It was discovered that there was a buffer overflow vulnerability in libndp, a library for implementing IPv6’s “Neighbor Discovery Protocol” (NDP) and is used by Network Manager and other networking tools.

A local, malicious user could have caused a buffer overflow in Network Manager by sending a malformed IPv6 router advertisement packet. This issue existed because libndp was not correctly validating route length information.



For Debian 8 jessie, these problems have been fixed in version 1.4-2+deb8u2.

For Debian 9 stretch, these problems have been fixed in version 1.6-1+deb9u1.

We recommend that you upgrade your libndp packages.
