Amazon Linux 2023 : python3.11, python3.11-devel, python3.11-idle (ALAS2023-2025-871)
medium Nessus Plugin ID 233393
Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-871 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)
The Python standard library functions `urllib.parse.urlsplit` and `urlparse` accepted domain names that included square brackets which isn't valid according to RFC 3986. Square brackets are only meant to be used as delimiters for specifying IPv6 and IPvFuture hosts in URLs. This could result in differential parsing across the Python URL parser and other specification-compliant URL parsers. (CVE-2025-0938)
During an address list folding when a separating comma ends up on a folded line and that line is to be unicode-encoded then the separator itself is also unicode-encoded. Expected behavior is that the separating comma remains a plan comma. This can result in the address header being misinterpreted by some mail servers. (CVE-2025-1795)
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 python3.11 --releasever 2023.6.20250303' to update your system.See Also
