$22k awarded to SBFT ‘23 fuzzing competitors winners


Google’s Open Supply Safety Group lately sponsored a fuzzing competitors as a part of ICSE’s Search-Primarily based and Fuzz Testing (SBFT) Workshop. Our objective was to encourage the event of latest fuzzing methods, which might result in the invention of software program vulnerabilities and finally a safer open supply ecosystem. 

The rivals’ fuzzers had been judged on code protection and their means to find bugs: 

Opponents had been evaluated utilizing FuzzBench, Google’s open supply platform for testing and evaluating fuzzers. The platform boasts a variety of actual world benchmarks and vulnerabilities, permitting researchers to check their fuzzers in an genuine surroundings. We hope the outcomes of the SBFT fuzzing competitors will result in extra environment friendly fuzzers and ultimately newly found vulnerabilities. 

Eight groups submitted fuzzers to the ultimate competitors and a further 4 business fuzzers (AFL++, libFuzzer, Honggfuzz, and AFL) had been included as controls to characterize present apply. 

HasteFuzz, is a modification of the extensively used AFL++ fuzzer. HasteFuzz filters out probably duplicate inputs to extend effectivity, making it in a position to cowl extra code within the 23-hour take a look at window as a result of it’s not prone to be retracing its steps. AFL++ is already a powerful fuzzer—it had the most effective code protection of the business fuzzers examined on this competitors—and HasteFuzz’s filtering took it to the following degree.

PASTIS makes use of a number of fuzzing engines that may independently cowl totally different program places, permitting PASTIS to search out bugs shortly. AFLrustrust rewrites AFL++ on high of LibAFL, which is a library of options that permits you to customise current fuzzers. AFLrustrust successfully prunes redundant take a look at circumstances, enhancing its bug discovering effectivity. Each PASTIS and AFLrustrust discovered 8 out of 15 potential bugs, with every fuzzer lacking just one bug found by others. They each outperformed the business fuzzers, which discovered 7 or fewer bugs underneath the identical constraints.

Extra rivals, equivalent to AFL+++ and AFLSmart++, additionally confirmed enhancements over the business controls, a end result we had hoped for with the competitors.

The innovation and enchancment proven by the SBFT fuzzing competitors is one instance of why we’ve got invested within the FuzzBench mission. Since its launch in 2020, FuzzBench has considerably contributed to high-quality fuzzing analysis, conducting over 900 experiments and mentioned in additional than 100 tutorial papers. FuzzBench was supplied as a useful resource for the SBFT competitors, however it is usually obtainable to researchers day-after-day as a service. If you’re taken with testing your fuzzers on FuzzBench, please see our information to including your fuzzer.

FuzzBench is in lively growth. We’d welcome suggestions from any present or potential FuzzBench customers, your responses to this survey can assist us plan the way forward for FuzzBench.

The Google Open Supply Safety Group want to thank the ICSE convention and the SBFT workshop for internet hosting the fuzzing competitors. We additionally wish to thank every participant for his or her onerous work. Collectively, we proceed to push the boundaries of software program safety and create a safer, extra strong open supply ecosystem.
