Denial of Service Vulnerability in MIT krb5 KDC Database Propagation Daemon

CVE-2010-4022 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
