28 Apr 2020 — A flaw was found when using samba as an Active Directory Domain Controller. Due to the way samba handles certain requests as an Active Directory Domain Controller LDAP server, an unauthorized user can cause a stack overflow leading to a denial of service. The highest threat from this vulnerability is to system availability. This issue affects all samba versions before 4.10.15, before 4.11.8 and before 4.12.2. Se encontró un fallo cuando se usa samba como un Active Directory Domain Controller. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00054.html • CWE-674: Uncontrolled Recursion •

21 Jan 2020 — All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate.

10 Dec 2019 — All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the (poorly named) dnsserver RPC pipe provides administrative facilities to modify DNS records and zones. Samba, when acting as an AD DC, stores DNS records in LDAP. In AD, the default permissions on the DNS partition allow creation of new records by authenticated users. This is used for example to allow machines to self-register in DNS. If a DNS record was created that case-insensitively matched the ... • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00038.html • CWE-276: Incorrect Default Permissions •

In AD this is implemented by a user attribute delegation_not_allowed (aka not-delegated), which translates to disallow-forwardable.

29 Oct 2019 — A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dict... • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00015.html • CWE-305: Authentication Bypass by Primary Weakness CWE-521: Weak Password Requirements •
