Descriptions

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.

La función do_standalone en MIT krb5 KDC del demonio de propagación de la base de datos (kpropd) en Kerberos v1.7, v1.8 y v1.9, cuando se ejecuta en modo autónomo, no maneja adecuadamente cuando un proceso hijo en funcionamiento "finaliza anormalmente", lo que permite a atacantes remotos provocar una denegación de servicio (finalización de la escucha de procesos, sin nuevas conexiones y una falta de actualizaciones en el KVC esclavo) a través de vectores no especificados.
