Bugzilla: 664009: CVE-2010-4022 krb5: kpropd unexpected termination on invalid input (MITKRB5-SA-2011-001)

Details

The MITRE CVE dictionary describes this issue as:

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.
