CVSS: 7.4EPSS: 0%CPEs: 12EXPL: 0CVE-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). A flaw was found in the way samba client used encryption with the max protocol set as SMB3. • http://www.securityfocus.com/bid/100917 http://www.securitytracker.com/id/1039401 https://access.redhat.com/errata/RHSA-2017:2790 https://access.redhat.com/errata/RHSA-2017:2858 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-12151 https://security.netapp.com/advisory/ntap-20170921-0001 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03817en_us https://www.debian.org/security/2017/dsa-3983 https://www.samba.org/samba/security/CVE-20 • CWE-300: Channel Accessible by Non-Endpoint CWE-310: Cryptographic Issues •
CVSS: 7.1EPSS: 53%CPEs: 14EXPL: 0CVE-2017-12163 – Samba: Server memory information leak over SMB1
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.

smbd in Samba before 4.4.10 and 4.5.x before 4.5.6 has a denial of service vulnerability (fd_open_atomic infinite loop with high CPU usage and memory consumption) due to wrongly handling dangling symlinks. smbd en Samba versiones anteriores a 4.4.10 y 4.5.x versiones anteriores a 4.5.6, tienen una vulnerabilidad de denegación de servicio (fd_open_atomic infinite loop con un alto uso de CPU y consumo de memoria) debido a un manejo inadecuado de los enlaces simbólicos colgantes. A flaw was found in the way Samba handled dangling symlinks. An authenticated malicious Samba client could use this flaw to cause the smbd daemon to enter an infinite loop and use an excessive amount of CPU and memory. • http://www.securityfocus.com/bid/99455 https://access.redhat.com/errata/RHSA-2017:1950 https://access.redhat.com/errata/RHSA-2017:2338 https://access.redhat.com/errata/RHSA-2017:2778 https://bugs.debian.org/864291 https://bugzilla.samba.org/show_bug.cgi?id=12572 https://git.samba.org/?p=samba.git%3Ba=commit%3Bh=10c3e3923022485c720f322ca4f0aca5d7501310 https://lists.debian.org/debian-lts-announce/2019/04/msg00013.html https://access.redhat.com/security/cve/CVE-2017-9461 https: • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

Samba before versions 4.6.1, 4.5.7 and 4.4.11 are vulnerable to a malicious client using a symlink race to allow access to areas of the server file system not exported under the share definition. Samba, en versiones anteriores a 4.6.1, 4.5.7 y 4.4.11, es vulnerable a un cliente malicioso que emplee una carrera symlink para permitir el acceso a áreas del sistema de archivos del servidor que no se exportan bajo la definición compartida. A race condition was found in samba server. A malicious samba client could use this flaw to access files and directories in areas of the server file system not exported under the share definitions. Samba suffers from a symlink race that permits opening files outside of the share directory. • https://www.exploit-db.com/exploits/41740 http://www.securityfocus.com/bid/97033 http://www.securitytracker.com/id/1038117 https://access.redhat.com/errata/RHSA-2017:1265 https://access.redhat.com/errata/RHSA-2017:2338 https://access.redhat.com/errata/RHSA-2017:2778 https://access.redhat.com/errata/RHSA-2017:2789 https://bugzilla.redhat.com/show_bug.cgi?id=1429472 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbns03755en_us https:/& • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2013-0454
The SMB2 implementation in Samba 3.6.x before 3.6.6, as used on the IBM Storwize V7000 Unified 1.3 before 1.3.2.3 and 1.4 before 1.4.0.1 and possibly other products, does not properly enforce CIFS share attributes, which allows remote authenticated users to (1) write to a read-only share; (2) trigger data-integrity problems related to the oplock, locking, coherency, or leases attribute; or (3) have an unspecified impact by leveraging incorrect handling of the browseable or "hide unreadable" parameter. Samba anterior a v3.6.6, tal como se utiliza en el IBM Storwize V7000 Unified v1.3 anterior a v1.3.2.3, y v1.4 anterior a v1.4.0.1 y posiblemente otros productos, no se aplican correctamente los atributos de CIFS de compartición, lo que permite a usuarios remotos autenticados para (1) escribir en un participación de sólo lectura, (2) disparar problemas de integridad de datos relacionados con la operación de bloqueo, bloqueo, coherencia, arrendamiento de atributo, o (3) tener un impacto no especificado mediante el aprovechamiento de la manipulación incorrecta del parámetro "hide unreadable". • http://www.ibm.com/support/docview.wss?uid=ssg1S1004289 http://www.ubuntu.com/usn/USN-1802-1 https://bugzilla.redhat.com/show_bug.cgi?id=928419 https://bugzilla.samba.org/show_bug.cgi?id=8738 https://exchange.xforce.ibmcloud.com/vulnerabilities/80970 https://lists.samba.org/archive/samba-announce/2012/000259.html https://www.samba.org/samba/security/CVE-2013-0454 • CWE-264: Permissions, Privileges, and Access Controls •
