CVE-2018-1050 – samba: NULL pointer dereference in printer server process
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 •
CVE-2018-1057
https://notcve.org/view.php?id=CVE-2018-1057
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 •
CVE-2017-15275 – samba: Server heap-memory disclosure
https://notcve.org/view.php?id=CVE-2017-15275
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. A memory disclosure flaw was found in samba. An attacker could retrieve parts of server memory, which could contain potentially sensitive data, by sending specially-crafted requests to the samba server. • http://www.securityfocus.com/bid/101908 http://www.securitytracker.com/id/1039855 http://www.ubuntu.com/usn/USN-3486-1 http://www.ubuntu.com/usn/USN-3486-2 https://access.redhat.com/errata/RHSA-2017:3260 https://access.redhat.com/errata/RHSA-2017:3261 https://access.redhat.com/errata/RHSA-2017:3278 https://lists.debian.org/debian-lts-announce/2017/11/msg00029.html https://security.gentoo.org/glsa/201805-07 https://support.hpe.com/hpsc/doc/public/display?docLoc • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-14746 – samba: Use-after-free in processing SMB1 requests
https://notcve.org/view.php?id=CVE-2017-14746
Use-after-free vulnerability in Samba 4.x before 4.7.3 allows remote attackers to execute arbitrary code via a crafted SMB1 request. Vulnerabilidad de uso de memoria previamente liberada en las versiones 4.x de Samba anteriores a la 4.7.3 permiten que atacantes remotos ejecuten código arbitrario mediante una petición SMB1. A use-after-free flaw was found in the way samba servers handled certain SMB1 requests.

CVE-2017-12151 – samba: SMB2 connections don't keep encryption across DFS redirects
https://notcve.org/view.php?id=CVE-2017-12151
A flaw was found in the way samba client before samba 4.4.16, samba 4.5.14 and samba 4.6.8 used encryption with the max protocol set as SMB3. The connection could lose the requirement for signing and encrypting to any DFS redirects, allowing an attacker to read or alter the contents of the connection via a man-in-the-middle attack. Se ha encontrado un fallo en la forma en la que el cliente samba en versiones anteriores a samba 4.4.16, samba 4.5.14 y samba 4.6.8 utilizaba cifrado con el protocolo max establecido en SMB3. La conexión podía perder el requisito de firmar y cifrar con cualquier redirección DFS, lo que permitía a un atacante leer o alterar el contenido de la conexión mediante un ataque Man-in-the-Middle (MitM).
