Descriptions
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).
