Resumen:	The remote host is missing an update for the 'libndp'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'libndp' package(s) announced via the referenced advisory. Vulnerability Insight: 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) Red Hat would like to thank Julien Bernard (Viagnie) for reporting this issue. Affected Software/OS: libndp on Red Hat Enterprise Linux Server (v. 7) Solution: Please Install the Updated Packages. CVSS Score: 6.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:P/A:P
