NVD Description

Note: Versions mentioned in the description apply only to the upstream openvswitch package and not the openvswitch package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses.
