CVE-2015-5252 – samba: Insufficient symlink verification in smbd
https://notcve.org/view.php?id=CVE-2015-5252
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 •
CVE-2015-5299 – Samba: Missing access control check in shadow copy code
https://notcve.org/view.php?id=CVE-2015-5299
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. La función shadow_copy2_get_shadow_copy_data en modules/vfs_shadow_copy2.c 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 no verifica que el privilegio de acceso al DIRECTORY_LIST ha sido concedido, lo que permite a atacantes remotos acceder a instantáneas visitando un directorio shadow copy. A missing access control flaw was found in Samba. A remote, authenticated attacker could use this flaw to view the current snapshot on a Samba share, despite not having DIRECTORY_LIST access rights. • 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-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-862: Missing Authorization •
CVE-2013-4408 – samba: Heap-based buffer overflow due to incorrect DCE-RPC fragment length field check

CVE-2013-0454
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 •
