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

Affected packages =================

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.

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