    You comment that this affects the “Cisco catalyst 6500 and Cisco router 7600 series” is incorrect. It affects the FWSM which resides in the “Cisco catalyst 6500 and Cisco router 7600 series routers”. If you don't have the FWSM, then you are not affected. If you do have the FWSM, then only traffic passing through the FWSM is affected, not the entire “Cisco catalyst 6500 and Cisco router 7600 series”

    Yes, you are right your correction is much appreciated, the vulnerability is in the FWSM not in the Catalyst 6500 series switches and the 7600 series routers. I already fixed it, Many Thanks :-)
