I've found a bug in OpenSSH.

Don't worry, I'm pretty sure it's not security relevant.

The triggering condition involved using a serial port instead of a TCP socket for client/server communication.

@ryanc huh, openssh supports that? got links to the docs?

[ryanc@infosec.exchange]

@chaos Not directly, but via ProxyCommand.

@ryanc got more info still on how to configure this?

@ryanc ...do I wanna know how you discovered this?
