When is a 0day not a 0day? When the exploit ends up being just a poor default configuration issue. It can lead to files being read, that the user has permission to read. Like /etc/passwd for example. The solution? Set "wide links = no" in the [global] section of your smb.conf and restart smbd to eliminate this problem, from the Samba Symlink Attack posting here. Thanks Elazar!
