Summary
python3 security update
Details

Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C++ (or other languages, depending on the chosen implementation). Python is also usable as an extension language for applications written in other languages that need easy-to-use scripting or automation interfaces.

Security Fix(es):

In CPython's email module, when folding a long comment containing exclusively unfoldable characters, the parentheses are not preserved. This could be exploited to inject headers into email messages in scenarios where email addresses are user-controlled and not sanitized.(CVE-2025-11468)

User-controlled data URLs parsed by urllib.request.DataHandler allow injecting headers through newlines in the data URL mediatype.(CVE-2025-15282)
