    {

      "value": "A use-after-free vulnerability was found in systemd. This issue occurs due to the on_stream_io() function and dns_stream_complete() function in 'resolved-dns-stream.c' not incrementing the reference counting for the DnsStream object. Therefore, other functions and callbacks called can dereference the DNSStream object, causing the use-after-free when the reference is still used later."

    {
      "lang": "es",
      "value": "Se ha encontrado una vulnerabilidad de uso de memoria previamente liberada en systemd. Este problema ocurre debido a que las funciones on_stream_io() y dns_stream_complete() en \"resolved-dns-stream.c\" no incrementan el conteo de referencias para el objeto DnsStream. Por lo tanto, otras funciones y callbacks llamados pueden hacer referencia al objeto DNSStream, causando un uso de memoria previamente liberada cuando la referencia sigue us\u00e1ndose m\u00e1s tarde"
