CVE-2018-14624 – 389-ds-base: Server crash through modify command with large DN
https://notcve.org/view.php?id=CVE-2018-14624
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.

CVE-2018-10850 – 389-ds-base: race condition on reference counter leads to DoS using persistent search
https://notcve.org/view.php?id=CVE-2018-10850
389-ds-base before versions 1.4.0.10, 1.3.8.3 is vulnerable to a race condition in the way 389-ds-base handles persistent search, resulting in a crash if the server is under load. An anonymous attacker could use this flaw to trigger a denial of service. 389-ds-base en versiones anteriores a la 1.4.0.10 y 1.3.8.3 es vulnerable a una condición de carrera por la forma en la que 389-ds-base gestiona las búsquedas persistentes.

CVE-2018-1089 – 389-ds-base: ns-slapd crash via large filter value in ldapsearch
https://notcve.org/view.php?id=CVE-2018-1089
389-ds-base before versions 1.4.0.9, 1.3.8.1, 1.3.6.15 did not properly handle long search filters with characters needing escapes, possibly leading to buffer overflows. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service. 389-ds-base en versiones anteriores a la 1.4.0.9, 1.3.8.1 y 1.3.6.15 no gestionó correctamente los filtros de búsqueda largos con caracteres que necesitan escapado. Esto podría conducir a desbordamientos de búfer. Un atacante remoto no autenticado podría emplear este error para hacer que ns-slapd se cierre inesperadamente mediante una petición LDAP especialmente manipulada que resulta en una denegación de servicio (DoS). It was found that 389-ds-base did not properly handle long search filters with characters needing escapes, possibly leading to buffer overflows. • http://www.securityfocus.com/bid/104137 https://access.redhat.com/errata/RHSA-2018:1364 https://access.redhat.com/errata/RHSA-2018:1380 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-1089 https://lists.debian.org/debian-lts-announce/2018/07/msg00018.html https://access.redhat.com/security/cve/CVE-2018-1089 https://bugzilla.redhat.com/show_bug.cgi?id=1559802 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
