Descriptions

389-ds-base before version 1.3.6 is vulnerable to an improperly NULL terminated array in the uniqueness_entry_to_config() function in the "attribute uniqueness" plugin of 389 Directory Server. An authenticated, or possibly unauthenticated, attacker could use this flaw to force an out-of-bound heap memory read, possibly triggering a crash of the LDAP service.

389-ds-base, en versiones anteriores a la 1.3.6, es vulnerable a un array terminado indebidamente en NULL en la función uniqueness_entry_to_config() en el plugin "attribute uniqueness" de 389 Directory Server. Un atacante autenticado o, posiblemente, sin autenticar, podría emplear este error para forzar una lectura fuera de límites de la memoria dinámica (heap), desencadenando un cierre inesperado del servicio LDAP.
