Echo: python3.13: security update to 3.13.5-2+e34

medium Tenable Cloud Security Plugin ID 464964

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
 (CVE-2026-17084)

Solution

Update the python3.13 library and its related packages to version 3.13.5-2+e34 or later.
