Ubuntu 16.04 LTS / 18.04 LTS / 18.10 : systemd vulnerability (USN-3806-1)
High Nessus Plugin ID 118750
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionFelix 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.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected systemd package.
