17th May, 2016
libndp vulnerability
A security issue affects these releases of Ubuntu and its
derivatives:
- Ubuntu 16.04 LTS
- Ubuntu 15.10
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.
