## Description

schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 (aka krb5)
before 1.11.3 does not properly validate UDP packets before sending
responses, which allows remote attackers to cause a denial of service
(CPU and bandwidth consumption) via a forged packet that triggers a
communication loop, as demonstrated by krb\_pingpong.nasl, a related
issue to CVE-1999-0103.
