Small security bug with misconfigured access rights

[Giuliano Pochini]

Well, I don't know if it is really a bug.

Create a directory like this:

# ls -la
total 12
drwxr-sr-x   2 pochini  root         4096 Nov 28 16:33 .
drwxr-xr-x  32 pochini  users        8192 Nov 28 16:25 ..

Sgid bit is set and the directory is owned by me and the
group is root (yes, it shouldn't be).

When I create a file here, it gets the root group even
if I don't belong to it.

Bye.
