Summary
systemd vulnerability
Details
Felix Wilhelm discovered that the systemd-networkd DHCPv6 client incorrectly handled certain DHCPv6 messages. In configurations where systemd-networkd is being used, an attacker on the same network could use this issue to cause systemd-networkd to crash, resulting in a denial of service, or possibly execute arbitrary code.
