HP Network Node Manager is "a network mapping and management application that allows administrators to monitor and control their networks. The ovtopmd process listens, in a default configuration, on TCP port 2532". Remote exploitation of a denial of service vulnerability in Hewlett-Packard's Network Node Manager product allows attackers to crash the ovtopmd process.
