CVE-2019-10218 – samba: smb client vulnerable to filenames containing path separators
https://notcve.org/view.php?id=CVE-2019-10218
A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user. Se encontró un fallo en el cliente de samba, todas las versiones de samba anteriores a samba 4.11.2, 4.10.10 y 4.9.15, donde un servidor malicioso puede suministrar un nombre de ruta al cliente con separadores. Esto podría permitir al cliente acceder a archivos y carpetas fuera de los nombres de ruta de la red SMB. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00015.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10218 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2023/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OKPYHDFI7HRELVXBE5J4MTGSI35AKFBI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UMIYCYXCPRTVCVZ3TP6ZGPJ6RZS3IX4G https: • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

A flaw was found in samba 4.0.0 before samba 4.9.15 and samba 4.10.x before 4.10.10. An attacker can crash AD DC LDAP server via dirsync resulting in denial of service. Privilege escalation is not possible with this issue. Se encontró un fallo en samba versión 4.0.0 anteriores a samba 4.9.15 y samba versiones 4.10.x anteriores a 4.10.10. Un atacante puede bloquear el servidor AD DC LDAP por medio de la sincronización de directorios resultando en la denegación de servicio. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00015.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14847 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2023/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OKPYHDFI7HRELVXBE5J4MTGSI35AKFBI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XQ3IUACPZJXSC4OM6P2V4IC4QMZQZWPD https: • CWE-476: NULL Pointer Dereference •
CVE-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') •
CVE-2019-3824
https://notcve.org/view.php?id=CVE-2019-3824
A flaw was found in the way an LDAP search expression could crash the shared LDAP server process of a samba AD DC in samba before version 4.10. An authenticated user, having read permissions on the LDAP server, could use this flaw to cause denial of service. Se ha detectado un fallo en la manera en la que una expresión de búsqueda LDAP podría provocar el cierre inesperado del proceso del servidor LDAP de un AD DC de samba en samba en versiones anteriores a la 4.10. Un usuario autenticado con permisos de lectura en el servidor LDAP podría aprovechar este fallo para provocar una denegación de servicio (DoS). • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00035.html http://www.securityfocus.com/bid/107347 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3824 https://bugzilla.samba.org/show_bug.cgi?id=13773 https://lists.debian.org/debian-lts-announce/2019/03/msg00000.html https://security.netapp.com/advisory/ntap-20190226-0001 https://usn.ubuntu.com/3895-1 https://www.debian.org/security/2019/dsa-4397 • CWE-125: Out-of-bounds Read •
CVE-2018-16851
https://notcve.org/view.php?id=CVE-2018-16851
Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service. Samba, desde la versión 4.0.0 antes de las versiones 4.7.12, 4.8.7 y 4.9.3, es vulnerable a una denegación de servicio (DoS). • http://www.securityfocus.com/bid/106027 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16851 https://lists.debian.org/debian-lts-announce/2018/12/msg00005.html https://security.gentoo.org/glsa/202003-52 https://security.netapp.com/advisory/ntap-20181127-0001 https://usn.ubuntu.com/3827-1 https://usn.ubuntu.com/3827-2 https://www.debian.org/security/2018/dsa-4345 https://www.samba.org/samba/security/CVE-2018-16851.html • CWE-476: NULL Pointer Dereference •
