Descripción |
|
|
Se ha descubierto una vulnerabilidad en libpam-ldap. La vulnerabilidad se debe a la forma de validar el acceso de los usuarios. La explotación de esta vulnerabilidad, mediante el intento de autenticar contra un servidor LDAP que no contiene un campo de datos opcional, podría permitir a un atacante remoto saltar el mecanismo de autenticación del servidor LDAP. |
