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 •

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. An unauthenticated attacker could send specially-crafted SMB1 requests to cause the server to crash or execute arbitrary code. • http://www.securityfocus.com/bid/101907 http://www.securitytracker.com/id/1039856 http://www.ubuntu.com/usn/USN-3486-1 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://security.gentoo.org/glsa/201805-07 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03817en_us https://www.debian.org/security/2017/dsa-4043 https://www.samba.or • CWE-416: Use After Free •

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).

https://notcve.org/view.php?id=CVE-2017-12163
An information leak flaw was found in the way SMB1 protocol was implemented by Samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8. A malicious client could use this flaw to dump server memory contents to a file on the samba share or to a shared printer, though the exact area of server memory cannot be controlled by the attacker. Se ha descubierto una vulnerabilidad de fuga de información en la manera en la que Samba, en versiones anteriores a la 4.4.16, versiones 4.5.x anteriores a la 4.5.14 y versiones 4.6.x anteriores a la 4.6.8, implementó el protocolo SMB1. Un cliente malicioso podría utilizar esta vulnerabilidad para volcar los contenidos de la memoria del servidor en un archivo en el almacenamiento de samba o en una impresora compartida, aunque el atacante no pueda controlar el área exacta de memoria del servidor.
