Usenix Security 14 Enforcing Forward Edge Control Flow Integrity In Gcc Llvm

Enforcing Forward Edge Control Flow Integrity In Gcc Llvm 氷 菓 Ch can help find forward edge control flow vulnerabilities. these cfi implemen tations are fully integrated into their respective compil ers and were de eloped in collaboration with their open source communities. they do not restrict compiler opti mizations, operation modes, or features.

Enforcing Forward Edge Control Flow Integrity In Gcc Llvm 氷 菓 Clang includes an implementation of a number of control flow integrity (cfi) schemes, which are designed to abort the program upon detecting certain forms of undefined behavior that can potentially allow attackers to subvert the program’s control flow. In this paper, we present implementations of two mechanisms that provide forward edge cfi protection, one in llvm and one in gcc. we also provide a dynamic cfi analysis tool for llvm which can help find forwardedge control flow vulnerabilities. Forward edges can be protected using control flow integrity (cfi) but, to date, cfi implementations have been research prototypes, based on impractical assumptions or ad hoc, heuristic techniques. This paper presents implementations of fine grained, forward edge cfi enforcement and analysis for gcc and llvm that meet the above requirements.

In this paper, we present implementations of two mech anisms that provide forward edge cfi protection, one in llvm and one in gcc. we also provide a dynamic cfi analysis tool for llvm which can help find forward edge control flow vulnerabilities. In this paper, we propose “bgcfi”, which is a fine grained cfi based on a bipartite graph. the relationship between an indirect branch and a valid target address at the branch is represented by an. In this paper, we present llvm cfi, a static source code analysis framework for analyzing state of the art static cfi protections based on the clang llvm compiler framework. llvm cfi works by precisely modeling a cfi policy and then evaluating it within a unified approach. To cope with this issue, the authors present three tools, two of which harden the output binary and the third one is a tool for developers to prevent vulnerabilities. they implemented a c vtable veri cation for gcc, an indirect function call checker for llvm and an addition to llvm's ubsan.
