Ubuntu Security Notice USN-2980-1
May 17, 2016

libndp vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS
- Ubuntu 15.10


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

Software Description:
- libndp: Library for Neighbor Discovery Protocol


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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
  libndp0                         1.4-2ubuntu0.16.04.1

Ubuntu 15.10:
  libndp0                         1.4-2ubuntu0.15.10.1

After a standard system update you need to reboot your computer to make
all the necessary changes.
