BUG | Question ? | Test | Cisco IOS Interface Blocked by IPv4 Packet

Discussion in 'Cisco' started by Markus Zielonka, Jul 17, 2003.

  1. Hello NG,

    is it possible to test this BUG?

    I search a method to test the IOS.

    A device receiving these specifically crafted IPv4 packets will force
    the inbound interface to stop processing traffic. The device may stop
    processing packets destined to the router, including routing protocol
    packets and ARP packets. No alarms will be triggered, nor will the
    router reload to correct itself. This issue can affect all Cisco
    devices running Cisco IOS software. This vulnerability may be
    exercised repeatedly resulting in loss of availability until a
    workaround has been applied or the device has been upgraded to a fixed
    version of code.

    what do you think would happen if Cisco released a nice little tool to test
    a bug? You could then 'test' someone else's network.

    Take their word for it, if your IOS is vulnerable, upgrade :)
