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).

Security readout for executives and security teams

This issue lets a remote user bypass intended file restrictions on some Samba file shares when alternate data stream support is enabled. It affects older Samba 3.2, 3.6, 4.0, and 4.1 releases before the fixed versions. Business risk is unauthorized file access or policy bypass on legacy SMB services. Exposure is most likely in legacy Samba deployments that enabled vfs_streams_depot or vfs_streams_xattr for Windows alternate data stream compatibility. Modern, patched Samba versions are not indicated as affected in the provided sources. Treat this as a targeted legacy exposure issue, not a current mass-exploitation emergency based on supplied evidence. Prioritize systems still running old Samba with alternate data stream VFS modules enabled, especially where untrusted users can access file shares. Mitigation focus: Upgrade Samba to 3.6.20, 4.0.11, 4.1.1, or later supported vendor packages.; Apply relevant distribution advisories from Ubuntu, Debian, Red Hat, Fedora, SUSE, or Gentoo.; Inventory SMB servers for vfs_streams_depot or vfs_streams_xattr usage..
