    {
      "lang": "en",
      "value": "A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak."

      "value": "Se encontr\u00f3 un desbordamiento de b\u00fafer en la regi\u00f3n stack de la memoria en el dispositivo virtio-net de QEMU. Este problema ocurre al vaciar TX en la funci\u00f3n virtio_net_flush_tx si las funciones de invitado VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 y VIRTIO_NET_F_MRG_RXBUF est\u00e1n habilitadas. Esto podr\u00eda permitir que un usuario malintencionado sobrescriba las variables locales asignadas en la pila. Espec\u00edficamente, la variable `out_sg` podr\u00eda usarse para leer una parte de la memoria del proceso y enviarla al cable, provocando una fuga de informaci\u00f3n."
