Title:Mageia: Security Advisory (MGASA-2016-0185)
Summary:The remote host is missing an update for the 'libndp' package(s) announced via the MGASA-2016-0185 advisory.
Description:Summary:
The remote host is missing an update for the 'libndp' package(s) announced via the MGASA-2016-0185 advisory.

Vulnerability Insight:
Updated libndp package fixes security vulnerability:

Libndp is a library (used by NetworkManager) that provides a wrapper for the
IPv6 Neighbor Discovery Protocol. It also provides a tool named ndptool for
sending and receiving NDP messages.

Security Fix(es):

It was found that libndp did not properly validate and check the origin of
Neighbor Discovery Protocol (NDP) messages. An attacker on a non-local network
could use this flaw to advertise a node as a router, allowing them to perform
man-in-the-middle attacks on a connecting client, or disrupt the network
connectivity of that client. (CVE-2016-3698)

Affected Software/OS:
'libndp' package(s) on Mageia 5.

Solution:
Please install the updated package(s).
