+===========================================================
+== Subject: CVE-2014-8143: Elevation of privilege to Active Directory Domain Controller
+==
+== CVE ID#: CVE-2014-8143
+==
+== Versions: All versions of Samba's Active Directory Domain Controller
+== (including 4.0.0 and all pre-releases)
+==
+== Summary: In Samba's AD DC we neglected to ensure that
+== attempted modifications of the userAccountControl attribute
+== did not allow the UF_SERVER_TRUST_ACCOUNT bit to be set.
+==
+== This is applicable only if the attribute is otherwise permitted
+== to be modified.
+==
+===========================================================
+
+===========
+Description
+===========
+
+Samba's AD DC allows the administrator to delegate
+creation of user or computer accounts to specific users or groups.
+
+However, all released versions of Samba's AD DC did not implement the
+additional required check on the UF_SERVER_TRUST_ACCOUNT bit in the
+userAccountControl attributes.
+
+As this was found during an internal audit of the Samba code there are
+no currently known exploits for this problem (as of January 15th 2015).
+
+=======
+Caveats
+=======
+
+Most Samba deployments are not of the AD Domain Controller, but are of
+the classic domain controller, the file server or print server. Only
+the AD DC is affected by this issue.
+
+Additionally, most sites running the AD Domain Controller do not
+configure delegation for the creation of user or computer accounts,
+and so are not vulnerable to this issue, as no writes are permitted to
+the userAccountControl attribute, no matter what the value.
+
+==================
+Patch Availability
+==================
+
+Patches addressing all these issues have been posted to:
+
+ http://www.samba.org/samba/security/
+
+Samba versions 4.0.24, 4.1.16, and 4.2rc4 have been released to
+address this issue. Patches for 3.x are not required, as these
+do not contain the AD Domain Controller code.
+
+==========
+Workaround
+==========
+
+Do not delegate permission to create users or computers beyond the
+default of Domain Administrators.
+
+=======
+Credits
+=======
+
+This problem was found by an internal audit of the Samba code by
+Andrew Bartlett of Catalyst IT. Special thanks also go to Zentyal.
+
+Patches provided by Andrew Bartlett, Garming Sam of Catalyst IT and
+the Samba team.
