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.
