Improper handling of Router Advertisements in NetworkManager could cause a Denial of Service condition in IPv6 network stacks.
|Package||net-misc/networkmanager on all architectures|
|Affected versions||< 1.0.2|
|Unaffected versions||>= 1.0.2|
NetworkManager is an universal network configuration daemon for laptops, desktops, servers and virtualization hosts.
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.
A remote attacker on the same network segment could cause a Denial of Service condition in NetworkManager
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"
