Descriptions

The virNetServerProgramDispatchCall function in libvirt before 0.10.2 allows remote attackers to cause a denial of service (NULL pointer dereference and segmentation fault) via an RPC call with (1) an event as the RPC number or (2) an RPC number whose value is in a "gap" in the RPC dispatch table.

La función virNetServerProgramDispatchCall en libvirt antes de v0.10.2 permite a atacantes remotos provocar una denegación de servicio (desreferencia puntero NULL y fallo de segmentación) a través de una llamada RPC con (1) un evento como el número RPC o (2) un número RPC cuyo valor es en un "hueco" en la tabla RPC.
