I'm just learning Unix and noticed my Calibre Library is set to drwxrwxrwx.
I read that changing it's permissions will cause errors. I always add reputable files to the database, but it seems like a bad idea to have a database with open permissions.
Do I have any basis to worry about?

    I don't know what Calibre is, but the accessibility of a directory also depends on the permissions of the directories above it, of its parent directories. – Kusalananda Mar 22 '18 at 9:24
  • it's complex to answer that, it depend of so much parameter and how much people want to hack you. Having a folder with rwx is not bad nor good, it really depend. In this case I would say it's kinda OK – Kiwy Mar 22 '18 at 9:30

Being world-writable implies that any local user or process could fill up that partition with large files or large numbers of files, making that partition unusable for anything/anyone else. If Calibre's Library sits on its own partition, the damage is limited; you have only one root partition, the scope of the damage increases.

I don't use Calibre, but if it was my system, I'd start by removing the world-writable bits.
