Kerberos is a network authentication system which allows clients and
servers to authenticate to each other using symmetric encryption and a
trusted third-party, the Key Distribution Center (KDC).
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)
All krb5 users should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the updated
packages, the krb5kdc and kadmind daemons will be restarted
