Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

NetworkManager could be made to crash or run programs if it received specially crafted network traffic.

Software Description: - network-manager: Network connection manager

Details:

Felix Wilhelm discovered that the NetworkManager internal DHCPv6 client incorrectly handled certain DHCPv6 messages. In non-default configurations where the internal DHCP client is enabled, an attacker on the same network could use this issue to cause NetworkManager 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:
network-manager 1.12.4-1ubuntu1.1

Ubuntu 18.04 LTS:
network-manager 1.10.6-2ubuntu1.1

Ubuntu 16.04 LTS:
network-manager 1.2.6-0ubuntu0.16.04.3

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