CVSS: 7.5EPSS: 9%CPEs: 67EXPL: 1CVE-2020-12243 – openldap: denial of service via nested boolean expressions in LDAP search filters
https://notcve.org/view.php?id=CVE-2020-12243
In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can result in denial of service (daemon crash). En el archivo filter.c en slapd en OpenLDAP versiones anteriores a 2.4.50, los filtros de búsqueda de LDAP con expresiones booleanas anidadas pueden resultar en una denegación de servicio (bloqueo del demonio). • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00016.html https://bugs.openldap.org/show_bug.cgi?id=9202 https://git.openldap.org/openldap/openldap/-/blob/OPENLDAP_REL_ENG_2_4/CHANGES https://git.openldap.org/openldap/openldap/-/commit/98464c11df8247d6a11b52e294ba5dd4f0380440 https://lists.debian.org/debian-lts-announce/2020/05/msg00001.html https://security.netapp.com/advisory/ntap-20200511-0003 https://support.apple.com/kb/HT211289 https://usn.ubuntu.com/4352-1 https&# • CWE-400: Uncontrolled Resource Consumption CWE-674: Uncontrolled Recursion •

An issue was discovered in the server in OpenLDAP before 2.4.48. When the server administrator delegates rootDN (database admin) privileges for certain databases but wants to maintain isolation (e.g., for multi-tenant deployments), slapd does not properly stop a rootDN from requesting authorization as an identity from another database during a SASL bind or with a proxyAuthz (RFC 4370) control. (It is not a common configuration to deploy a system where the server administrator and a DB administrator enjoy different levels of trust.) Se detectó un problema en el servidor en OpenLDAP anterior a versión 2.4.48. Cuando el administrador del servidor delega los privilegios de tipo rootDN (administrador de base de datos) para ciertas bases de datos, pero quiere mantener el aislamiento (por ejemplo, para implementaciones de múltiples inquilinos), slapd no detiene apropiadamente un rootDN de solicitar una autorización como una identidad de otra base de datos durante un enlace SASL o con un control proxyAuthz (RFC 4370). • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00058.html http://seclists.org/fulldisclosure/2019/Dec/26 https://kc.mcafee.com/corporate/index?page=content&id=SB10365 https://lists.debian.org/debian-lts-announce/2019/08/msg00024.html https://seclists.org/bugtraq/2019/Dec/23 https://security.netapp.com/advisory/ntap-20190822-0004 https://support.apple.com/kb/HT210788 https://usn.ubuntu.com/4 •

slapd in OpenLDAP 2.4.45 and earlier creates a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill `cat /pathname`" command, as demonstrated by openldap-initscript. slapd en OpenLDAP en su versión 2.4.45 y anteriores crea un archivo PID tras eliminar privilegios a una cuenta no-root, lo que podría permitir que usuarios locales terminen procesos arbitrarios aprovechando el acceso a esta cuenta no-root para modificar el archivo PID antes de que un script root ejecute un comando "kill `cat /pathname`". Esto se ha demostrado con openldap-initscript. • http://www.openldap.org/its/index.cgi?findid=8703 https://www.oracle.com/security-alerts/cpuapr2022.html • CWE-665: Improper Initialization •

https://notcve.org/view.php?id=CVE-2017-9287
servers/slapd/back-mdb/search.c in OpenLDAP through 2.4.44 is prone to a double free vulnerability. A user with access to search the directory can crash slapd by issuing a search including the Paged Results control with a page size of 0. servers/slapd/back-mdb/search.c en OpenLDAP hasta la versión 2.4.44 es propenso a una doble vulnerabilidad de liberación de memoria. Un usuario con acceso para buscar en el directorio puede hacer que slapd deje de funcionar al emitir una búsqueda que incluya el control Paged Results con un tamaño de página de 0. A double-free flaw was found in the way OpenLDAP's slapd server using the MDB backend handled LDAP searches. A remote attacker with access to search the directory could potentially use this flaw to crash slapd by issuing a specially crafted LDAP search query. • http://www.debian.org/security/2017/dsa-3868 http://www.openldap.org/its/?findid=8655 http://www.securityfocus.com/bid/98736 http://www.securitytracker.com/id/1038591 https://access.redhat.com/errata/RHSA-2017:1852 https://bugs.debian.org/863563 https://kc.mcafee.com/corporate/index?page=content&id=SB10365 https://www.oracle.com/security-alerts/cpuapr2022.html https://access.redhat.com/security/cve/CVE-2017-9287 https://bugzilla.redhat.com/show_bug.cgi?id=1456712 • CWE-415: Double Free CWE-416: Use After Free •
