NVD Description

Note: Versions mentioned in the description apply only to the upstream python27:2.7/python2-pip-wheel package and not the python27:2.7/python2-pip-wheel package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

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.
