hi everyone

Parazyd just caught my attention with this interesting story, to be
added to the history of catastrophies we dodged. I hope someone keeps
a list of systemd CVEs somewhere?

"
Before version 237, the systemd-tmpfiles program will change the
permissions and ownership of hard links. If the administrator disables
the fs.protected_hardlinks sysctl, then an attacker can create hard
links to sensitive files and subvert systemd-tmpfiles, particularly
with "Z" type entries.

...meanwhile I heard from people back from FOSDEM that Mr.Poettering
went on to rewrite rsync :^D

ciao
