Funny, I reported something similar on the rsync mailing list a couple of months ago: https://www.mail-archive.com/rsync@lists.samba.org/msg33452....

Good to see that it will be fixed. Still, rsync is not the right tool for the job if you do not trust the server.

I take it that "server" in this context includes the remote party in a "serverless" transfer. I mean, I take it this isn't particular to the rsync daemon.

It sounds like a very serious defect, very easy to exploit. It needed to be addressed quickly. I'm not surprised they skipped the code review.

Why would you ever trust the server not to do bad things?

I do trust my own server not to misbehave, but I probably would not trust some random server on the internet.

I've had personal servers compromised. I don't unconditionally trust them either.

Exactly. I'm usually worried about the opposite scenario (the client infecting the server). If you're copying files from a personal computer it might have all sorts of random software running on it that's accumulated over the years. Whereas on a remote server you tend to have a better security posture, and aren't installing random software and apps. Admittedly, that might just be my personal use case though.

Or if you can't stand mail-archive.com:
