Descriptions
The Netlink implementation in the Linux kernel before 3.2.30 does not properly handle messages that lack SCM_CREDENTIALS data, which might allow local users to spoof Netlink communication via a crafted message, as demonstrated by a message to (1) Avahi or (2) NetworkManager.
La implementación Netlink en el kernel Linux antes de v3.2.30, no controla correctamente los mensajes que carecen de datos SCM_CREDENTIALS, lo que podría permitir a usuarios locales falsificar la comunicación Netlink a través de un mensaje elaborado, como lo demuestra un mensaje para (1) Avahi o (2) NetworkManager.
