Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 824545.
In Mitre's CVE dictionary: CVE-2016-3698.
More information:

Julien Bernard discovered that libndp, a library for the IPv6 Neighbor Discovery Protocol, does not properly perform input and origin checks during the reception of a NDP message. An attacker in a non-local network could use this flaw to advertise a node as a router, and cause a denial of service attack, or act as a man-in-the-middle.

For the stable distribution (jessie), this problem has been fixed in version 1.4-2+deb8u1.

We recommend that you upgrade your libndp packages.
