PathArmor is the first practical Context-sensitive Control-Flow Integrity (CFI) platform. Related work demonstrates that prior CFI implementations, which track control transfers individually, still leave sufficient leeway for powerful ROP attacks. Context-sensitive CFI improves security by validating control transfers to sensitive program states within the context of preceding edges, greatly reducing the number of exploitable program paths available to an attacker.
PathArmor is available open-source at https://github.com/vusec/patharmor.
