Red Hat OpenShift Container Platform is Red Hat"s cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the RPM packages for Red Hat OpenShift Container Platform 3.9.51. See the following advisory for the container images for this release: https://access.redhat.com/errata/RHBA-2018:2907 Security Fix: * atomic-openshift: oc patch with json causes masterapi service crash For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section. Red Hat would like to thank Lars Haugan for reporting this issue. Bug Fixes: * Events on `storage` in Internet Explorer 11 were triggered in the same window tab, whereas in other browsers, the events were triggered in duplicate tabs. This issue caused the request to time out when logging into the console in Internet Explorer 11. This bug fix enables `inactivityLogoutKey`, and ensures that all tabs are logged out before timing out. As a result, Internet Explorer 11 logs out on the same conditions as other browsers. * Previously, fluentd generated events internally with the `OneEventStream` class. This class does not have the `empty?` method. The Kubernetes metadata filter used the `empty?` method on the `EventStream` object to avoid processing an empty stream. Fluentd issued error messages about the missing `empty?` method, which overwhelmed container logging and caused disk issues. This bug fix changed the Kubernetes metadata filter only to call the `empty?` method on objects that have this method. As a result, fluentd logs do not contain this message. * RubyGems FFI 1.9.25 reverted a patch which allowed it to work on systems with `SELinux deny_execmem=1`. This reversion caused fluentd to crash. This bug reverts the patch reversion. As a result, fluentd does not crash when using `SELinux deny_execmem=1`. * The fix for BZ1628371 introduced a poorly built shared library with a missing symbol. This missing symbol caused fluentd to crash with an undefined symbol: rbffi_Closure_Alloc error message. This bug fix rebuilds the shared library with the correct symbols. As a result, fluentd does not crash. * Previously, the `json` was the default log format for an audit. This format caused the audit log to print using JSON format. This bug fix allows you to set the format as specified in *_master-config.yaml_*. As a result, the audit log contains values per configured log format. * Previously, when using Docker with the journald log driver, all container logs, including system and plain Docker container logs, were logged to the journal, and read by fluentd. Fluentd did not know how to handle these non-Kubernetes container logs and threw exceptions. This bug fix treats non-Kubernetes container logs as logs from other system services, for example, sending them to the .operations.* index. As a result, logs from non-Kubernetes containers are indexed correctly and do not cause any errors. All OpenShift Container Platform 3.9 users are advised to upgrade to these updated packages and images.
