The Samba Web Administration Tool (SWAT) in Samba versions 3.0.x to 3.5.9 are affected by a cross-site request forgery.


The Samba Web Administration Tool (SWAT) in Samba versions 3.0.x to 3.5.9 are affected by a cross-site scripting vulnerability.

Please note that SWAT must be enabled in order for these vulnerabilities to be exploitable. By default, SWAT is *not* enabled on a Samba install.

Release Notes Samba 3.5.10

Samba 3.5.9

Release Notes for Samba 3.5.9:
June 14, 2011:

This is the latest stable release of Samba 3.5.

Major enhancements in Samba 3.5.9 include:

  • Sgid bit lost on folder rename bug #7996.
  • ACL can get lost when files are being renamed bug #7987.
  • Respect "allow trusted domains = no" in Winbind bug #6966.
  • Samba now follows Windows behaviour as a kerberos client, requesting a CIFS/ ticket bug #7893.
  • Kerberos authentication fails when security blobsize is greater than 16 kB bug #6911.

New Kerberos behaviour

A new parameter 'client use spnego principal' defaults to 'no' and means Samba will use CIFS/hostname to obtain a kerberos ticket, acting more like Windows when using Kerberos against a CIFS server in smbclient, Winbind and other Samba client tools. This will change which servers we will successfully negotiate Kerberos connections to. This is due to Samba no longer trusting a server-provided hint which is not available from Windows 2008 or later. For correct operation with all clients, all aliases for a server should be recorded as a as a servicePrincipalName on the server's record in AD.

Release Notes for Samba 3.5.7:
February 28, 2011:

This is a security release in order to address CVE-2011-0719.

All current released versions of Samba are vulnerable to a denial of service caused by memory corruption.

Samba 3.5.5

Release Notes for Samba 3.5.5:
September 14, 2010:

This is a security release in order to address CVE-2010-3069.

All current released versions of Samba are vulnerable to a buffer overrun vulnerability. The sid_parse() function (and related dom_sid_parse() function in the source4 code) do not correctly check their input lengths when reading a binary representation of a Windows SID (Security ID). This allows a malicious client to send a sid that can overflow the stack variable that is being used to store the SID in the Samba smbd server.

Samba 3.5.1

Release Notes for Samba 3.5.1:
March 8, 2010:

This is a security release in order to address CVE-2010-0728.

In Samba releases 3.5.0, 3.4.6 and 3.3.11, new code was added to fix a problem with Linux asynchronous IO handling. This code introduced a bad security flaw on Linux platforms if the binaries were built on Linux platforms with libcap support. The flaw caused all smbd processes to inherit CAP_DAC_OVERRIDE capabilities, allowing all file system access to be allowed even when permissions should have denied access.

(Updated 09-March-2010)

  • Monday, March 8 - Samba 3.5.1 has been released to address CVE-2010-0728.
 Release Notes Samba 3.5.1

Samba 3.5.0

Release Notes for Samba 3.5.0:
March 1, 2010:

This is the first stable release of Samba 3.5.

Major enhancements in Samba 3.5.0 include:

General changes:
  • Add support for full Windows timestamp resolution
  • The Using Samba HTML book has been removed.
  • 'net', 'smbclient' and libsmbclient can use credentials cached by Winbind.
  • The default value of "wide links" has been changed to "no".
Protocol changes:
  • Experimental implementation of SMB2
Printing Changes:
  • Add encryption support for connections to a CUPS server
Winbind changes:
  • Major refactoring
  • Asynchronous
VFS modules:
  • New vfs_scannedonly module has been added.


General changes:

Support for full Windows timestamp resolution has been added. This effectively makes us use Windows' full 100ns timestamp resolution if supported by the kernel (2.6.22 and higher) and the glibc (2.6 and higher).

The Using Samba HTML book has been removed from the Samba tarball. It is still available at http://www.samba.org/samba/docs/using_samba/toc.html.

Samba client tools like 'net', 'smbclient' and libsmbclient can use the user credentials cached by Winbind at logon time. This is very useful e.g. when connecting to a Samba server using Nautilus without re-entering username and password. This feature is enabled by default and can be disabled per application by setting the LIBSMBCLIENT_NO_CCACHE environment variable.

The default value of "wide links" has been changed to "no" to avoid an insecure default configuration ("wide links = yes" and "unix extensions = yes"). For more details, please see http://www.samba.org/samba/news/symlink_attack.html.


Protocol changes

An EXPERIMENTAL implementation of the SMB2 protocol has been added. SMB2 can be enabled by setting "max protocol = smb2". SMB2 is a new implementation of the SMB protocol used by Windows Vista and higher.

Printing Changes

A new parameter "cups encrypt" has been added to control whether connections to CUPS servers will be encrypted or not. The default is to use unencrypted connections.

Winbind changes

The Winbind daemon has been refactored internally to be asynchronous. The new Winbind will not be blocked by running 'getent group' or 'getent passwd'.

VFS modules

A new VFS module "scannedonly" has been added. This is a filter that talks to an antivirus-engine and stores whether a file is clean or not. Users do only see clean files on their filesystem.


Changes

smb.conf changes

  Parameter Name                      Description     Default
  --------------                      -----------     -------

  ctdb timeout			       New	       0
  cups encrypt			       New	       no
  debug hires timestamp	       Changed Default yes
  ldap deref			       New	       auto
  ldap follow referral		       New	       auto
  nmbd bind explicit broadcast	       New	       no
  wide links			       Changed Default no

New configure options

--enable-external-libtdb	Enable external tdb
--enable-netapi			Turn on netapi support
--enable-pthreadpool		Enable pthreads pool helper support
--with-cifsumount		Include umount.cifs (Linux only) support
