Detail

Synopsis

Improper handling of Router Advertisements in NetworkManager could cause a Denial of Service condition in IPv6 network stacks.

Background

NetworkManager is an universal network configuration daemon for laptops, desktops, servers and virtualization hosts.

Description

IPv6 Neighbour Discovery ICMP broadcast containing a non-route with a low hop limit causes a Denial of Service by lowering the hop limit on existing IPv6 routes in NetworkManager.

Impact

A remote attacker on the same network segment could cause a Denial of Service condition in NetworkManager

Workaround

There is no known workaround at this time.

Resolution

All NetworkManager users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/networkmanager-1.0.2"
