How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift-ansible package and not the openshift-ansible package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Python-RSA before 4.1 ignores leading '\0' bytes during decryption of ciphertext. This could conceivably have a security-relevant impact, e.g., by helping an attacker to infer that an application uses Python-RSA, or if the length of accepted ciphertext affects application behavior (such as by causing excessive memory allocation).
