Amazon Linux 2023 : python3.12, python3.12-devel, python3.12-idle (ALAS2023-2025-808)

high Nessus Plugin ID 214617

Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-808 advisory.

Starting in Python 3.12.0, the asyncio._SelectorSocketTransport.writelines()method would not pause writing and signal to the Protocol to drainthe buffer to the wire once the write buffer reached the high- watermark. Because of this, Protocols would not periodically drain the writebuffer potentially leading to memory exhaustion.





Thisvulnerability likely impacts a small number of users, you must be usingPython 3.12.0 or later, on macOS or Linux, using the asyncio modulewith protocols, and using .writelines() method which had newzero- copy-on-write behavior in Python 3.12.0 and later. If not all ofthese factors are true then your usage of Python is unaffected. (CVE-2024-12254)

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 these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update python3.12 --releasever 2023.6.20250123' to update your system.
