A null pointer dereference flaw was found in the way samba checked database outputs from the LDB database layer. An authenticated attacker could use this flaw to crash a samba server in an Active Directory Domain Controller configuration. Samba versions before 4.7.9 and 4.8.4 are vulnerable. Se ha detectado una vulnerabilidad de desreferencia de puntero NULL en la manera en la que samba comprobaba las salidas de la base de datos desde la capa de la base de datos LDB. Un atacante autenticado podría utilizar esta vulnerabilidad para provocar el cierre inesperado de un servidor samba en una configuración Active Directory Domain Controller. • http://www.securityfocus.com/bid/105083 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-10918 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-2018-10918.html • CWE-476: NULL Pointer Dereference •

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.

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 •
