ALSA-2023:6494 — Moderate: python3.11 security update

2026-10-08T18:54:57.035418+00:00

Affected: AlmaLinux:9: python3.11, AlmaLinux:9: python3.11-debug, AlmaLinux:9: python3.11-devel, AlmaLinux:9: python3.11-idle, AlmaLinux:9: python3.11-libs, AlmaLinux:9: python3.11-test, AlmaLinux:9: python3.11-tkinter

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.

The following packages have been upgraded to a later upstream version: python3.11 (3.11.5). (BZ#2210785)

Security Fix(es):

* python: tarfile module directory traversal (CVE-2007-4559) * python: file path truncation at \0 characters (CVE-2023-41105)

CVE-2023-41105

2026-10-08T18:54:57.035493+00:00

Affected: python

An issue was discovered in Python 3.11 through 3.11.4. If a path containing '\0' bytes is passed to os.path.normpath(), the path will be truncated unexpectedly at the first '\0' byte. There are plausible cases in which an application would have rejected a filename for security reasons in Python 3.10.x or earlier, but that filename is no longer rejected in Python 3.11.x.
