Incremental CFG patching for binary rewriting
Xiaozhu Meng, Weijie Liu · 2021
Binary rewriting has been widely used in software security, software correctness assessment, performance analysis, and debugging. One approach for binary rewriting lifts the binary to IR and then regenerates a new one, which achieves near-to-zero runtime overhead, but relies on several limiting assumptions on binaries to achieve complete binary analysis to perform IR lifting. Another approach patches individual instructions without utilizing any binary analysis, which has great reliability as it does not make assumptions about the binary, but incurs prohibitive runtime overhead.
