Ubuntu 17.04 / 17.10 : systemd vulnerability (USN-3466-1)
Medium Nessus Plugin ID 104213
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionKarim Hossen & Thomas Imbert discovered that systemd-resolved incorrectly handled certain DNS responses. A remote attacker could possibly use this issue to cause systemd to temporarily stop responding, resulting in a denial of service.
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.
