Problem Description:

+

With a 'scrub fragment reassemble' rule, a packet containing multiple IPv6 + fragment headers would be reassembled, and then immediately processed. That + is, a packet with multiple fragment extension headers would not be recognized + as the correct ultimate payload. Instead a packet with multiple IPv6 fragment + headers would unexpectedly be interpreted as a fragmented packet, rather than + as whatever the real payload is.

+

Impact:

+

IPv6 fragments may bypass firewall rules written on the assumption all + fragments have been reassembled and, as a result, be forwarded or processed + by the host.
