16 Release Notes for Samba 4.0.1
18 =============================
21 This is a security release in order to address CVE-2013-0172.
24 Samba 4.0.0 as an AD DC may provide authenticated users with write access
25 to LDAP directory objects.
27 In AD, Access Control Entries can be assigned based on the objectClass
28 of the object. If a user or a group the user is a member of has any
29 access based on the objectClass, then that user has write access to that
32 Additionally, if a user has write access to any attribute on the object,
33 they may have access to write to all attributes.
35 An important mitigation is that anonymous access is totally disabled by
36 default. The second important mitigation is that normal users are
37 typically only given the problematic per-objectClass right via the
38 "pre-windows 2000 compatible access" group, and Samba 4.0.0 incorrectly
39 does not make "authenticated users" part of this group.
