EulerOS 2.0 SP11 : python3 (EulerOS-SA-2025-2210)

critical Nessus Plugin ID 270015

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the python3 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 Allows arbitrary filesystem writes outside the extraction directory during extraction with filter='data'.


 You are affected by this vulnerability if using the tarfilemodule to extract untrusted tar archives using TarFile.extractall()or TarFile.extract()using the filter=parameter with a value of 'data'or 'tar'. See the tarfile extraction filters documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter for more information.

 Note that for Python 3.14 or later the default value of filter=changed from 'no filtering' to `'data', so if you are relying on this new default behavior then your usage is also affected.

 Note that none of these vulnerabilities significantly affect the installation of source distributions which are tar archives as source distributions already allow arbitrary code execution during the build process. However when evaluating source distributions it's important to avoid installing source distributions with suspicious links.(CVE-2025-4517)

 When using a TarFile.errorlevel = 0and extracting with a filter the documented behavior is that any filtered members would be skipped and not extracted. However the actual behavior of TarFile.errorlevel = 0in affected versions is that the member would still be extracted and not skipped.(CVE-2025-4435)

 Allows the extraction filter to be ignored, allowing symlink targets to point outside the destination directory, and the modification of some file metadata.

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

Solution

Update the affected python3 packages.
