Ubuntu 16.04 LTS / 18.04 LTS : systemd vulnerability (USN-3806-1)

high Nessus Plugin ID 118750

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3806-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
