Descriptions
OpenLDAP 2.4.22 allows remote attackers to cause a denial of service (crash) via a modrdn call with a zero-length RDN destination string, which is not properly handled by the smr_normalize function and triggers a NULL pointer dereference in the IA5StringNormalize function in schema_init.c, as demonstrated using the Codenomicon LDAPv3 test suite.
OpenLDAP 2.4.22 permite a atacantes remotos provocar una denegación de servicio(caída) a través de una llamada modrdn con una cadena de destino RDN con longitud cero, que no es manejada adecuadamente por la función smr_normalize y que provoca una deferencia a puntero nulo en la función IA5StringNormalize en schema_init.c, como se ha demostrado usando la suite de pruebas Codenomicon LDAPv3.
Multiple vulnerabilities were found in OpenLDAP, allowing for Denial of Service or a man-in-the-middle attack. Versions less than 2.4.35 are affected.
