FKIE_CVE-2010-4022

Vulnerability from fkie_nvd - Published: 2011-02-10 18:00 - Updated: 2026-06-16 23:24
Severity
Summary
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.
