Package        : libndp
CVE ID         : CVE-2016-3698
Debian Bug     : 824545

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.
