OpenShift Enterprise by Red Hat is the company's cloud computing Platform- as-a-Service solution designed for on-premise or private cloud deployments. Jenkins is a continuous integration server that monitors executions of repeated jobs, such as building a software project or jobs run by cron. Security Fix: The Jenkins continuous integration server has been updated to upstream version 1.651.2 LTS that addresses a large number of security issues, including open redirects, a potential denial of service, unsafe handling of user provided environment variables and several instances of sensitive information disclosure.
