An out of bounds write can occur when patching an Openshift object using the 'oc patch' functionality in OpenShift Container Platform 3.x. An attacker can use this flaw to cause a denial of service attack on the Openshift master API service which provides cluster management.
Find out more about CVE-2018-14632 from the MITRE CVE dictionary dictionary and NIST NVD.
A multi-master Openshift Container Platform cluster is more resilient, however a sustained attack would still have an important impact.
