27 Feb 2019 — A flaw was found in the way an LDAP search expression could crash the shared LDAP server process of a samba AD DC in samba before version 4.10. An authenticated user, having read permissions on the LDAP server, could use this flaw to cause denial of service. Se ha detectado un fallo en la manera en la que una expresión de búsqueda LDAP podría provocar el cierre inesperado del proceso del servidor LDAP de un AD DC de samba en samba en versiones anteriores a la 4.10.

27 Nov 2018 — A denial of service vulnerability was discovered in Samba's LDAP server before versions 4.7.12, 4.8.7, and 4.9.3. A CNAME loop could lead to infinite recursion in the server. An unprivileged local attacker could create such an entry, leading to denial of service. Se ha descubierto una vulnerabilidad de denegación de servicio (DoS) en el servidor LDAP de Samba en versiones anteriores a la 4.7.12, 4.8.7, y 4.9.3. Un bucle CNAME podría conducir a una recursión infinita en el servidor. • http://www.securityfocus.com/bid/106022 • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

27 Nov 2018 — Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the ... • http://www.securityfocus.com/bid/106023 • CWE-415: Double Free CWE-416: Use After Free •

27 Nov 2018 — Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service. Samba, desd... • http://www.securityfocus.com/bid/106027 • CWE-476: NULL Pointer Dereference •

14 Aug 2018 — The Samba Active Directory LDAP server was vulnerable to an information disclosure flaw because of missing access control checks. An authenticated attacker could use this flaw to extract confidential attribute values using LDAP search expressions. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.

13 Mar 2018 — All versions of Samba from 4.0.0 onwards are vulnerable to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon. Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash. Todas las versiones de Samba, desde la 4.0.0 en adelante, son vulnerables a un ataque de denegación de servicio (DoS) cuando el servicio RPC spoolss se configura para ejecutarse como demonio externo.

21 Nov 2017 — Samba before 4.7.3 might allow remote attackers to obtain sensitive information by leveraging failure of the server to clear allocated heap memory. Las versiones anteriores a la 4.7.3 de Samba podrían permitir que atacantes remotos obtengan información sensible aprovechando el error del servidor para borrar la memoria dinámica (heap) asignada.
