https://notcve.org/view.php?id=CVE-2018-1139
A flaw was found in the way samba before 4.7.9 and 4.8.4 allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled. A man-in-the-middle attacker could use this flaw to read the credential and other details passed between the samba server and client. Se ha detectado un fallo en la manera en la que samba en versiones anteriores a la 4.7.9 y 4.8.4 permitía el uso de la autenticación NTLMv1 débil incluso cuando NTLMv1 estaba explícitamente deshabilitado. Un atacante Man-in-the-Middle (MitM) podría utilizar este fallo para leer la credencial y otros detalles pasados entre el servidor y cliente de samba. A flaw was found in the way samba allowed the use of weak NTLMv1 authentication even when NTLMv1 was explicitly disabled. • http://www.securityfocus.com/bid/105084 https://access.redhat.com/errata/RHSA-2018:2612 https://access.redhat.com/errata/RHSA-2018:2613 https://access.redhat.com/errata/RHSA-2018:3056 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1139 https://security.gentoo.org/glsa/202003-52 https://security.netapp.com/advisory/ntap-20180814-0001 https://usn.ubuntu.com/3738-1 https://www.samba.org/samba/security/CVE-2018-1139.html https://access.redhat.com/security/cve/CV • CWE-20: Improper Input Validation CWE-522: Insufficiently Protected Credentials •

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. El servidor Samba Active Directory LDAP era vulnerable a una divulgación de información debido a la ausencia de comprobaciones de control de acceso. Un atacante autenticado podría utilizar este fallo para extraer valores de atributo confidenciales utilizando expresiones de búsqueda LDAP. • http://www.securityfocus.com/bid/105081 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10919 https://security.gentoo.org/glsa/202003-52 https://security.netapp.com/advisory/ntap-20180814-0001 https://usn.ubuntu.com/3738-1 https://www.debian.org/security/2018/dsa-4271 https://www.samba.org/samba/security/CVE-2018-10919.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •

A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable. Se ha descubierto un desbordamiento de búfer en la manera en la que los clientes de samba procesaban nombres de archivo excesivamente largos en un listado de directorios. Un servidor samba malicioso podría utilizar este defecto para provocar la ejecución de código arbitrario en un cliente de samba. • http://www.securityfocus.com/bid/105085 http://www.securitytracker.com/id/1042002 https://access.redhat.com/errata/RHSA-2018:2612 https://access.redhat.com/errata/RHSA-2018:2613 https://access.redhat.com/errata/RHSA-2018:3056 https://access.redhat.com/errata/RHSA-2018:3470 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10858 https://kc.mcafee.com/corporate/index?page=content&id=SB10284 https://security.gentoo.org/glsa/202003-52 https://security.netapp.com/advisory • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2018-1050
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. La falta de comprobaciones de saneamiento de entradas en algunos de los parámetros de entrada en las llamadas RPC spoolss podrían provocar que el servicio print spooler se cierre inesperadamente. A null pointer dereference flaw was found in Samba RPC external printer service. • http://www.securityfocus.com/bid/103387 http://www.securitytracker.com/id/1040493 https://access.redhat.com/errata/RHSA-2018:1860 https://access.redhat.com/errata/RHSA-2018:1883 https://access.redhat.com/errata/RHSA-2018:2612 https://access.redhat.com/errata/RHSA-2018:2613 https://access.redhat.com/errata/RHSA-2018:3056 https://bugzilla.redhat.com/show_bug.cgi?id=1538771 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6. • CWE-476: NULL Pointer Dereference •

On a Samba 4 AD DC the LDAP server in all versions of Samba from 4.0.0 onwards incorrectly validates permissions to modify passwords over LDAP allowing authenticated users to change any other users' passwords, including administrative users and privileged service accounts (eg Domain Controllers). En Samba 4 AD DC, el servidor LDAP en todas las versiones de Samba, desde la 4.0.0 en adelante, valida incorrectamente los permisos para modificar contraseñas por LDAP. Esto permite que usuarios autenticados cambien las contraseñas de cualquier otro usuario, incluyendo usuarios administrativos y cuentas de servicio privilegiadas (por ejemplo, Domain Controllers). • http://www.securityfocus.com/bid/103382 http://www.securitytracker.com/id/1040494 https://bugzilla.redhat.com/show_bug.cgi?id=1553553 https://lists.debian.org/debian-lts-announce/2019/04/msg00013.html https://security.gentoo.org/glsa/201805-07 https://security.netapp.com/advisory/ntap-20180313-0001 https://usn.ubuntu.com/3595-1 https://www.debian.org/security/2018/dsa-4135 https://www.samba.org/samba/security/CVE-2018-1057.html https://www.synology.com/support/security& • CWE-863: Incorrect Authorization •
