Description of the new feature/enhancement

https://www.microsoft.com/security/blog/2020/09/15/microsoft-onefuzz-framework-open-source-developer-tool-fix-bugs/

What was once attached—at great expense—can now be baked into continuous build systems through:

Crash detection, once attached via tools such as Electric Fence, can be baked in with asan.
Coverage tracking, once attached via tools such as iDNA, Dynamo Rio, and Pin can be baked in with sancov.
Input harnessing, once accomplished via custom I/O harnesses, can be baked in with libfuzzer’s LLVMFuzzerTestOneInput function prototype.

Proposed technical implementation details (optional)

It's already being used internally by Windows. As this is a MS project, this should be able to be easily adopted. Source code will be published at https://github.com/microsoft/onefuzz during CppCon 2020.

Thanks for looking out for us! We're already engaged with this team internally. 😄 I'm gonna close this one out until our/their investigation comes to a close.

Great, hope we'll see it show up in the public repo. It'll be interesting to see what it shows for the Console.

You may be happy to know we've already got a fuzzer for our whole VT stack. That's one of the biggest/most important targets, since all application output goes through it.

Yes, I'm hoping/thinking the OneFuzz will replace those.

Based on our discussions with them, their work will build on our existing test cases but replace the fuzzing driver.
