USN-2980-1: libndp vulnerability
17 May 2016
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.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04
Ubuntu 15.10
After a standard system update you need to reboot your computer to make
all the necessary changes.
