An out-of-bounds memory read flaw was found in the way 389-ds-base handled certain LDAP search filters, affecting all versions including 1.4.x. 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. Se ha encontrado un error de lectura de memoria fuera de límites en la forma en la que 389-ds-base gestionaba ciertos filtros de búsqueda LDAP, que afecta a todas las versiones 1.4.x. 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 since 1.3.6.1 up to and including 1.4.0.3 did not always handle internal hash comparison operations correctly during the authentication process. A remote, unauthenticated attacker could potentially use this flaw to bypass the authentication process under very rare and specific circumstances. Se ha descubierto que 389-ds-base, desde la versión 1.3.6.1 y hasta e incluyendo la versión 1.4.0.3, no manipulaba siempre las operaciones de comparación de hash internas de manera correcta durante el proceso de autenticación.

389 Directory Server before 1.3.3.10 allows attackers to bypass intended access restrictions and modify directory entries via a crafted ldapmodrdn call. 389 Directory Server en versiones anteriores a la 1.3.3.10 permite que los atacantes omitan las restricciones de acceso previstas y modifiquen las entradas del directorio mediante una llamada ldapmodrdn manipulada. A flaw was found in the way Red Hat Directory Server performed authorization of modrdn operations. An unauthenticated attacker able to issue an ldapmodrdn call to the directory server could use this flaw to perform unauthorized modifications of entries in the directory server. • http://lists.fedoraproject.org/pipermail/package-announce/2015-May/157069.html http://www.securityfocus.com/bid/74392 https://access.redhat.com/errata/RHSA-2015:0895 https://bugzilla.redhat.com/show_bug.cgi?id=1209573 https://lists.debian.org/debian-lts-announce/2018/07/msg00018.html https://access.redhat.com/security/cve/CVE-2015-1854 • CWE-284: Improper Access Control CWE-863: Incorrect Authorization •
