Amazon Linux 2023 : python3-pip, python3-pip-wheel (ALAS2023-2026-1689)

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1689 advisory.

pip prior to version 26.1 would run self-update check functionality after installing wheel files which required importing well-known Python modules names. These module imports were intentionally deferred to increase startup time of the pip CLI. The patch changes self-update functionality to run before wheels are installed to prevent newly-installed modules from being imported shortly after the installation of a wheel package. Users should still review package contents prior to installation. (CVE-2026-6357)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update python-pip --releasever 2023.11.20260514' or or 'dnf update --advisory ALAS2023-2026-1689 --releasever 2023.11.20260514' to update your system.
