Red Hat Security Advisory 2014-1796-01 – OpenShift Enterprise by Red Hat is the company’s cloud computing Platform-as-a-Service solution designed for on-premise or private cloud deployments. It was reported that OpenShift Enterprise 2.2 did not properly restrict access to services running on different gears. This could allow an attacker to access unprotected network resources running in another user’s gear. OpenShift Enterprise 2.2 introduces the oo-gear-firewall command which creates firewall rules and SELinux policy to contain services running on gears to their own internal gear IPs. The command is invoked by default during new installations of OpenShift Enterprise 2.2 to prevent this security issue.
