I’ve discovered 4 important security vulnerabilities in OpenVPN. Interestingly, these were not found by the two recently completed audits of OpenVPN code. Below you’ll find mostly technical information about the vulnerabilities and about how  I found them, but also some commentary on why commissioning code audits isn’t always the best way to find vulnerabilities.
