https://www.theregister.co.uk/2018/10/26/systemd_dhcpv6_rce/ > A security bug in Systemd can be exploited over the network to, at best, potentially crash a vulnerable Linux machine, or, at worst, execute malicious code as root on the box. > The flaw therefore puts Systemd-powered Linux computers at risk of complete remote hijacking: maliciously crafted DHCPv6 packets received by vulnerable systems can exploit the programming cockup to arbitrarily change parts of memory, leading to potential code execution. This code could install malware, spyware, and other nasties, if successful.
