remote attacker to register arbitrary services. This could allow the
attacker to use spoofed UDP traffic to conduct a denial-of-service attack
with a significant amplification factor.

## Notes

### [sbeattie](https://launchpad.net/~sbeattie)

The SLP protocol was never meant to be made available to the
public Internet, as the RFC 2165 authors recognize: "Service Location
provides a dynamic configuration mechanism for applications in
local area networks. It is not a global resolution system for the
entire Internet; rather it is intended to serve enterprise networks
with shared services."
