A defect in Cisco IOS Software running on all models of Gigabit
Switch Routers (GSRs) configured with Gigabit Ethernet or Fast
Ethernet cards may cause packets to be forwarded without correctly
evaluating configured access control lists (ACLs). In addition to
circumventing the access control lists, it is possible to stop an
interface from forwarding any packets, thus causing a denial of
service.
This vulnerability is documented as Cisco bug ID CSCdp35794.
