Issue Overview:
It was found that kadmind’s kpasswd service did not perform any validation on incoming network packets, causing it to reply to all requests. A remote attacker could use this flaw to send spoofed packets to a kpasswd service that appear to come from kadmind on a different server, causing the services to keep replying packets to each other, consuming network bandwidth and CPU. (CVE-2002-2443)
