August 1, 2014

This is a security release in order to address

Samba 4.0.0 to 4.1.10 are affected by a remote code execution attack on unauthenticated nmbd NetBIOS name services.
A malicious browser can send packets that may overwrite the heap of the target nmbd NetBIOS name services daemon. It may be possible to use this to generate a remote code execution vulnerability as the superuser (root).

Samba 4.1.9

Release Notes for Samba 4.1.9
June 23, 2014

This is a security release in order to address

All current released versions of Samba are vulnerable to a denial of service on the nmbd NetBIOS name services daemon. A malformed packet can cause the nmbd server to loop the CPU and prevent any further NetBIOS name service.
This flaw is not exploitable beyond causing the code to loop expending CPU resources.
All current released versions of Samba are affected by a denial of service crash involving overwriting memory on an authenticated connection to the smbd file server.

Changes since 4.1.8:

  • Jeremy Allison <jra@samba.org>

Samba 4.1.6

Release Notes for Samba 4.1.6
March 11, 2014

This is a security release in order to address

  • CVE-2013-4496 (Password lockout not enforced for SAMR password changes) and CVE-2013-6442 (smbcacls can remove a file or directory ACL by mistake).
  • CVE-2013-4496: Samba versions 3.4.0 and above allow the administrator to implement locking out Samba accounts after a number of bad password attempts.
However, all released versions of Samba did not implement this check for password changes, such as are available over multiple SAMR and RAP interfaces, allowing password guessing attacks.
  • CVE-2013-6442: Samba versions 4.0.0 and above have a flaw in the smbcacls command. If smbcacls is used with the "-C|--chown name" or "-G|--chgrp name" command options it will remove the existing ACL on the object being modified, leaving the file or directory unprotected.

Samba 4.1.3

Release Notes for Samba 4.1.3
December 9, 2013


This is a security release in order to address

  • CVE-2013-4408 (DCE-RPC fragment length field is incorrectly checked) and
  • CVE-2012-6150 (pam_winbind login without require_membership_of restrictions).
Samba versions 3.4.0 and above (versions 3.4.0 - 3.4.17, 3.5.0 - 3.5.22, 3.6.0 - 3.6.21, 4.0.0 - 4.0.12 and including 4.1.2) are vulnerable to buffer overrun exploits in the client processing of DCE-RPC packets. This is due to incorrect checking of the DCE-RPC fragment length in the client code.
This is a critical vulnerability as the DCE-RPC client code is part of the winbindd authentication and identity mapping daemon, which is commonly configured as part of many server installations (when joined to an Active Directory Domain). A malicious Active Directory Domain Controller or man-in-the-middle attacker impersonating an Active Directory Domain Controller could achieve root-level access by compromising the winbindd process.
Samba server versions 3.4.0 - 3.4.17 and versions 3.5.0 - 3.5.22 are also vulnerable to a denial of service attack (server crash) due to a similar error in the server code of those versions.
Samba server versions 3.6.0 and above (including all 3.6.x versions, all 4.0.x versions and 4.1.x) are not vulnerable to this problem.
In addition range checks were missing on arguments returned from calls to the DCE-RPC functions LookupSids (lsa and samr), LookupNames (lsa and samr) and LookupRids (samr) which could also cause similar problems.
As this was found during an internal audit of the Samba code there are no currently known exploits for this problem (as of December 9th 2013).
Winbind allows for the further restriction of authenticated PAM logins using the require_membership_of parameter. System administrators may specify a list of SIDs or groups for which an authenticated user must be a member of. If an authenticated user does not belong to any of the entries, then login should fail. Invalid group name entries are ignored.
Samba versions 3.3.10, 3.4.3, 3.5.0 and later incorrectly allow login from authenticated users if the require_membership_of parameter specifies only invalid group names.
This is a vulnerability with low impact. All require_membership_of group names must be invalid for this bug to be encountered.


Changes since 4.1.2:

  • Jeremy Allison <jra@samba.org>
  • Stefan Metzmacher <metze@samba.org>

Samba 4.1.1

Release Notes for Samba 4.1.1
November 11, 2013

This is a security release in order to address CVE-2013-4475 (ACLs are not checked on opening an alternate data stream on a file or directory) and CVE-2013-4476 (Private key in key.pem world readable).

