PACSafe uses pointer signatures to retrofit full memory safety to C/C++ programs, protecting heap, stack, and globals against temporal and spatial vulnerabilities. We present a full, LLVM-based prototype implementation, running on an M1 MacBook Pro, i.e., on actual ARMv8.3 hardware. Our prototype evaluation shows that the system outperforms similar approaches under real-world conditions. This, together with its compatibility with uninstrumented libraries and cryptographic protection against attacks on…</p><p><a href="https://hackerpaper.kaipfister.de/p/2202.08669/">Paper and discussion history</a>.
