Amazon Linux 2023 : python3, python3-devel, python3-idle (ALAS2023-2025-900)

medium Nessus Plugin ID 233383

Language:

Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-900 advisory.

 The urllib.parse.urlsplit() and urlparse() functions improperly validated bracketed hosts (`[]`), allowing hosts that weren't IPv6 or IPvFuture. This behavior was not conformant to RFC 3986 and potentially enabled SSRF if a URL is processed by more than one URL parser. (CVE-2024-11168)

 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 python3.9 --releasever 2023.6.20250317' to update your system.
