The remote CentOS host is missing one or more security updates.

Description

An update for NetworkManager, NetworkManager-libreswan, libnl3, and network-manager-applet is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

NetworkManager is a system network service that manages network devices and connections, attempting to keep active network connectivity when available. Its capabilities include managing Ethernet, wireless, mobile broadband (WWAN), and PPPoE devices, as well as providing VPN integration with a variety of different VPN services.

The libnl3 packages contain a convenience library that simplifies using the Linux kernel's Netlink sockets interface for network manipulation.

The following packages have been upgraded to a later upstream version:
NetworkManager (1.8.0), network-manager-applet (1.8.0). (BZ#1413312, BZ# 1414103, BZ#1441621)

Security Fix(es) in the libnl3 component :

* An integer overflow leading to a heap-buffer overflow was found in the libnl library. An attacker could use this flaw to cause an application compiled with libnl to crash or possibly execute arbitrary code in the context of the user running such an application.
(CVE-2017-0553)
