    Removed Translation Vulnerabilidad en libuser en versiones anteriores 0.56.13-8 y 0.60 anterior a 0.60.7, como se usa en el programa userhelper en el paquete usermode, directamente modifica /etc/passwd, lo que permite a usuarios locales provocar una denegación de servicio (estado de archivo inconsistente) al provocar un error durante la modificación. NOTA: este problema se puede combinar con CVE-2015-3245 para obtener privilegios.
