USN-2980-1: libndp vulnerability

Publication date

17 May 2016

Overview

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

Releases

Packages

  • libndp - Library for Neighbor Discovery Protocol

Details

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
machine-in-the-middle.
