Description
Samba 3.2.x through 3.6.x before 3.6.20, 4.0.x before 4.0.11, and 4.1.x before 4.1.1, 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).
