Samba 4.10.x before 4.10.5 has a NULL pointer dereference, leading to an AD DC LDAP server Denial of Service. This is related to an attacker using the paged search control. The attacker must have directory read access in order to attempt an exploit. Samba versión 4.10.x anterior a 4.10.5, presenta una desreferencia de puntero NULL, lo que conlleva a una denegación de servicio del servidor LDAP DC basado en AD. Esto está relacionado con un atacante que utiliza el control de búsqueda paginado. • http://www.securityfocus.com/bid/108823 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZQ3LCJNJ3ONHIRKDSKOTT6QGXALLCHVG https://usn.ubuntu.com/4018-1 https://www.samba.org/samba/security/CVE-2019-12436.html https://www.synology.com/security/advisory/Synology_SA_19_27 • CWE-476: NULL Pointer Dereference •

A flaw was found in samba's Heimdal KDC implementation, versions 4.8.x up to, excluding 4.8.12, 4.9.x up to, excluding 4.9.8 and 4.10.x up to, excluding 4.10.3, when used in AD DC mode. A man in the middle attacker could use this flaw to intercept the request to the KDC and replace the user name (principal) in the request with any desired user name (principal) that exists in the KDC effectively obtaining a ticket for that principal. Se encontró un fallo en la implementación de Heimdal KDC de samba, versiones 4.8.x hasta 4.8.12 excluyéndola, versiones 4.9.x hasta 4.9.8 excluyéndola, y versiones 4.10.x hasta 4.10.3 excluyéndola, cuando es usado en modo AD DC . Un atacante de tipo man in the middle podría usar este fallo para interceptar la petición al KDC y reemplazar el nombre de usuario (principal) en la petición con cualquier nombre de usuario (principal) deseado que exista en el KDC obteniendo efectivamente un ticket para este principal. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00026.html http://seclists.org/fulldisclosure/2019/Aug/11 http://seclists.org/fulldisclosure/2019/Aug/13 http://seclists.org/fulldisclosure/2019/Aug/14 http://seclists.org/fulldisclosure/2019/Aug/15 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16860 https://seclists.org/bugtraq/2019/Aug/21 https://seclists.org/bugtraq/2019/Aug/22 https://seclists.org/bugtraq/2019/Aug/23 https://seclists.org/bugtr • CWE-358: Improperly Implemented Security Check for Standard •

https://notcve.org/view.php?id=CVE-2019-3870
A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8. Within this directory, files are created with mode 0666, which is world-writable, including a sample krb5.conf, and the list of DNS names and servicePrincipalName values to update. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3870 https://bugzilla.samba.org/show_bug.cgi?id=13834 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6354GALK73CZWQKFUG7AWB6EIEGFMF62 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JTJVFA3RZ6G2IZDTVKLHRMX6QBYA4GPA https://support.f5.com/csp/article/K20804356 https://www.samba.org/samba/security/CVE-2019-3870.html https://www.synology.com/security/advisory/Synology_SA_19 • CWE-276: Incorrect Default Permissions •
CVSS: 5.5EPSS: 0%CPEs: 10EXPL: 0CVE-2019-3880 – samba: save registry file outside share as unprivileged user
https://notcve.org/view.php?id=CVE-2019-3880
A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable. Se encontró un fallo en la forma en que samba implementó RPC endpoint, que emula la API de servicios de registro de Windows. Un atacante sin privilegios podría usar este defecto para crear un nuevo archivo de registro hive en cualquier lugar que tenga permisos Unix, lo que podría llevar a la creación de un nuevo archivo en el recurso compartido de Samba. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00106.html https://access.redhat.com/errata/RHSA-2019:1966 https://access.redhat.com/errata/RHSA-2019:1967 https://access.redhat.com/errata/RHSA-2019:2099 https://access.redhat.com/errata/RHSA-2019:3582 https://access.redhat.com/security/cve/cve-2019-3880 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3880 https://lists.debian.org/d • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
