How to fix?

Upgrade SLES:15.0 python2-urllib3 to version 1.22-6.4.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python2-urllib3 package and not the python2-urllib3 package as distributed by SLES. See How to fix? for SLES:15.0 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.
