Descriptions

The sosendto function in slirp/udp.c in QEMU before 2.1.2 allows local users to cause a denial of service (NULL pointer dereference) by sending a udp packet with a value of 0 in the source port and address, which triggers access of an uninitialized socket.

La función sosendto en slirp/udp.c en QEMU anterior a 2.1.2 permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo) mediante el envió de un paquete udp con un valor de 0 en el pueto y dirección de la fuente, lo que provoca el acceso a un socket no inicializado.

A NULL pointer dereference flaw was found in the way QEMU handled UDP packets with a source port and address of 0 when QEMU's user networking was in use. A local guest user could use this flaw to crash the guest.
