Ensure your Ubuntu system is up-to-date to address the libndp security vulnerability that poses risks for network exploitation and service interruptions.
libndp could be tricked into accepting an NDP message from outside the local network.

Summary

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

local network.

Software Description:

- 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 man

in the middle.
