https://notcve.org/view.php?id=CVE-2015-5370
Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 does not properly implement the DCE-RPC layer, which allows remote attackers to perform protocol-downgrade attacks, cause a denial of service (application crash or CPU consumption), or possibly execute arbitrary code on a client system via unspecified vectors. Samba 3.x y 4.x en versiones anteriores a 4.2.11, 4.3.x en versiones anteriores a 4.3.8 y 4.4.x en versiones anteriores a 4.4.2 no implementa correctamente la capa DCE-RPC, lo que permite a atacantes remotos llevar a cabo protocol-downgrade attacks, provocar una denegación de servicio (caída de aplicación o consumo de CPU), o posiblemente ejecutar código arbitrario en un sistema cliente a través de vectores no especificados. Multiple flaws were found in Samba's DCE/RPC protocol implementation. A remote, authenticated attacker could use these flaws to cause a denial of service against the Samba server (high CPU load or a crash) or, possibly, execute arbitrary code with the permissions of the user running Samba (root). This flaw could also be used to downgrade a secure DCE/RPC connection by a man-in-the-middle attacker taking control of an Active Directory (AD) object and compromising the security of a Samba Active Directory Domain Controller (DC). • http://badlock.org http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182185.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182272.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182288.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00022.html http://lists.opensuse.or •

https://notcve.org/view.php?id=CVE-2015-7560
The SMB1 implementation in smbd in Samba 3.x and 4.x before 4.1.23, 4.2.x before 4.2.9, 4.3.x before 4.3.6, and 4.4.x before 4.4.0rc4 allows remote authenticated users to modify arbitrary ACLs by using a UNIX SMB1 call to create a symlink, and then using a non-UNIX SMB1 call to write to the ACL content. La implementación de SMB1 en smbd en Samba 3.x y 4.x en versiones anteriores a 4.1.23, 4.2.x en versiones anteriores a 4.2.9, 4.3.x en versiones anteriores a 4.3.6 y 4.4.x en versiones anteriores a 4.4.0rc4 permite a usuarios remotos autenticados modificar ACLs arbitrarias utilizando una llamada UNIX SMB1 para crear un enlace simbólico, y después usar una llamada no-UNIX SMB1 para escribir en el contenido de la ACL. A flaw was found in the way Samba handled ACLs on symbolic links. An authenticated user could use this flaw to gain access to an arbitrary file or directory by overwriting its ACL. • http://lists.fedoraproject.org/pipermail/package-announce/2016-March/178730.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/178764.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/180000.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00063.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00065.html http://lists.opensuse.org/opensuse-security-announce • CWE-284: Improper Access Control •

vfs.c in smbd in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3, when share names with certain substring relationships exist, allows remote attackers to bypass intended file-access restrictions via a symlink that points outside of a share. vfs.c en smbd en Samba 3.x y 4.x en versiones anteriores a 4.1.22, 4.2.x en versiones anteriores a 4.2.7 y 4.3.x en versiones anteriores a 4.3.3, cuando existen nombres de recursos compartidos con ciertas relaciones de subcadenas, permite a atacantes remotos eludir las restricciones de acceso a archivos destinadas a través de un enlace simbólico que apunta fuera de un recurso compartido. An access flaw was found in the way Samba verified symbolic links when creating new files on a Samba share. A remote attacker could exploit this flaw to gain access to files outside of Samba's share path. • http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174076.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174391.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00033.html http://lists.opensuse.org/opensuse-security-announce& • CWE-41: Improper Resolution of Path Equivalence CWE-264: Permissions, Privileges, and Access Controls •

https://notcve.org/view.php?id=CVE-2015-5296
Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 supports connections that are encrypted but unsigned, which allows man-in-the-middle attackers to conduct encrypted-to-unencrypted downgrade attacks by modifying the client-server data stream, related to clidfs.c, libsmb_server.c, and smbXcli_base.c. Samba 3.x y 4.x en versiones anteriores a 4.1.22, 4.2.x en versiones anteriores a 4.2.7 y 4.3.x en versiones anteriores a 4.3.3 admite conexiones que están cifradas pero no firmadas, lo que permite a atacantes man-in-the-middle llevar a cabo un ataque de degradación de cifrado-a-descifrado modificando el flujo de datos cliente-servidor, relacionado con clidfs.c, libsmb_server.c y smbXcli_base.c. A man-in-the-middle vulnerability was found in the way "connection signing" was implemented by Samba. A remote attacker could use this flaw to downgrade an existing Samba client connection and force the use of plain text. • http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174076.html http://lists.fedoraproject.org/pipermail/package-announce/2015-December/174391.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00033.html http://lists.opensuse.org/opensuse-security-announce& • CWE-20: Improper Input Validation CWE-345: Insufficient Verification of Data Authenticity •

The shadow_copy2_get_shadow_copy_data function in modules/vfs_shadow_copy2.c in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 does not verify that the DIRECTORY_LIST access right has been granted, which allows remote attackers to access snapshots by visiting a shadow copy directory.
