Sure, see any of the previous exploits for sshd, or any other software shipped in the OpenBSD default install.
> I keep asking this as a long-time OpenBSD user who is genuinely interested in seeing it done, but so far everyone who has said "it's flawed" also reserved themselves the convenience of not having to prove their point in a practical sense.
The point is they have very little in the way of containing attackers and restricting what they can. Until pledge and unveil, almost all their focus in on eliminating bugs which hey, great, but let's have a little more in case you miss a bug and someone breaks in, eh?
An insecure dockerized webserver protected with SELinux is safer than Apache on a default OpenBSD install.
Would you like to point to one that successfully utilizes a weakness in OpenBSD itself, which is the topic and implied statement of the video, rather than a weakness in some application running under the superuser?
Just to underline, I'm not interested in discussing the hows and whys of containing arbitrary applications where one or more portions are running under euid 0. I'm interested in seeing OpenBSD successfully attacked by an unprivileged process/user.
If OpenBSD users installed it through OpenBSD repositories and are running it will they be affected? Yes? Then it counts against the system itself.
I'm sorry, what? What kind of nonsense distinction is this?
Are you trying to very disingenuously try and claim only kernel exploits count as attacks against OpenBSD?
Why the hell wouldn't a webserver zero-day count? If an OS that claims to be security focused can't constrain a misbehaving web server running as root then it's sure as hell not any type of secure OS.

You realize there is very little that OpenBSD does to protect against LPE if there is any LPE vuln on their system, right? Surely you're not just advocating for OpenBSD based on their own marketing? If you want to limit the goalposts to kernel vulns or LPE's that already require an account you're free to do so, but that's rather silly and not remotely indicative of real world security needs.
If it's a security focused OS, it should provide ways to limit the damage an attacker can do. OpenBSD had very very little in that regard and still does, although things are slightly better now and they have a few toys.
And hey, fun fact, if you apply the same OpenBSD methodology and config of having a barebones install, you'll suddenly find at least dozens of other operating systems with equivalent or better track records.
Plan 9 has had less vulnerabilities than OpenBSD and has had more thought put into its security architecture[0], so by your metric it's the more secure OS, yeah?
Not at all. I clearly underlined that I'm not looking for cases fitting that specific scenario. The only moving of goalposts is entirely on your behalf by very disingenously misrepresenting my question in a poor attempt to try make your answer or whatever point fit. And on top of that, the tasteless pretending to be baffled...
