Code Red (and it's siblings Code Red II, Code Red III) are worms that affect IIS 4/5 servers. They propogate by finding other 'vulnerable' servers. Further info is at:
A DoS (Denial of Service) is when an attacker floods a service or overwhelms a service with packets. DoSes come both in local forms, as a resource starvation effect (e.g., using up CPU cycles to 100%, using all RAM, using all disk space) and/or a remote form (e.g., ping of death is too many pings being sent for an OS to handle). Often these attacks result in a server/service not being available until the attack subsides.

It depends on the DoS type. There are really 3 DoS types: simple DoS, DDoS (Distributed DoS), and DRDoS (Distributive Reflective DoS).
Some DoSes use malformed ICMP packets. Others use malformed SYN packets. It depends on the attack.
Now, if you want to see the actual code, find the name of the DoS (e.g., Smurf, Jolt, etc.) and do a search on Google. There are quite a few excellent reports on what these attacks did and how they work. Some are used today (like in my classroom against my students.. ) but we haven't seen them as much as previously.

One of the best analysis IMO can be found on eeye's site.

click here the full stiry.
Code Red II, the self-propagating Internet worm, is slowly working its way around the United States, causing sporadic outages and running up an immense tab in its wake.
