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 •

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 •
