Last modified Jun 16, 2026

CVE-2010-4022 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.65% chance of exploitation in the next 30 days.
