In May I started building fuzzers for OpenVPN because I liked engaging in the challenge of finding more vulnerabilities after two fresh audits. I never intended or expected to receive money for this. In addition to the money donated by people and companies to my Bitcoin address (thank you very much again), OSTIF reached out to me and offered to reward me with a bounty of $5000 for the vulnerabilities and for completing the fuzzers. Thank you so much!
The fuzzers can be found here: https://github.com/guidovranken/openvpn/tree/fuzzing There are still some small portions of code that remain un-fuzzed. I am very busy with contracting work so I won’t be working on it sometime soon. You are welcome to extend it and find more vulnerabilities, and you might be eligible for bounties yourself.
OSTIF is currently running a fundraiser to get OpenSSL 1.1.1 audited. Check it out and spread the word.
