CVSS: 7.5EPSS: 1%CPEs: 8EXPL: 0CVE-2017-15134 – 389-ds-base: Remote DoS via search filters in slapi_filter_sprintf in slapd/util.c
https://notcve.org/view.php?id=CVE-2017-15134
A stack buffer overflow flaw was found in the way 389-ds-base 1.3.6.x before 1.3.6.13, 1.3.7.x before 1.3.7.9, 1.4.x before 1.4.0.5 handled certain LDAP search filters. 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 desbordamiento de búfer basado en pila en la forma en la que 389-ds-base, en versiones 1.3.6.x anteriores a la 1.3.6.13, versiones 1.3.7.x anteriores a la 1.3.7.9 y versiones 1.4.x anteriores a la 1.4.0.5, gestionaba ciertos filtros de búsqueda LDAP. 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). A stack buffer overflow flaw was found in the way 389-ds-base handled certain LDAP search filters. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00033.html http://www.securityfocus.com/bid/102790 https://access.redhat.com/errata/RHSA-2018:0163 https://bugzilla.redhat.com/show_bug.cgi?id=1531573 https://lists.debian.org/debian-lts-announce/2018/07/msg00018.html https://pagure.io/389-ds-base/c/6aa2acdc3cad9 https://access.redhat.com/security/cve/CVE-2017-15134 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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. Un atacante remoto no autenticado podría emplear este error para omitir el proceso de autenticación bajo circunstancias muy excepcionales.