Samba versions 3.2.0 and above (all versions of 3.2.x, 3.3.x, 3.4.x, 3.5.x, 3.6.x, 4.0.x and 4.1.x) do not check the underlying file or directory ACL when opening an alternate data stream.
According to the SMB1 and SMB2+ protocols the ACL on an underlying file or directory should control what access is allowed to alternate data streams that are associated with the file or directory.
By default no version of Samba supports alternate data streams on files or directories.
Samba can be configured to support alternate data streams by loading either one of two virtual file system modues (VFS) vfs_streams_depot or vfs_streams_xattr supplied with Samba, so this bug only affects Samba servers configured this way.
To determine if your server is vulnerable, check for the strings "streams_depot" or "streams_xattr" inside your smb.conf configuration file.
In setups which provide ldap(s) and/or https services, the private key for SSL/TLS encryption might be world readable. This typically happens in active directory domain controller setups.

Changes since 4.1.1:

Samba 4.1.0

Release Notes for Samba 4.1.0
October 11, 2013

This is is the first stable release of Samba 4.1.

Samba 4.1 will be the next version of the Samba suite and includes all the technology found in both the Samba4 series and the stable 3.x series. The primary additional features over Samba 3.6 are support for the Active Directory logon protocols used by Windows 2000 and above.

Major enhancements in Samba 4.1.0 include:

Client tools support SMB2/3

Samba 4.1.0 contains the first release of our client tools and client library that work over the new protocols SMB2 or SMB3. Note that SMB3 only works either to a Samba server version 4.0.0 or above, or to a Windows Server running Windows 2012 or Windows 8.

The default protocol for smbclient and smbcacls is still SMB1 (the NT1 protocol dialect). An SMB2 or SMB3 connection can be selected in one of two ways. The easiest way to test the new protocol connection is to add the -mMAX_PROTOCOL command line switch to either smbclient or smbcacls.

For example, to connect using SMB3 with smbclient a user would type:

smbclient //server/share -Uuser%password -mSMB3

Another example of connecting using SMB2 using smbcacls would be:

smbcacls //server/share -Uuser%password -mSMB2 filename

Note that when connecting using SMB2 or SMB3 protocols the UNIX extensions are no longer available inside the smbclient command set. This is due to UNIX extensions not yet being defined for the SMB2 or SMB3 protocols.

The second way to select SMB2 or SMB3 connections is to set the "client max protocol" parameter in the [global] section of your smb.conf.

Setting this parameter will cause all client connections from Samba and its client tools to offer the requested max protocol to a server on every connection request.

For example, to cause all client tools (including winbindd, rpcclient, and the libsmbclient library) to attempt use SMB3 by default add the line:

client max protocol = SMB3

to the [global] section of your smb.conf. This has not been as widely tested as the -mPROTOCOL options, but is intended to work correctly in the final release of 4.1.0.

Samba3/SMB2
Encrypted transport

Although Samba servers have supported encrypted transport connections using the UNIX extensions for many years, selecting SMB3 transport allows encrypted transport connections to Windows servers that support SMB3, as well as Samba servers.

In order to enable this, add the "-e" option to the smbclient command line.

For example, to connect to a Windows 2012 server over SMB3 and select an encrypted transport you would use the following command line:

smbclient //Win2012Server/share -Uuser%password -mSMB3 -e


Directory database replication (AD DC mode)

Directory replication has been reworked in order to improve the correctness and efficiency.

As a net effect of it, replication with other domain controllers with a heavily modified schema is now possible (ie. Windows 2012 DCs or other Windows DC with exchange installed) and replication didn't fail anymore in such environments.

Server-Side Copy Support

Samba 4.1.0 adds support for server-side copy operations via the SMB2 FSCTL_SRV_COPYCHUNK request. Clients making use of server-side copy support, such as Windows Server 2012, should experience considerable performance improvements for file copy operations, as file data need not traverse the network.

This feature is enabled by default on the smbd file server.

Btrfs Filesystem Integration

The Btrfs VFS module provided with Samba 4.1.0 further improves the performance of server-side copy operations on shares backed by a Btrfs filesystem. It does so by allowing multiple files to share the same on-disk extents, avoiding the unnecessary duplication of source and destination file data during a server-side copy operation.

This feature can be explicitly enabled on smbd shares backed by a Btrfs filesystem with the smb.conf parameter:

vfs objects = btrfs
REMOVED COMPONENTS

The Samba Web Administration Tool (SWAT) has been removed. Details why SWAT has been removed can be found on the samba-technical mailing list:
