Amazon Linux 2 : python3 (ALAS-2025-2817)

medium Nessus Plugin ID 233979

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of python3 installed on the remote host is prior to 3.7.16-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2817 advisory.

A vulnerability has been found in the CPython `venv` module and CLI where path names provided when creating a virtual environment were not quoted properly, allowing the creator to inject commands into virtual environment activation scripts (ie source venv/bin/activate). This means that attacker- controlled virtual environments are able to run commands when the virtual environment is activated.
Virtual environments which are not created by an attacker or which aren't activated before being used (ie ./venv/bin/python) are not affected. (CVE-2024-9287)

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 'yum update python3' to update your system.
