TOCTOU in mount.ecryptfs_private

Thanks for the report. I'll get this fixed.

Marc, Kees says that you have looked recently at how FUSE handles situations like this. Could you offer any suggestions as to how I could lock the src and dest between the ownership check and the mount/umount?

flock() perhaps?

I'm not the expert on this topic, but for mount, you should be able to:

1- chdir into the mountpoint
2- perform your sanity checks using "."
3- mount using "."

That way, even if the attacker changes symlinks on the path, you should still be in the original directory he specified. If memory serves, that's what mount.cifs now does, so you might want to take a look at it's source.

For umount, newer kernels since 2.6.34 have a UMOUNT_NOFOLLOW flag, or you can use /bin/umount with --no-canonicalize.

Hope this helps.

Neat! Thanks.

Oh, wait. That works for the destination dir. But what about the source dir?

Oh, yeah the source dir can be manipulated also...hmm...I'm not quite sure how to handle that...

Unless you'd prefer one big patch, I'll start uploading fixes for the various issues here one at a time as I write them.

The current list goes something like this (with help from Marc):

1. Race condition when checking mountpoint during mount
2. Race condition when checking mountpoint during unmount
3. Race condition when checking source during mount
4. Improper mtab handling allowing corruption due to resource limits, signals, etc.
5. Key poisoning in ecryptfs-setup-private due to insecure temp directory
6. ecryptfs-recover-private mounts directly in /tmp
7. Predictable lock counter name and associated races

First, I've attached a first pass at doing mtab handling properly. I plan on addressing 1 and 2 next.

Here's a second patch, which I decided to make cumulative. This includes fixes for both race conditions against the mountpoint, which should fix the ability to mount or unmount arbitrary locations. It still includes the fixes for improper mtab handling.

Untested.

Thanks for working on this Dan!

I'll get these reviewed and tested and committed upstream.

I have a fix for the race condition in checking the source during mount as well. I'll test it and hopefully have it ready in the next day or two.

Dustin,

Please consider this issue embargoed. We are planning on coordinating a release date with other distros. Do not check anything upstream until we do. Thanks!

@segooon: If you want to be credited with having independently discovered the issues you opened this bug for, please give me your real name to include in the notification I am going to send other vendors. Thanks!
