NVD Description

Note: Versions mentioned in the description apply only to the upstream python313-base package and not the python313-base package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

When calling base64.b64decode() or related functions the decoding process would stop after encountering the first padded quad regardless of whether there was more information to be processed. This can lead to data being accepted which may be processed differently by other implementations. Use "validate=True" to enable stricter processing of base64 data.
