=============================
+ 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).
+
+o CVE-2013-4408:
+ 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).
+
+o CVE-2012-6150:
+ 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.
