Summary
Moderate: python3.12 security update
Details
Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems.
Security Fix(es):
- cpython: wsgiref.headers.Headers allows header newline injection in Python (CVE-2026-0865)
- cpython: IMAP command injection in user-controlled commands (CVE-2025-15366)
- cpython: POP3 command injection in user-controlled commands (CVE-2025-15367)
- cpython: email header injection due to unquoted newlines (CVE-2026-1299)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Title
email BytesGenerator header injection due to unquoted newlines
Summary
The
email module, specifically the "BytesGenerator" class, didn’t properly quote newlines for email headers when
serializing an email message allowing for header injection when an email
is serialized. This is only applicable if using "LiteralHeader" writing headers that don't respect email folding rules, the new behavior will reject the incorrectly folded headers in "BytesGenerator".
