How does a UDP flood attack work?

A UDP flood works primarily by exploiting the steps that a server takes when it responds to a UDP packet sent to one of it’s ports. If no programs are receiving packets at that port, the server responds with a ICMP (ping) packet to inform the sender that the destination was unreachable.

How is the UDP flood different from the Ping of death?

The UDP flood is thus different from the ping of death which crashes the target system by exploiting a memory error and from the SYN flood which ties up resources on the server. One thing all the previously mentioned DoS attacks have in common is that they are intended to overwhelm the target and thus deny it being legitimately used.
