Ubuntu 15.10 / 16.04 LTS : libndp vulnerability (USN-2980-1)

Medium Nessus Plugin ID 91218


The remote Ubuntu host is missing a security-related patch.


Julien Bernard discovered that libndp incorrectly performed origin checks when receiving Neighbor Discovery Protocol (NDP) messages. A remote attacker outside of the local network could use this issue to advertise a node as a router, causing a denial of service, or possibly to act as a man in the middle.

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.


Update the affected libndp0 package.
