I found a small bug in QoS handling in the OpenSSH client under specific conditions. It had a big impact on my workflow but wasn’t a complete showstopper and might not have had an obvious impact on the broader user base. I raised an issue on the tracker and within a day I had a test build, a confirmed fix and a note of which release would carry the fix. It was one of the most positive experiences I’ve had reporting a bug, especially for a non-security issue.

I know this comment doesn’t add much to the conversation about this release, but I’m very grateful to Damien (who handled the issue) and the team for the wonderful job they’re doing on such a core piece of software.

Had the same experience with the OpenRewrite lately.

Link or didn't hapen /s

But seriously if feasible, share the issue link. Especially when there's conversation involved, it's different kind of nice (and learning opportunity) reading such thread

> I raised an issue on the tracker

I thought OpenBSD / OpenSSH operate without a tracker and it’s all email distro based.

OpenSSH uses Bugzilla:

* https://www.openssh.org/report.html

> sshd(8): On OS X SDK >= 27, sandboxing is no longer supported as the API we depended upon has been removed and no obvious alternative provided.

It’s what Apple experimented with before they came up with the current entitlements system.

Entitlements are a great system for user applications, but pretty much unusable for OSS system applications as AIUI they need codesigned binaries

They could have designed a system to put the code signature inside Mach-O but they chose not to.

I wouldn’t really say it compares to entitlements

I look forward to seeing if Apple makes any changes in the fork they ship with the OS: https://github.com/apple-oss-distributions/OpenSSH.

"Updated sandbox for privilege-separated pre-authorization sshd process" is listed as a modification to the open-source project, but I suspect this is out-of-date.

I’m confused why they can’t just write a sandbox profile that does the equivalent

Who is "they" ? AFAIK the OpenSSH team focuses on the OpenBSD version and others people/teams use the new releases to create/update a portable version.

So I think it would be up to the team that ports it to Apple, so I think the "Apple Team" is the ones who would worry about sandboxing.

OpenSSH -portable is maintained by the OpenSSH developers, who are also OpenBSD developers.

The big ticket thing here seems to be mitigation of "Crossing The Streams", a CRIME-style compression side channel that relies on the fact that different sessions share LZ77 state:

" * We have seen a number of cases where a security bug identified * by AI tools is subsequently independently discovered by a * different researcher. This suggests that adversaries who do not * report bugs to OSS projects are likely to be able to discover * these bugs too. Given this, the OpenSSH team will, for now, be * making more frequent releases to get bugfixes into users' hands * more quickly rather than batching them until the next planned * release."

They mention a donation link: https://www.openbsd.org/donations.html

I wonder what their funding is like.

It is based upon what the OpenBSD Foundation gets. Last year:

https://www.openbsdfoundation.org/campaign2025.html

Now I am going to call out IBM. Last I checked, IBM uses OpenSSH on AIX, but gives a big fat 0. Microsoft has been consistent in donating a decent amount. And a surprise to me, Meta showed up donating last year, nice. I wish IBM would join the list too. Based upon:

I think this is much healthier approach to AI reports than curl has. But I understand both sides.

OpenSSH don't have the same luxury of being able to ignore potential vulnerabilities.

Curl doesn't ignore vulnerabilities

Really glad to see the rate of security fixes speeding up.
