Cisco Security Advisory: Cisco IOS Interface Blocked by IPv4 Packet http://www.cisco.com/warp/public/707/cisco-sa-20030717-blocked.shtml
IS anyone seeing this exploited in the wild? It'd be good to know if we need to do panic upgrade or can schedule it for our next maintenance window (which is during the weekend).
I've been keeping my ear close to the ground. A number of people have been attempting to find the packet to better place ACLs in the internet community, but i've also heard of people seeing more series of "unusual" packets on their network in the past few days as well. Nobody has found it yet that i'm aware of and Cisco found this in internal testing so I expect you will be safe for a period of time sufficent to do weekend upgrades. - jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
