Descriptions

The StartServiceCtrlDispatcher function in the cvpnd service (cvpnd.exe) in Cisco VPN client for Windows before 5.0.06.0100 does not properly handle an ERROR_FAILED_SERVICE_CONTROLLER_CONNECT error, which allows local users to cause a denial of service (service crash and VPN connection loss) via a manual start of cvpnd.exe while the cvpnd service is running.

La función StartServiceCtrlDispatcher en el servicio cvpnd (cvpnd.exe) del cliente Cisco VPN para Windows versiones anteriores a 5.0.06.0100 no maneja correctamente un error ERROR_FAILED_SERVICE_CONTROLLER_CONNECT, permitiendo que usuarios locales provoquen una denegación de servicio (parada del servicio y perdida de conexión VPN) mediante un inicio manual de cvpnd.exe mientras se está ejecutando el servicio cvpnd.
