Description Mark J. Cox (Product Security) 2005-12-02 08:53:37 EST
http://www.cs.ucsb.edu/~krishna/igmp_dos/

With IGMP version 1 and 2 it is possible to inject a unicast report to a client
which will make it ignore multicast reports sent later by the router.

The fix is to only accept the report if is was sent to a multicast or unicast
address.  Fix from David Stevens at IBM and will be made upstream shortly.
