Cisco Security Advisory - 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. There is no workaround - Customers are urged to upgrade to unaffected versions of software as soon as possible.
