Discover deeper bugs with dynamic symbolic execution and coverage-based fuzz testing

Vitaly Chipounov, George Candea, Bin Zhang, Chao Feng

Coverage-based fuzz testing and dynamic symbolic execution are both popular program testing techniques. However, on their own, both techniques suffer from scalability problems when considering the complexity of modern software. Hybrid testing methods attem ...

Lightweight Snapshots and System-level Backtracking

Vitaly Chipounov, George Candea, Edouard Bugnion

We propose a new system-level abstraction, the lightweight immutable execution snapshot, which combines the immutable characteristics of checkpoints with the direct integration into the virtual memory subsystem of standard mutable address spaces. The abstr ...

Enabling Sophisticated Analysis of x86 Binaries with RevGen

Vitaly Chipounov, George Candea

Current state-of-the-art static analysis tools for binary software operate on ad-hoc intermediate representations (IR) of the machine code. Therefore, even though IRs facilitate program analysis by abstracting away the source language, it is hard to reuse ...

Reverse Engineering of Binary Device Drivers with RevNIC

Vitaly Chipounov, George Candea

This paper presents a technique that helps automate the reverse engineering of device drivers. It takes a closed-source binary driver, automatically reverse engineers the driver’s logic, and synthesizes new device driver code that implements the exact same ...

Selective Symbolic Execution

Vitaly Chipounov, George Candea, Cristian Zamfir

Symbolic execution is a powerful technique for analyzing program behavior, finding bugs, and generating tests, but suffers from severely limited scalability: the largest programs that can be symbolically executed today are on the order of thousands of line ...

Reverse-Engineering Drivers for Safety and Portability

Vitaly Chipounov, George Candea

Device drivers today lack two important properties: guaranteed safety and cross-platform portability. We present an approach to incrementally achieving these properties in drivers, without requiring any changes in the drivers or operating system kernels. W ...
