CVE-2010-4022
The do_standalone function in the MIT krb5 KDC database propagation
daemon (kpropd) in Kerberos 1.7, 1.8, and 1.9, when running in
standalone mode, does not properly handle when a worker child process
'exits abnormally,' which allows remote attackers to cause a denial of
service (listening process termination, no new connections, and lack
of updates in slave KVC) via unspecified vectors.";

software upgrades.
