Security-Related Bug in Ubuntu 7.10

Create a ‘Shared’ folder in /home/username
Create a ‘Shared 192.168.1.100’ folder in /home/username

Right click ‘Shared’ and go to ‘Share Folder’. Add a NFS share with no allowed IP addresses.
Right click ‘Shared 192.168.1.100’. Add a NFS share with no allowed IP addresses.

Go to ‘System’ – ‘Administration’ – ‘Shared Folders’

You will now see only one share, ‘/home/will/Shared’, that allows 192.168.1.100 to access this folder.

This does change the /etc/exports file, and I believe it may be a security vulnerability.

Doing this with a folder with three words (two spaces) adds each word after the space to hosts allowed to access (read-only) the share.

Seems like it would be important for users to share a folder with spaces in it, especially for everyday desktop use.
