Graphics Card Based Fuzzing

Fuzzing is the art of creating data and using that generated data as input for a target program. The goal behind this is to crash the program in a manner that can be analyzed and exploited. Software developers are able to benefit from fuzzers, as they can patch the discovered vulnerabilities before an attacker exploits them. Programs are becoming larger and require improved fuzzers to keep up with the increased attack surface. Most innovations in fuzzer development are software related and provide better path coverage or data generation. This paper proposes creating a fuzzer that is designed to utilize a dedicated graphics card's graphics processing unit (GPU) instead of the standard processor. Much of the code within the fuzzer is parallelizable, meaning the graphics card could potentially process it in a much more efficient manner. The effectiveness of GPU fuzzing is assessed herein.
