CVSS: 5.9EPSS: 0%CPEs: 251EXPL: 0CVE-2016-2112 – samba: Missing downgrade detection
https://notcve.org/view.php?id=CVE-2016-2112
The bundled LDAP client library in 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 recognize the "client ldap sasl wrapping" setting, which allows man-in-the-middle attackers to perform LDAP protocol-downgrade attacks by modifying the client-server data stream. El paquete de la librería cliente LDAP en 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 reconoce el ajuste "client ldap sasl wrapping", lo que permite a atacantes man-in-the-middle llevar a cabo ataques de degradación de protocolo LDAP modificando el flujo de datos cliente-servidor. It was found that Samba's LDAP implementation did not enforce integrity protection for LDAP connections. A man-in-the-middle attacker could use this flaw to downgrade LDAP connections to use no integrity protection, allowing them to hijack such connections. • 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 • CWE-254: 7PK - Security Features CWE-300: Channel Accessible by Non-Endpoint •
CVSS: 5.9EPSS: 0%CPEs: 251EXPL: 0CVE-2016-2115 – samba: Smb signing not required by default when smb client connection is used for ipc usage
https://notcve.org/view.php?id=CVE-2016-2115
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 require SMB signing within a DCERPC session over ncacn_np, which allows man-in-the-middle attackers to spoof SMB clients by modifying the client-server data stream. 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 requiere firmado SMB dentro de una sesión DCERPC sobre ncacn_np, lo que permite a atacantes man-in-the-middle suplantar clientes SMB modificando el flujo de datos cliente-servidor It was found that Samba did not enable integrity protection for IPC traffic by default. A man-in-the-middle attacker could use this flaw to view and modify the data sent between a Samba server and a client. • 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 • CWE-254: 7PK - Security Features CWE-300: Channel Accessible by Non-Endpoint •

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 •
