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 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14629 https://lists.debian.org/debian-lts-announce/2018/12/msg00005.html https://security.gentoo.org/glsa/202003-52 https://security.netapp.com/advisory/ntap-20181127-0001 https://usn.ubuntu.com/3827-1 https://usn.ubuntu.com/3827-2 https://www.debian.org/security/2018/dsa-4345 https://www.samba.org/samba/security/CVE-2018-14629.html • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

A missing input sanitization flaw was found in the implementation of LDP database used for the LDAP server. An attacker could use this flaw to cause a denial of service against a samba server, used as a Active Directory Domain Controller. All versions of Samba from 4.8.0 onwards are vulnerable Se ha detectado la ausencia de medidas de saneamiento de entradas en la implementación de la base de datos LDP utilizada para el servidor LDAP. Un atacante podría usar este fallo para causar una denegación de servicio (DoS) contra un servidor samba, usado como un controlador de dominio de directorio activo. Todas las versiones de Samba a partir de la 4.8.0 son vulnerables. • http://www.securityfocus.com/bid/105082 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1140 https://bugzilla.samba.org/show_bug.cgi?id=13374 https://security.gentoo.org/glsa/202003-52 https://security.netapp.com/advisory/ntap-20180814-0001 https://www.samba.org/samba/security/CVE-2018-1140.html • CWE-20: Improper Input Validation •

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 •
