An out of bound write can occur when patching an Openshift object using the 'oc patch' functionality in OpenShift Container Platform before 3.7. An attacker can use this flaw to cause a denial of service attack on the Openshift master api service which provides cluster management.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2908 advisory.

    Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution     designed for on-premise or private cloud deployments.

    Security fix(es):

    * A privilege escalation vulnerability exists in OpenShift Container Platform 3.x which allows for     compromise of pods running on a compute node to which a pod is scheduled with normal user privilege. This     access could include access to all secrets, pods, environment variables, running pod/container processes,     and persistent volumes, including in privileged containers. Additionally, on versions 3.6 and higher of     OpenShift Container Platform, this vulnerability allows cluster-admin level access to any API hosted by an     aggregated API server. This includes the servicecatalog API which is installed by default in 3.7 and     later. Cluster-admin level access to the service catalog allows creation of brokered services by an     unauthenticated user with escalated privileges in any namespace and on any node. This could lead to an     attacker being allowed to deploy malicious code, or alter existing services. (CVE-2018-1002105)

    * atomic-openshift: oc patch with json causes masterapi service crash (CVE-2018-14632)

    Bug Fix(es):

    * During etcd scaleup, facts about the etcd cluster are required to add new hosts. This bug fix adds the     necessary tasks to ensure those facts get set before configuring new hosts, and therefore, allow the     scaleup to complete as expected. (BZ#1578482)

    * Previously, sync pod was not available when the Prometheus install checked for available nodes. As a     consequence, if a custom label was used for the Prometheus install to select an appropriate node, the sync     pods must have already applied the label to the nodes. Otherwise, the Prometheus installer would not find     any nodes with a matching label. This bug fix adds a check to the install process to wait for sync pods to     become available before continuing. As a result, the node labeling process will complete, and the nodes     will have the correct labels for the Prometheus pod to be scheduled. (BZ#1609019)

    * This bug fix corrects an issue where a pod is stuck terminating due to I/O errors on a FlexVolume     mounted on the XFS file system. (BZ#1626054)

    * 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. (BZ#1626552)

    * 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`. (BZ#1628405)

    * This bug fix updates the *_redeploy-openshift-ca.yml_* playbook to reference the correct node client     certificate file, `node/client-ca.crt`. (BZ#1628546)

    * 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. (BZ#1628798)

    * 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. (BZ#1632361)
