Description:Summary:
The remote host is missing an update for the 'NetworkManager and libnl3'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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)
