+ Release Notes for Samba 3.6.23
+ March 11, 2014
+ ==============================
+
+
+This is a security release in order to address
+CVE-2013-4496 (Password lockout not enforced for SAMR password changes).
+
+o CVE-2013-4496:

+ 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.
+

+===========================================================
+== Subject: CVE-2013-4496: Password lockout not enforced for SAMR password changes
+==
+== CVE ID#: CVE-2013-4496
+==
+== Versions: All versions of Samba later than 3.4.0
+==
+== Summary: In Samba's SAMR server we neglect to ensure that
+== attempted password changes will update the bad password
+== count, nor set the lockout flags.
+== This would allow a user unlimited attempts against the
+== password by simply calling ChangePasswordUser2
+== repeatedly.
+==
+== This is available without any other authentication.
+==
+===========================================================
+
+===========
+Description
+===========
+
+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.
+
+As this was found during an internal audit of the Samba code there are
+no currently known exploits for this problem (as of March 11th 2014).
+
+=======
+Caveats
+=======
+
+Most sites do not configure the bad password lockout feature. Typically
+it is only enabled when Samba is configured as a Domain Controller, so
+most file server deployments are not impacted.
+
+Additionally, for this feature to be effective Samba must be the sole
+source of authentication on the network. (Otherwise synchronised
+services such as an LDAP backend or the UNIX /etc/shadow file could be
+the weak point instead).
+
+This patch does not implement bad password lockout for the Active
+Directory Domain Controller. The bad password lockout feature is not
+implemented at all in that configuration. The Samba Team plans to
+address this deficiency as feature in a future release of the AD DC.
+
+The patch to remove the samr_ChangePasswordUser call is not strictly
+required, as this call is only available to administrators already able
+to reset passwords. We include it to avoid a future well-meaning patch
+that might restore it as a valid password-change mechanism. If used, it
+would also bypass restrictions on password complexity, history and any
+restriction defined via the 'unix passwd sync', 'pam password change'
+and 'ldap password sync' smb.conf options.
+
+==================
+Patch Availability
+==================
+
+Patches addressing all these issues have been posted to:
+
+ http://www.samba.org/samba/security/
+
+Samba versions 3.6.23, 4.0.16, and 4.1.6 have been released to
+address this issue. Patches for 3.4.17 and 3.5.22 have not been
+provided as these are now beyond our security support window.
+
+==========
+Workaround
+==========
+
+None.
+
+=======
+Credits

+This problem was found by an internal audit of the Samba code by
+Andrew Bartlett of Catalyst IT. Special thanks also go to Univention GmbH.

+===========================================================
+
+===========
+Description
+===========
+
+Samba versions 4.0.0 and above have a flaw in the smbcacls command. If

+==========

+==========
+
