Descriptions

The SMTP server in Postfix before 2.5.13, 2.6.x before 2.6.10, 2.7.x before 2.7.4, and 2.8.x before 2.8.3, when certain Cyrus SASL authentication methods are enabled, does not create a new server handle after client authentication fails, which allows remote attackers to cause a denial of service (heap memory corruption and daemon crash) or possibly execute arbitrary code via an invalid AUTH command with one method followed by an AUTH command with a different method.

El servidor SMTP en Postfix anterior a v2.5.13, v2.6.x anterior a v2.6.10, v2.7.x anterior a v2.7.4, y v2.8.x anterior a v2.8.3, cuando ciertos métodos Cyrus SASL de autenticación son activados, no crea un nuevo manejador de servidor después de que la autentificación falle, lo que permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria libre y caída de demonio) o posiblemente ejecutar código de su elección a tra´ves de un comando AUTH no válido con un método seguido por un comando AUTH con un método diferente.
