   I would appreciate any links or information relative to ATM Switch
vulnerabilities or risks, especially anything that works below the IP
level.  Thanks.

what kind of ATM? LANE? CLIP? pure ATM?

if its LANE, you can abuse the ARP table size and shove unicasts to the
BUS, leaking traffic, on some switches, especially edge devices. its not
pretty. Fore (now marconi) used to have some API code for doing ATM cells
from the ground up.

just some thoughts. also, a lot of Fore switches ran Solaris. you could
get in and abuse the switching tables there.
