systemd is vulnerable to denial of service. The vulnerability exists due to the on_stream_io() function and dns_stream_complete() function in resolved-dns-stream.c does not properly increment the reference counting for the DnsStream object, allowing an attacker to cause a system crash through the dereference in the DNSStream object, causing the user-after-free when the reference is still used later.
