USN-2980-1: libndp vulnerability
Ubuntu Security Notice USN-2980-1
17th May, 2016
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS

libndp could be tricked into accepting an NDP message from outside the local network.

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.
The problem can be corrected by updating your system to the following package version:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
