SaBRe: load-time selective binary rewriting

Abstract Binary rewriting consists in disassembling a program to modify its instructions. However, existing solutions suffer from shortcomings terms of soundness and performance. We present SaBRe , load-time system for selective binary rewriting. rewrites specific constructs—particularly calls functions—when the is loaded into memory, intercepts them using plugins through simple API. also discuss theoretical underpinnings developed two backends—for —which were used implement three plugins: fast call tracer, multi-version executor, fault injector. Our evaluation shows that imposes little overhead, typically below 3%.
