RIP (Routing Information Protocol). Routers use RIP in order to advertise routing information to each other and communicate optimal paths.
References: [RFC 1058] & [RFC 2453]
Cisco NX-OS is vulnerable to a denial of service, caused by an error in the Routing Information Protocol (RIP) service engine. By sending a specially-crafted RIPv4 or RIPv6 message to UDP port 520, a remote attacker could exploit this vulnerability to cause the RIP service engine to restart.

ISC DHCP server 4.2 before 4.2.0-P2, when configured to use failover partnerships, allows remote attackers to cause a denial of service (communications-interrupted state and DHCP client service loss) by connecting to a port that is only intended for a failover peer, as demonstrated by a Nagios check_tcp process check to TCP port 520.
