NVD Description

Note: Versions mentioned in the description apply only to the upstream python312-tools package and not the python312-tools package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

The "stringprep" module didn't process characters from RFC 3454 tables B.2 or B.3 correctly: the latest Unicode codepoint attributes were used instead of the specified Unicode 3.2.0. This behavior would cause mismatches when processing domain names using IDNA 2003 (the "idna" codec) and the in_table_b2() function of the "stringprep" module. This only affects domain names containing characters that were not previously registered or had their Unicode attributes such as case-folding behavior updated since Unicode 3.2.0.
