    Ubuntu Security Notice USN-3806-1
    November 05, 2018
    
    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
    
    Ubuntu 16.04 LTS:
      systemd                         229-4ubuntu21.6
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
