[Bug 696276] [NEW] root user can mount a user encrypted directory

 

*** This bug is a security vulnerability ***

Private security bug reported:

I could do that adding a SSH key to the user's authorized_keys file and
login with that key. I am surprise about I could decrypt the user's home
directory!

Doesn't  eCryptfs prevent the root user to mount a user's home
directory?

Thanks!
