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.
