exploit memory errors to hijack the control flow of the code#R##N#at run-time, e.g., (fine-grained) randomization or Control Flow Integrity. However, recent work on data-oriented programming (DOP)#R##N#demonstrated highly expressive (Turing-complete) attacks, even in#R##N#the presence of these state-of-the-art defenses. Although multiple#R##N#real-world DOP attacks have been demonstrated, no efficient defenses are yet available. We propose run-time scope enforcement#R##N#(RSE), a novel approach designed to efficiently mitigate all currently#R##N#known DOP attacks by enforcing compile-time memory safety constraints (e.g., variable visibility rules) at run-time. We present HardScope, a proof-of-concept implementation of hardware-assisted#R##N#RSE for the new RISC-V open instruction set architecture. We#R##N#discuss our systematic empirical evaluation of HardScope which#R##N#demonstrates that it can mitigate all currently known DOP attacks,#R##N#and has a real-world performance overhead of 3.2% in embedded#R##N#benchmarks.
