Overview

The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, remote attacker to register arbitrary services

The Service Location Protocol (SLP, RFC 2608) allows an unauthenticated, 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.
