While not exploitable from outside I can crash my CISCO 1005 running IOS 10.3(8) by setting the MTU to 15kb. A couple of seconds later the box will freeze. Just to show how tested the thing is ... IOS is probably not as badly affected as other operating systems because few people outside of CISCO have the required knowledge about the OS internals, so writing a useable exploit is hard. Ralf |
