CVSS: 5.3EPSS: 0%CPEs: 6EXPL: 0CVE-2020-35518 – 389-ds-base: information disclosure during the binding of a DN
https://notcve.org/view.php?id=CVE-2020-35518
When binding against a DN during authentication, the reply from 389-ds-base will be different whether the DN exists or not. This can be used by an unauthenticated attacker to check the existence of an entry in the LDAP database. Cuando se vincula con un DN durante la autenticación, la respuesta de 389-ds-base será diferente si el DN se presenta o no. Esto puede ser usado por un atacante no autenticado para comprobar la existencia de una entrada en la base de datos de LDAP. • https://bugzilla.redhat.com/show_bug.cgi?id=1905565 https://github.com/389ds/389-ds-base/commit/b6aae4d8e7c8a6ddd21646f94fef1bf7f22c3f32 https://github.com/389ds/389-ds-base/commit/cc0f69283abc082488824702dae485b8eae938bc https://github.com/389ds/389-ds-base/issues/4480 https://access.redhat.com/security/cve/CVE-2020-35518 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •

https://notcve.org/view.php?id=CVE-2019-3883
In 389-ds-base up to version 1.4.1.2, requests are handled by workers threads. Each sockets will be waited by the worker for at most 'ioblocktimeout' seconds. However this timeout applies only for un-encrypted requests. Connections using SSL/TLS are not taking this timeout into account during reads, and may hang longer.An unauthenticated attacker could repeatedly create hanging LDAP requests to hang all the workers, resulting in a Denial of Service. En 389-ds-base hasta la versión 1.4.1.2, las peticiones son manejadas por hilos de trabajo. • https://access.redhat.com/errata/RHSA-2019:1896 https://access.redhat.com/errata/RHSA-2019:3401 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3883 https://lists.debian.org/debian-lts-announce/2019/05/msg00008.html https://lists.debian.org/debian-lts-announce/2023/04/msg00026.html https://pagure.io/389-ds-base/issue/50329 https://pagure.io/389-ds-base/pull-request/50331 https://access.redhat.com/security/cve/CVE-2019-3883 https://bugzilla.redhat.com/show_bu • CWE-772: Missing Release of Resource after Effective Lifetime •

A flaw was found in 389 Directory Server. A specially crafted search query could lead to excessive CPU consumption in the do_search() function. An unauthenticated attacker could use this flaw to provoke a denial of service. Se ha descubierto un problema en 389 Directory Server.

A flaw was found in 389-ds-base before version 1.3.8.4-13. The process ns-slapd crashes in delete_passwdPolicy function when persistent search connections are terminated unexpectedly leading to remote denial of service.

A vulnerability was discovered in 389-ds-base through versions 1.3.7.10, 1.3.8.8 and 1.4.0.16. The lock controlling the error log was not correctly used when re-opening the log file in log__error_emergency(). An attacker could send a flood of modifications to a very large DN, which would cause slapd to crash.
