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') •

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 •

Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the KDC process. Samba, desde la versión 4.3.0 antes de las versiones 4.7.12, 4.8.7 y 4.9.3, es vulnerable a una denegación de servicio (DoS). Cuando se configura para aceptar la autenticación por smartcard, el KDC de Samba llamará a talloc_free() dos veces en la misma memoria si la entidad de seguridad en un certificado firmado de forma válida no coincide con la entidad en AS-REQ. • http://www.securityfocus.com/bid/106023 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16841 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-2018-16841.html • CWE-415: Double Free CWE-416: Use After Free •

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.

A denial of service vulnerability was discovered in Samba's LDAP server before versions 4.7.12, 4.8.7, and 4.9.3. A CNAME loop could lead to infinite recursion in the server. An unprivileged local attacker could create such an entry, leading to denial of service. Se ha descubierto una vulnerabilidad de denegación de servicio (DoS) en el servidor LDAP de Samba en versiones anteriores a la 4.7.12, 4.8.7, y 4.9.3. Un bucle CNAME podría conducir a una recursión infinita en el servidor. • http://www.securityfocus.com/bid/106022 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14629 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-2018-14629.html • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
