Samba, when vfs_streams_depot or vfs_streams_xattr is enabled, allows
remote attackers to bypass intended file restrictions by leveraging
ACL differences between a file and an associated alternate data stream
(ADS). (CVE-2013-4475)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
