PathArmor

Project Description

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.
