Ubuntu Security Notice USN-3806-1

systemd vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- - Ubuntu 18.10
- - Ubuntu 18.04 LTS
- - Ubuntu 16.04 LTS
Summary:
systemd-networkd could be made to crash or run programs if it received
specially crafted network traffic.
Software Description:
- - systemd: system and service manager
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.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.10:
systemd 239-7ubuntu10.1
Ubuntu 18.04 LTS:
systemd 237-3ubuntu10.4

After a standard system update you need to reboot your computer to make
all the necessary changes.
