Hi, I'm the librsync (not rsync) maintainer. I can confirm this is a real bug, and I would like a CVE assigned. I appreciate Mik reporting this. Since it's now been discussed in public I don't see any point treating this as embargoed. I'm working on his patch adding BLAKE2 (eg making it pass tests, having an option for back-compatibility) so that it can be released. -m
