16 Release Notes for Samba 4.1.1
18 =============================
21 This is a security release in order to address
22 CVE-2013-4475 (ACLs are not checked on opening an alternate
23 data stream on a file or directory) and
24 CVE-2013-4476 (Private key in key.pem world readable).
27 Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x,
28 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying
29 file or directory ACL when opening an alternate data stream.
31 According to the SMB1 and SMB2+ protocols the ACL on an underlying
32 file or directory should control what access is allowed to alternate
33 data streams that are associated with the file or directory.
35 By default no version of Samba supports alternate data streams
36 on files or directories.
38 Samba can be configured to support alternate data streams by loading
39 either one of two virtual file system modues (VFS) vfs_streams_depot or
40 vfs_streams_xattr supplied with Samba, so this bug only affects Samba
41 servers configured this way.
43 To determine if your server is vulnerable, check for the strings
44 "streams_depot" or "streams_xattr" inside your smb.conf configuration
48 In setups which provide ldap(s) and/or https services, the private
49 key for SSL/TLS encryption might be world readable. This typically
50 happens in active directory domain controller setups.
