The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates, which results in SSL connections succeeding in situations where a verification failure is the correct outcome. This is related to use of the ssl_context, ca_certs, or ca_certs_dir argument.

Mitigation

The urllib3 package is used by elastic-curator, which is deployed in the ose-logging-curator, and used by the optional logging feature in OpenShift Container Platform (OCP). Therefore OCP 3.11 users can mitigate this issue by not deploying and using the Curator logging feature.

In OCP 4 urllib3 is also used by several Ansible Play Book images built with the Operator SDK and available for installation in OCP 4 including openshift-enterprise-ansible-operator and ose-metering-ansible-operator. Therefore those operators should not be deployed in order to mitigate this issue in OCP 4.
