CVE-2002-2443

CVE-2002-2443 affects MIT Kerberos 5 (krb5) kadmind, specifically the kpasswd service, where schpw.c does not validate incoming UDP packets. This can allow a remote attacker to cause a denial of service via a forged UDP packet that triggers a packet/communication loop, consuming CPU and bandwidth...
