I just tested land.c on a cisco 753 router running version 4.0 of the os.
It DID freeze the router when I hit it on port 23.  The router wasn't able
to reach the internal lan or the wan and some lights on the front of the
router were frozen also.  I couldn't ping or telnet to the router, the
only way to restart it is a hard reboot.

If anyone knows if this also affects larger cisco routers (1000 series
through 7500) let me know or post it back here on bugtraq.  As you can
see, there is a great potential of damage using this bug seeing as many of
the internet backbones are made up of cisco routers.
